Sequential Circuits Prophet 5 Rev 3.3

“Vintage Prophet 5 Rev 3.3 Flawless W Case storage find

I am a collector over decades; only kept best condition gear. I have decided to sell part of my collection.Anyone interested in a classic Prophet 5 in the best possible/ridiculous condition pls take a close look at pics… All of my gear including this has been in storage for decades and looks similar to the day it was originally bought. No issues whatsoever; tuning is very stable.

I wasn’t actually planning on ever selling this but life changes. It’s absolutely flawless physically, is the last rev which means it’s the most stable and yet sounds incredible. It does not have midi but I also have the best possible Kenton midi kit available to install on it if that’s of interest.”

Sequential Circuits Prophet 600

“Sequential Circuits Prophet 600. Currently in stock configuration but can be supplied with or without GliGli mod, latest update and patch set – contact me to discuss details

I’ve owned this beast of a synth since the late 90’s and had it serviced around 5 yeas ago before putting it in storage for safe keeping. 

Perfect working order and v good aesthetic condition (some minor wear and tear on chassis and wooden end cheeks – please see the photos).

I have the GliGli CPU upgrade configured and ready to be installed but have left it in original configuration so you have the choice of experiencing it as it was setup in the factory but can have GliGl mod installed before sale if required and/or can supply the upgrade parts in a separate package so you can install/uninstall it at your leisure.”

Sequential Circuits Prophet 600

“Sequential Circuits Prophet 600.

One owner (me!). Includes power cable, original manual, original sound tape + 2 backup tapes. I have replaced the battery within the last 5 years but I couldn’t for the life of me tell you exactly when. Keypad works, knobs work, Pitch wheel & modulation wheel work….everything on this keyboard still works. Despite the scuffs on the wooden end pieces, the machine is in great shape. I tested it in May before I relocated to another state and it worked as it should. Unpacked in June and couldn’t locate the manual. I didn’t want to sell it without that and it has taken me this long to locate it. Lucky storage box search yesterday! So I’ve not tested it since May, but it has been sitting safely on a bed awaiting the manual. ” Click here to visit listing on eBay

Sequential Circuits Six-Trak

“Sequential Circuits Six-Trak Synthesiser 1984.

This unit is in great condition and works as it should. Sadly the internal battery died so the synth is not storing patches or doing anything interesting other that powering up. Played fine when last used few months ago.

The battery is soldered in but could be replaced with a battery holder . Cheap easy fix, low bargain price. 100 patches can be reloaded via SYSEX bank dump as I have done in the past.” Click here to visit listing on eBay

Sequential Circuits Prophet 2000

” Sequential Circuits Prophet 2000 Keyboard Sampler

Reluctantly selling my Prophet 2K, the classic 80’s sampler that along with the Ensoniq Mirage ushered in semi-affordable studio-grade sampling for a much broader range of musicians, and helped give birth to House Music, and Electronic music as we know it. Serviced a year ago (I’ll include the receipt, £160 spent with a top tech) and not used much since, I just don’t have the space to set it up these days, so it’s annoying my wife in the spare room. Almost worth keeping for that reason only but best to try to score some brownie points before Christmas.

It’s fitted with the excellent 2x Memory Expansion by Synthechnics (cam reform Portugal, another £100 or so), which is a modern reliable clone of the original SCi one. Membrane buttons, wheels, dials and all keys work great, with display bright and clear. In fact the tech thought that the tact switches under the membrane may all have been replaced at some point pre-me, which is a handy bit of future proofing I didn’t realise (although they always felt surprisingly good). Quite a few age-related marks and scratches here and there on the bodywork, and that’s just a bit of old tape residue on the back corner that may well come off with a bit of perseverance, but no scary damage, just a nice honest example. It comes with the UK power lead, plus the original Operation Manual, which is a rare thing, a chunky ring-binder file. Latest/last OS version chip installed too.

These are coming up for sale less and less often, partly due I’m sure to videos by Espen Kraft and others showing what these are capable of, and what they can add in a modern studio setting. So a serviced one with memory expansion and the original manual file is a rarity. I can’t see another P2K available either on reverb or on here right now in the UK, or anywhere in the world for that matter.” Click here to visit listing on eBay

Sequential Circuits Pro One

“model # 100, serial # 2330

This Pro One is in perfect working condition. It was calibrated and it’s J-Wire keyboard was rebuilt several years ago. I bought this synth in 1990 when people were dumping analogue synths. Since that time it has been taken very good care of. When not in use it is always covered. This Pro One is missing two of its four rubber feet. This unit was in a stand so it was never an issue for me. I am selling this unit to fund purchasing some eurorack synths. I own another Pro One I bought in 1981 and a newer Behringer Pro One. ” Click here to visit listing on eBay

Sequential Prophet 600

“This synth was recently serviced by Wine Country in California and is working very well! All functions are working as intended. A brand new membrane panel was installed so all pushbutton keys are easy to press and reliable. The synth was fully recapped.

The key bed was also cleaned and all keys are working well with minimal dropped notes as long you don’t play with a very light touch.

A print out of the manual / service manual is included in a binder, along with the Wine Country program patch cassettes and the original faulty parts they pulled, along with the original CPU chip that can be reinstalled if you would prefer to revert the Prophet 600 to a non-gligli “stock” condition.

The synth will be packed very well and will ship with full insurance.”

“This
Sequential Circuits, Phophet-600, Original MIDI,
synth has seen many days on the road,
and has a broken “A” key that can be replaced for about $15 overseas,
all original equipment from 1982…

The sounds from this unit are the same sounds you get from the original Prophet 5, but under MIDI control, for complete freedom of expression…

This synth comes WITH the heavy-duty road case for secure travels, and shipping…

I don’t have the time or money to work on this anymore…

I will supply you with the technical manual for troubleshooting problems…

All the parts are there, it just stopped working, and I don’t have my test equipment anymore…

Thank for taking this off my hands… :)” Click here to visit listing on eBay

I’ve owned her since 2012 and barely touched her. She has been fully serviced in preparation for sale, with the latest GliGli patch and Luke Neptune Prophet 600 patch pack installed.

Perfect working order and good aesthetic condition (the odd scratch and a chunk out of one wooden cheek – please see the photos). My tech replaced an encoder pot and likely forgot to cut the post down – so that knob sticks out a few additional mm compared to the others.”

UPDATE 8/28/22

Been getting alot of questions so I took more pictures. This is my Pro one. Bought it new in the 80s at Sam Ash in Queens NY. Used it a few years at home only. It has been unused for over 30 years in storage at different locations. When I used it, it always worked. Looks like the fuse has fallen out and I don’t have another or know when it was lost. I’m assuming that’s all it needs but not sure” Click here to visit listing on eBay
