"This is an ARP 3620 keyboard for the ARP 2600 synthesizer. The 3620 improved on the older 3604P keyboard, adding two-voice polyphony, an LFO, portamento, envelope retrigger, octave transpose, and other features that greatly expanded the sound palette of the 2600. This particular unit is in very nice condition. It was serviced and recalibrated earlier this year by an experienced ARP tech, and it plays great with no problems whatsoever..."
Some good news on the eBay front. eBay now appears to keep ended auction listings all the way back through 2011! One question I commonly get is how much I think a given synth is worth. The answer is it depends on condition, supply and demand, and who's looking, but the easiest thing to do is to see what it went for on eBay. The problem until now was that eBay only kept ended listings up for 90 days. Well, it appears they have now made listings available all the way back through 2011. If you are curious what a given synth might fetch, search for it and the word auction on the top left here on MATRIXSYNTH and take a look at some listings. Remember to sort by date when the results come up if you want to view posts in order. You can also check out the condition items when for via the pics and descriptions.

"This is an extremely rare synthesizer and a serious collectors item. To my knowledge Eric only made 13 of these units and this is serial number 8. I've taken a pic of the Serial Number. I'm hoping this unit goes into a loving synth home where it will be appreciated and honored. This is a synth for the most elitist of synth collectors / geeks ( like me! ) 8-)
As far as I know, Eric personally assembled every PT2 by himself. And it shows, this thing is built like a tank. I've never seen a metal case this sturdy before...
And an FYI: You will need a CV converter for the PT-2. There is no MIDI. You will also probably need to calibrate the synth internally to get it to track to your CV converter.
The PT-2 is a very unusual synth, and is capable of creating some unique timbres that no solid state synth can create. I personally used it with my modular rig and came up with some pretty cool sounds..."

"You can use it as an audio signal processor or a stand alone noise maker. this unit makes screwed up sounds nasty ones. you will get nothing musical from this machine so if you dont like harsh wierd sounding stuff please dont buy this. if you are a normal person probably not for you. but if you are into mayhem and ruckus check out the video and pictures. it has ON THE LEFT SIDE THE SYNTH SECTION VCO1 LFO1 LFO2 EACH HAS AN TOGGLE ON OFF. THE TOGGLE THAT IS UNDER THE VCO TURNS ALL OSCILATORS OFF WHEN DISENGAGED THE VCO IS THE MAIN PITCH. THERE IS ALSO A MOMENTARY PUSHH BUTTON FOR SHORT BURST OF SOUND THERE IS ALSO A MUTE BUTTON FOR STUTERING THE SOUND OF THE LEFT SIDE OF THE SYNTH. EACH OSCILATOR HAS KNOB TO CONTROL RATE.
ON THE BOTTOM RIGHT THERE IS A VOLTAGE STARVE THAT EFFECTS THESE OSCILATORS. ABOVE THE OSCILATOR SECTION IS FIVE TOGGLES EACH ONE IS AN OCTAVE MODULATOR. TO THE RIGHT THERE IS A SCUZZULATION EFFECT THAT HAS ON OFF AND FIVE MORE OCTAVE TOGGLES ABOVE IT. THIS CAN EFFECT SOUND COMING FROM THE SYNTH SECTION WHEN NOTHING IS PLUGED INTO THE AUDIO INPUT . IT HAS AUDIO INPUT AND OUT PUT ON THE BACK 1/4INCH STANDARD. ON THE TOP IS THE MIXING SECTION THERE IS A CLEAN VOLUME FOR THE AUDIO INPUT AND THERE IS A VOLUME FOR THE SCUZZULATION AND THERE IS A VOLUME FOR THE SYNTH SECTION.
