Sequential Circuits Six-Trak

“This is a joy to own but alas I cannot do it justice. Classic sounding from a time long long and they do not make them like this anymore. Studio use only and recent repair and upgrade.

Looks great with the odd mark and scratch which is to be expected. power is direct from the back to the plug. I have also printed out most of the manual (it is not the original). The joy of playing this is that it is 6 Note poly which was a rarity back then. Most of the tech spec is on line but if you are looking at this piece of history you will know all about it anyway.” Click here to visit listing on eBay

Sequential Circuits Pro One

“Sequential Circuits pro one.

I bought this fantastic sounding mono synth about 20 years ago second hand.

The power cord is somewhat frayed where it meets the machine, but this causes no problems as yet in turning on the machine.

Also, the keyboard has some dust in it meaning that sometimes, if pressed hard some of the inputs on some keys stutter, due to the electrical connection.”

(However owned it prior to that took exceptional care of it.

The unit was not working and I held on to it since then. I decided last year in March to have it repaired. It would light up but not boot to program mode. I sent the unit to one of the absolute best technicians possible for this type of instruments. The unit was sent to David Sesnak of Wine Country Productions in San Jose, California. He could not believe how great the condition of this unit was cosmetically. All repairs he made totaled $746. I had him install the GliGli update as well.

The wood sides are original. I’ve included the invoice of work performed. I could not bring myself to discard a vinatge piece of music history so I am offering for someone to enjoy for years to come. Buy pays actual shipping costs. Package is 31lbs and dimensions are 51L x 25 W x 8 H. Unit will be professionally packaged.” Click here to visit listing on eBay
