Sequential Circuits Pro One

“Up for sale is a highly modded and amazingly cool Sequential Circuits Pro One.

This synth is modded. Keyboard is an entirely rebuilt J wire keyed… not the horrible membrane version. The serial of this synth lands in the membrane keybed version but a J wire keyed was overhauled and installed. It plays and tracks extremely well. No double triggers or mis-triggers. It also has an aftertouch strip put in. The key dip is just a tiny little bit less, and there is a pic showing that. The keys goes down a little more when you activate the aftertouch. Very light and quick action. The aftertouch controls many things. Pitch up and down, modulation, LFO, Filter, etc…Very flexible variations. Also there are two pots inside the synth for gain functions for the aftertouch if needed. There is an additional LFO pot added , and there is duel portamento pots for the two VCO’s . Very effective on glides rather than the stock single portamento . Also a momentary jack in the back for on/ off portamento. Again a very effective performance feature. Tested , and everything works as should. In tune and calibrated. Ground loop issue corrected, which was common for these keyboards. Condition is good. There are a few marks on plastic and some marks on the keys. But its all minor… jut=st stating for full discloure on this ad. The only thing to note is that the Master Tune pot shaft has the tip broken off. You can still easily use / adjust it. With all the mods completed, this takes the Pro One to a whole new level. Ive created some very wicked efx, basses, leads that simply cant be done on a regular pro one. GREAT synth, great condition, great price. ”
