Serge Modular Music Systems Modules

“Here we have 2 vintage serge modular music systems smms modules attached to a clear custom unlabelled front panel and power supply. The previous owner says they were probably from around 1980 or so and didnt remember anything else about them – 40+ years is a long time!

The modules appear to be the wonderful wave multiplier and triple comparator, but we’re not sure so see pics and do your own research before buying so you know what to expect. If it IS the wave multiplier, this is one of the most sought after of serge modules as it sounds like nothing else.

These came out of a cabinet with Aries modules (being sold separately) and are untested. Assume they’ll need repair.

Sold as is with no guarantees of any sort, but make sure you have the skills or resources needed to get them up and running if need be. ” Click here to visit listing on eBay

Frank Eventoff Sonica

“Ever feel like you are literally DROWNING in musical instruments? No? Then you are not me. I need to get rid of the under-played instruments from my basement. Some of them are great, as I’ll be the first to tell you. Some are not great, and I’ll tell you that too. All of them looked interesting to me at some point. Maybe they’ll be interesting for you too.

This is a rare (650 made), limited edition (see previous) SONICA electronic instrument. Designed and built by Franklin Eventoff as a test bed for his Force Sensing Resistor technology. The test having been passed, he licensed it to Mattel and others, and Eventoff continues to develop and manufacture FSR’s to this day. The seed from which all this grew, the Sonica consists of a neck with the FSR’s, marked off in 2 octaves of whole-note scales, attaches to a body that contains a Serge Tcherepnin Voltage-Controlled Oscillator, a wide range tuning knob, a volume knob, and 3 other FSR’s for pitch bend, tone, and half-step up. An internal amp and speaker let you play as long as the 9v battery holds out. This one works, though sometimes the lower octave FSR is a little wonky. Comes with instruction sheet and foam-lined case. Low start price of FOUR HUNDRED FIFTY-NINE DAMN U.S. DOLLARS, because of the occasional wonky lower octave. Plus, shipping is FREE in THE CONUS.” Click here to visit listing on eBay

Frank Eventoff Sonica

“You are viewing an extremely rare Sonica synthesizer built by Frank Eventoff in 1979. Only 650 of these were ever made. Very few are now known to exist. The body is carved of mahogany with brass plates and has a plaque on the back of the head, engraved with the production number (#199). It comes with the original custom-sized case and an original warranty card (stamped and unused).

Original Speaker cloth has some dry rotting due to age, but the speaker works great and is all original. Picture shows some light blemishes to body, but overall, unit is in excellent condition. Clean battery compartment and terminals.

Top of unit features three buttons. Analog “Slider” which is a tremolo type effect, Analog “Tone” which is actually a tonal boost, and “Half-Step” which raises the note an octave. It features a built-in speaker, with an 1/8 inch output to connect to an amplifier or recording device. It runs on one 9-volt battery which is installed by accessing a plate on the backside of the device.”

Serge Modular

“STS/Oakland era custom panel with extremely useful oscillator sync mod on both PCO’s. The sync is much stronger than stock, making it very easy to lock in harmonic or subharmonic relationships, basically anything musically useful. This is an absolute requirement for live patching.

As you can see this panel is absolutely packed with functionality! Much more so than shop panels. It still works and sounds great after 20+ years.
