It’s hard to keep this site updated especially since the last few months have been a whirlwind of activity, for which I am incredibly grateful. The summer brought shows in Texas, Iowa, Kansas, Missouri, Nebraska, Chicago, Quebec, and Ontario with Laura Rain & The Caesars as well as the Ottawa Blues Festival with Thornetta Davis. organissimo played several festivals in Michigan including the unCaged Festival in Northport and the Shoreline Jazz Festival in Muskegon. We also released and new CD in September called Live At The SpeakEZ (that’s two new organissimo CDs in 2017). This fall I was in Belgium for a few short days for two shows with Big Apple Blues and we’re finishing up a new record with that group as well. And I did a handful of other recording, mixing and mastering sessions as well.
On the gear front, I am proud to announce an endorsement with Kurzweil Music Systems and Weisersound. I am using a Kurzweil Forte 7 on stage and in the studio and I absolutely love it. It is an extremely beautiful keyboard, built like a tank, with an easy to use interface, great sounds, lots of room for your own sounds and samples, and more. Here are a couple of demo videos I made, the second one featuring THEO drummer Kevin DePree.
Contact David Weiser at Weisersound for your Forte and get VIP support, free custom patches, and the best customer service on the planet. He’s a personal friend and a great person.
Also, I am now the proud owner of the new flagship from Hammond Organ USA, the Hammond XK5. I will be with Hammond in their booth at the 2018 Winter NAMM show in January demonstrating the XK5 and all it can do. I plan on making a custom tonewheel set for it, as I’ve done with previous Hammond models. And expect some video demos as well in the near future. Here’s a brief live-stream I did on Facebook on the day I received the XK5 last week. The sound quality of FB live-streams isn’t so great, but you can get a feel of how it sounds. That’s the internal digital Leslie simulator, by the way.
This winter I will be heading to NYC for some recording sessions but mostly staying in Michigan, working on the upcoming sophomore THEO album, another Jim Alfredson’s Dirty Fingers album, and the album that Lawrence Barris and I did with the legendary drummer Harvey Mason (Herbie Hancock, Bob James, George Benson, etc). Speaking of Mr. Mason, we are performing with him on December 11th at the Wealthy Theatre in Grand Rapids, MI.
My event calendar is updated through December so you can see where I’ll be if you want to make a show. Happy Holidays and be safe this season!
I’m really excited to announce the launch of my PledgeMusic campaign for THEO. THEO is my progressive rock project, a musical endeavor I’ve been working on for the last four years. It’s quite different from the type of music I’m known for (ie jazz and blues) but in many ways is a return to my roots.
I’ve teamed with PledgeMusic to bring THEO to fruition. And there’s a bunch of cool stuff you can pre-order including a hi-res digital download of the album, CDs, 5.1 surround mixes, t-shirts, keychains, Leslie pedals, and even a Privia PX5s!
Check it out and snag your copy today. And when you do, share the page with your friends.
Big John Patton was a big inspiration on my playing and I’m very proud of this record. It is the only tribute album for him of which I’m aware. Enjoy and please subscribe to my YouTube channel.
I really enjoy old corporate technological films and thankfully so do a lot of other people on YouTube. I’m not ashamed to admit I spent a day watching old Fairchild Seminconductor films recently. And I enjoyed every minute of them.
I found this video a few years ago and it’s incredible. A tour of the Hammond factory probably circa the late 1950’s. It describes the concept of tonewheels and their manufacture, as well as the voicing of each instrument.
The most surprising piece of information to me was the statement about “five Hammond organ plants”. I had no idea the company was that large at one time.
I also love the part about the trained technician checking each tonewheel by ear to make sure it sounds correct. This is why the tonewheel organ is, in many ways, like an acoustic instrument. The organ is ‘voiced’ by a technician, just like an acoustic piano. Technicians would hand-pick each filter capacitor in the generator in order to mold the overall tone to their liking. They even signed the tone generator with their initials.
My late father referred to the Hammond organ as a prime example of what he called “post-WWII over-engineering”. They really are amazing products from the golden age of American manufacturing and engineering.
My custom tonewheel sets for the SK series and XK1c are available for free download over on the Hammond Organ USA site.
Look at the left-most column about one-third of the way down for Jim Alfredson’s Custom Tonewheel Settings.
Hammond USA site
The custom tonewheel sets are based on my beautiful 1954 Hammond C2 that graces my humble home studio. You can hear that organ on organissimo’s Dedicated CD. It’s one of my favorite Hammonds with a full, rich, thick tone especially in the upper end. You can read more about how I created the set and watch comparison videos between the SK2 and the Hammond C2 in this post.
KIOS FM in Omaha NE has named my CD, Jim Alfredson’s Dirty Fingers – A Tribute To Big John Patton as a Top 12 release in 2013. I’m thankful and honored.
As a companion to my Hammond XK1c Quick review, here’s a video demo of the XK1c in action. I took one of the tracks from my Tribute To Big John Patton sessions last August and muted the original organ track. I then overdubbed myself playing the XK1c instead. I think it sounds very good! Such demos are important because they demonstrate how the instrument fits into a mix with a band.
I considered connecting the XPK-200L bass pedals to the XK1c and kickin’ a bit of bass, but I decided to just do left hand bass instead.
The XK1c was recorded directly into Cubase 7 from it’s 1/4″ outputs. The onboard Leslie sim is used. I added a bit of the session reverb from the track to help it sit into the “room” with the other instruments.
Hammond is shipping their newest model, the XK1c. This replaces the discontinued XK1. The engine is much the same as the SK series but without the other non-organ voices. The form factor is also very similar but lacking the SK’s non-organ voice controls. It also features different end blocks with a more traditional wood grain.
Hammond XK1c
The organ engine has a few differences from the current OS in the SK series (though this may change). First is a MIX parameter for the chorus/vibrato, which controls the balance between the dry signal and the affected signal. Users have been asking for this ability for some time. It allows you to dial in some “age” to the virtual chorus/vibrato line, not unlike the capacitors in a real tonewheel organ aging over time. The range is from -64 (dry) to +64 (100% wet).
Another difference is the COLOR parameter in the Leslie simulation menu. This imparts some tonal characteristics reminiscent of cabinet resonance to the Leslie sim.
Hammond also added some very subtle details to make the sound even more authentic. The drawbars exhibit a very understated ‘click’ in the audio when moved. It is barely noticeable but tonewheel Hammond organs do the same thing, even those with smooth drawbars. A similar understated ‘click’ is audible when holding a note or chord and pressing the chorus/vibrato tabs on or off. Again, a tonewheel console like a B3 does this as well and it isn’t loud or distracting.
Here is a quick improvisation using the very first stock preset on the XK1c and the internal Leslie sim. This was recorded straight into Cubase 7 with no external processing except for a very light limiter added to the final mix for web delivery purposes. The reverb is also from the XK1c.
The sound right out of the box is very good. To my ear, Hammond’s past instruments all needed substantial tweaking before they sounded as good as their potential, but the XK1c comes from the factory sounding really great. The presets are for the most part well programmed and display the range of tones available. One of my favorites is a re-creation of a 1940’s Hammond BV through a Leslie 31H tallboy.
I will be making a custom tonewheel set for it based on my ’54 Hammond C2 and this will be available on my site as well as the Hammond site for free.
I think Hammond has a real winner with this product. A 13lbs Hammond organ with the big sound of the original 400lbs beast for $1495? Sounds good to me!
Back in April I posted a video on Youtube comparing my newly completed tonewheel set for the Hammond SK2 with its inspiration, my beautiful 1954 Hammond C2. I bought the C2 from a pawn shop in Grand Rapids in 1998. They were using the back panel, which is detachable, as a board to post notices with push-pins. The rest of the case was in pretty rough shape. I feel like I rescued it from certain death. And the best part is that it was only $400.
The other best part is that it had smooth drawbars instead of the usual ratchet style drawbars that were standard on the 2 series. I’m fairly confident that the smooth drawbars were installed at the Hammond factory due to the serial number, which dates the organ to the end of 1954. I think this C2 was one of the last off the line before they started making the C3 model, all of which had smooth drawbars. I installed a TrekII percussion unit to bring it up to B3/C3 specs and also a 122 Leslie output. My dad and I refinished the organ, too. Well, pretty much my dad did the work. He’s gone now and so the organ has a lot of sentimental value for me.
1954 HammondC2 – Ain’t she purdy?
It’s also one of my favorite organs in terms of sheer tone, sentimentality aside. Everything is stock with the exception of the chorus/vibrato line. I replaced the capacitors in the line and also replaced the resistor underneath the C/V tabs so the chorus is a bit deeper and more like the 3 series. Everything else is from the factory. You can hear it on the organissimo release Dedicated. You can hear and see it in action on this video from my Kickstarter promotion as well as this video.
When Hammond added the ability to adjust the virtual tonewheels in the SK series of digital organs, I knew instantly the first organ I wanted to try and match. So I spent an afternoon comparing the two organs one tonewheel and one drawbar at a time until I got the SK to sound as close as I could. I posted a video on Youtube of the results with the caveat that you cannot see which organ I’m playing. Astute viewers will notice the orientation of each organ that’s off camera with my previous videos of the C2 and would be able to deduce pretty quickly which is which. I also overlooked a very important setting in the SK2 that controls the percussion. I accidentally had it set to re-trigger on every note. The percussion in a real C3 or B3 is polyphonic but single-trigger, meaning if you’re holding any key down, it won’t re-trigger unless you lift your fingers off the keys. That combined with a bit too much brightness in the keyclick makes figuring out which is which a bit less difficult, although certainly some people were fooled. Here’s the original video:
I’ve been tweaking my custom tonewheel set for the SK series ever since, taking into account how it sounds through various speaker systems, Leslies, stages, gigs, etc. I’ve also been experimenting with running the SK into the C2’s preamp. The following clip is an example of that.
The signal flow is as follows: SK2 into the C2 preamp via the RCA jack on the expression pedal box, C2 preamp direct out via a custom direct box into a mixer, the mixer aux output into a Mini Vent, the Mini Vent stereo output to my DAW.
I posted this clip on the Keyboard Forum and the responses were interesting. Some could not tell the difference. One poster asked if I had put the SK through the C2 preamp. Some correctly identified the SK. One fellow poster claimed that routing the SK into the C2’s preamp was unfair, since you’re not going to have that luxury in a live situation (although I’ve been toying with the idea of finding an AO-10 preamp and wiring it up with 1/4″ jacks to go in between the SK and my Leslie!) Point taken. The AO-10 preamp from the C2 definitely puts a cool vibe on the SK’s signal. So what’s the actual difference? I decided to inject some white noise into the preamp and see what’s up in a spectral analyzer (with the awesome and free Voxengo SPAN).
Here is the raw unaffected white noise signal:
White noise from the Test Tone generator in Cubase 7.
And here is the white noise after it goes through the AO-10 preamp in the 1954 Hammond C2.
White noise after going through the AO-10 preamp.
Look at that beautiful gentle roll-off in the high-end. The whole signal takes on a nice rounded curve rather than the straight linear line of the original signal. This of course is not very scientific and only reveals a fraction of what’s going on in the preamp. There is harmonic distortion, slewing, filtering, and all many of things going on in there. But it did give me a starting point to try and shape the output of the SK to sound more like the C2’s output without resorting to “cheating” and running the SK through the C2.
I started by using the onboard EQ parameters in the SK2. It has per-patch EQ and also global EQ via the knobs on the front panel. The per-patch EQ is quite powerful and includes the “TC” parameter which emulates the tone control adjustment on the original Hammond preamps like the AO-10. I have the tone control turned all the way up on my C2, so I set this parameter to -1 in the SK. According to the manual, -1 represents the knob all the way up. The SK actually allows you to adjust it beyond the real-life maximum, which yields some interesting results. Once that was set, I used the per-patch EQ to shape the signal a bit more, trying to match the timbre of the C2. I found that adjusting the low mids made a very big difference.
So here is the result. The following video features the raw, unprocessed output of the C2 against the raw, unprocessed output of the SK2. The SK2 is NOT routed through the C2’s preamp. Both organs’ outputs are going straight into the DAW. No Leslie, no Leslie sim, no outboard EQ, nothing. Just straight out of the two organs and into the computer.
Watch the video and see if you can detect which organ is which. Listen for the quality of the key-click, the tones behind the main frequency of the notes, and the timbre of the percussion. Later in the video I turn the chorus on both. Listen to the depth of the chorus and the shimmer. Write down which organ you think A is and which you think B is and then watch the video below so see if you’re right.
Don’t cheat! Watch the first video before watching the one below.
How’d you do? The differences are minor but they are there. They are almost to the point where they are not much different than two different console Hammonds. My ’74 B3 certainly sounds different ’54 C2. The key areas of the SK that can be improved are:
Distortion – There’s some fuzz around the edges of the real thing, due to the preamp. That difference gets much smaller when the SK2 is run through the preamp. I can kind of mimic it using a small amount of the onboard overdrive, specifically the SK’s EP model which is much more subtle and better sounding than the TUBE model.
Leakage – In order to try and mitigate the leakage, Hammond moved the location of certain tonewheels in the generator throughout the years. Since the VASE III engine was originally modeled on a 70s B3, the last of the line, it represents Hammond’s final arrangement of tonewheels. And that arrangement is different than my ’54 C2* (see addendum 1 below). So the character of the individual tonewheel leakage on some notes is different between the two, because the ’54s tonewheels are in different positions. I got them as close as I can but I cannot change the actual frequencies involved in the leakage.
Chorus / Vibrato – The ’54 is very different than the mid-60’s A100 that the SK’s c/v is modeled after. They do not sound the same.That said, I don’t think one is necessarily better than the other, just different. Nor do I have a mid-60s organ to compare it to but the SK2 chorus sounds very good to me. I’m excited about having the new Mix Balance control that was introduced in the XK1c on the SK. That might help to get it closer to the ’54.
I’d like to see Hammond offer models of various eras of c/v, including the very cool and unique 2nd tone generator chorus of the BC model. Then again, I’m probably the only one that cares!
To summarize, we’re nitpicking over extreme minutia here. Are these issues important in the midst of a burning solo while competing with a distorted guitar, bashing drums, and thundering bass guitar? Probably not. Will they even be apparent in the average supper club jazz trio setting? Not really. Your choice of amplification has a greater effect on the sound than whether or not the keyclick is 100% authentic or the leakage is 100% historically accurate. We’ve gotten to the point where we can take a 35lbs two manual organ to the gig rather than a 400 pound back-breaker. What a great time to be a musician! We’re 95% there in terms of tone. That extra 5% isn’t necessarily a deal-breaker, but its still fun to try and get there.
Thanks for reading and please subscribe to my Youtube channel if you like the videos. And leave a comment below or contact me via Facebook if you’d like my SK tonewheel set for your SK.
* Addendum 1 – According to my friend and Hammond guru Todd Phipps (ie B3Nut), I am incorrect in stating that Hammond moved the tonewheels between 1954 and 1974. Todd wrote on my Facebook thread:
…the arrangement of the tonewheels in your ’54 is the same as a late B-3 – the change from a sequentially-wired terminal strip to a chromatically-wired terminal strip with the narrow brass generator cover took place around 1952. A red-cap generator from a ’74 B-3 will drop right in and wire right up. The reduced leakage of the later red-cap instruments is partly due to the more stable/accurate filtering of the later filters as well as the RC networks on several of the frequencies that got rid of low-frequency rumble on those tones.
That makes sense and aligns with what I hear on the C2, especially in the middle range. There is a LOT of low frequency information in those tones that is not there on the SK2 nor is it there on my ’74 B3.
* Addendum 2 – Over on the Keyboard Forum thread and my Facebook thread, I talked about the possibility of Hammond adding a scaling parameter to the SK’s keyclick LPF. I noticed that the keyclick gets duller as you go down into the bass ranges on the C2 but it stays the same on the SK. The SK has a LPF parameter in the keyclick submenu but it is static, ie it affects all notes equally. If it was tied to note values with a scaling parameter, it could more authentically emulate the C2.
However, I incorrectly assumed the cause of the dullness in the bass range of the C2 was due to filtering. Again, Todd Phipps corrected me:
… keyclick is mainly a product of the instant switching of the sine waves at something other than zero cross (and there’s a bit of contact bounce in that mix too.) The higher the frequency being switched, the stronger the HF component of the switching transient.
And again, this makes a lot of sense. Todd helped me modify the chorus/vibrato on my C2 to more closely match the 3 series organs and is a wealth of knowledge on the tonewheel organs. Thank you, Todd!
* Addendum 3– Hammond just released the XK1c which is like an SK series organ but without the extra voices. The XK1c has some features that the SK series does not yet have, although Scott May from Hammond mentioned on FB that the features are coming for the SK series via an OS update soon. One of the coolest features in the new XK1c is the MIX parameter in the chorus/vibrato submenu. This parameter lets you balance the dry, non-affected organ signal with the chorused signal and helps dial in a smoother, more vintage sounding chorus. Check out my quick review of the XK1c to hear it in action.
