"Roland TB-303 Bass Line Synthesizer for sale. This TB-303 sounds incredible. It has been well taken care of in a non-smoking, climate-controlled studio. It comes with the original Roland travel bag for the 303 and it is in pristine condition. Everything has been tested: DIN Sync, CV/Gate, all buttons work without issue and all potentiometers sound clean.
The serial number is 164,200 - Made in Japan. Comes with BOSS PSA-120S - Roland's recommended power supply. This is the real deal, analog TB-303 in excellent condition. Instantly ready for your studio, live set-up or for whatever you need it for."
"This is one phenomenal instrument. It lives and breathes a beautiful sound of its own. Out of everything I have to sell to go to Vet school this is the one piece I still want to hang on to.
I had this plugged into a Strymon Timeline and Bluesky and the results are literally awesome. There's some patch sheets on Muffwiggler that got me started and then I just got into it from there.
I got this brand new earlier in the year and it still smells like fresh cut wood - awesome!
It comes complete with a stereo output jack, power supply and 26 PVC stacking banana plugs (various lengths) from Test Path so you'll have everything you need to plug and play right away.
This is the ticket to unique one-of-a-kind sounds, atmospheres and drones in your music and film scores.
"This thing has undoubtedly seen it's share of action over the years. It has quite a few nicks, scratches and dents. Just by looking at it you can almost hear the countless attempts to play Frankenstein that have been tried on it. This is literally one that is going to be tough to see leave.
This Minimoog is definitely not a museum piece. It is not all original and has it's share of issues, but it is a great instrument. It is what we would call player's grade, and I would love it to go to a home where it will get the crap played out of it.
Let's get down to the details.
- First the serial number and completion signatures would indicate that it was created in 1974.
- Everything is in working order and sounds great, as I literally had put $500 into it getting it up and running less than 1 month ago. I had it serviced by Mike Borish over at Borish Electronics who is one of the best here in Chicago for old synths.
- Mike was able to replace any grommets on the keyboard so there are no clacking keys that plague these boards.
- Several pots have been changed out as well as a new power cord.
- There is a scratchy switch, but only one and it is the 440 signal for tuning. Only make a scratching noise when switched on or off.
- The keyboard is not perfectly level, as seen in the photos. It is very playable however.
- It is missing screws for one bracket on the actual wooden frame, you can see that in photo #21. The frame is rock solid however.
- Has a strange flaw in the finish on the top front panels that can only be seen in certain light, shown in photo #13
- Keep in mind that things have been changed out on this, so it can not be considered all original.
There are just a few pots that are still a little scratchy, but nothing major. I also have not had the chance to try the external controller connections so cannot say if those work or not. There does seem to be a little static from the high output jack, but the low output jack works just fine."

FM Synthesis is not just for DX7 and Yamaha synths. The Oberheim Matrix-12 can do primitive FM as well, albeit a single carrier and modulator pair. Here are some tips and tricks for exploring the FM possibilities. Some of the ideas come from my Getting Started Programming FM video, so you may want to check that out too."

K3021 Master VCO Module Demo Published on Sep 27, 2016 KilpatrickAudio
"Check out the K3021 Master VCO module from Kilpatrick Audio. This module offers the same amazing sound and features as half of the K3020 Dual VCO in a compact and affordable module."
"Eurorack Triangle Core VCO with Waveshapers - 18HP
Built on the success of the K3020 Dual VCO, the K3021 Master VCO offers a single channel oscillator based on this famous design. Completely redesigned to replace now hard to find parts, the K3021 uses a complete new triangle core design based around discrete transistors for an amazing tone excellent stability. Useful as both your main pitch oscillator and as a complex low-frequency signal source (LFO) the K3021 Master VCO is a workhorse module great for any system.
One of the features that makes the K3021 extra special is its use of complex waveshapers and pulse width modulation circuits to create unique timbres. You can select between sine, triangle and ramp waveforms for the WAVE section. These waves then feed into the triple pulse width modulator to create very rich pulse waves that have a much more lively character than a simple single-channel PWM. Choose from one of three PULSE output combinations for unique variations.
The BLEND and PULSE outputs can be used independently, or can be combined through the use of the ultra-low distortion blend section. Smoothly fade between the WAVE and PULSE waveforms either manually or with voltage control. By using the blend circuit especially with the LFO mode engaged, very complex modulation waveforms can be easily created.
