Oberheim OB-MX 12 Voice Cross Section

via this auction.
"Rich, warm, swirlling textures are created with 32 knobs, 47 buttons, and many many MIDI controllable cross modulations(pan, pulse width, osc sync, even "analog" FM. Bright, M1 size green display, with a simple user interface. 3 LFO's(triangle, forward and reverse sawtooth, and random, with a sample and hold feature for generating "computeresque" LFO sounds or a square LFO) Up to 6 oscillators (Triangle, Sawtooth, Pulse Width) per voice. Oberheim Filter(with adjustable resonance, hipass, lowpass, and bandpass), plus a "Mini-Moog" style 24 Db resonant low-pass filter. Signal to Noise ratio is EXCELLENT(better than some "super-clean" digital synths), around 88-92 db for most patches."

Guess the other synth.

The Sonica with Serge Oscillator

Remember The Sonica? Looks like one is up for auction. Title link takes you to the shots.

Note this one and the Black Coffee below is a bit of a fund raiser.

"Up for auction here is the very rare Frank Eventoff Sonica. It's a one oscillator analog synth built into a wood guitar shaped controller. The oscillator was built by Serge electronics. Yes the same who build high end modular synths! It has its own speaker and runs on a regular 9v battery. It's about 18" long. It's number 276 out of 650. With this instrument you are officially the King or Queen of the hippie synth nerds (certificate not included).

Here's a link to the entertaining history of the Sonica.

This unit for auction is in very good shape cosmetically and works 100%. However because of the age of the electronics, it's being sold as-is. I already fixed a bad solder joint on the fretboard. You will probably have to do the same some time in the future. The fretboard flexes slightly even with a light touch. Solder joints don't like flexing. If the Sonica sounds continuously without you touching it, heat up the solder joints on the fret board and it will fix it. It's just the way the Sonica is designed. At least I told you about it and how to fix it, you'll notice no other sellers of Sonicas mentioned it. Also, some of what look like scratches in the pics are just reflections from the light.

You get the Sonica, its custom case, instruction manual and blank warranty card.

Sorry about the watermarking on the photos below, it's a necessity now because of scammers that ebay seems to tolerate.

So you can rationalize your gear lust: you're helping me pay to get rid of a brain tumor. You're not a gearhead, you're a humanitarian!"

Note I usually shy away from posting images with watermarks. If you have an auction with great shots and watermarks and you are wondering why I haven't posted it, that's probably why. Just shoot me an email and I'll post it. BTW, I'll post anything on Matrixsynth-b regardless of the shots, so feel free to send them in.
