Sequential Circuits Prophet 600

I am selling my Sequential Circuits Prophet 600 6 voice analogue Polysynth.

For an instrument that is 40 years old it’s in excellent condition and sounds fantastic. Everything functions as expected.
“It has the GliGli mod installed and is running the latest (V2022 by Imogen) firmware which is running flawlessly. This new firmware brings a heap of functionally to the synth including an LFO with a much wider range, different LFO shapes, you can dial in different envelope behaviour, etc. More info on this can be found from a simple internet search. Alternatively just ask me and I can give you more information if it’s helpful. These improvements bring this into line with more feature laden poly synths and make it a very versatile instrument while retaining an easy and intuitive workflow.

I have had the cheat card printed. This makes implementing the new GliGli functions simple and straight forward.

When I purchased this from the previous owner they listed it as having been serviced. I don’t have any of the details of the service but given that it’s had the Teensy mod fitted this would suggest that other aspects of it will have been serviced. I appreciate that’s not particularly concrete but I want to be completely transparent with the information in the listing. What I can say is that everything functions as it should with the membrane panel working perfectly, and all keys and pots working as you would expect them to.

This synth genuinely sounds fantastic, alive and expressive. It has been my favourite sounding analogue poly that I’ve owned by a mile. I am only looking to sell it as I’ve just got hold of its big sibling the Prophet 5 and there’s so much cross over in terms of sound and function that I can’t justify keeping both.

It comes with a US plug hardwired but I will include a transformer that will allow it to work on UK power. I have enquired with several synth technicians in the UK and it’s apparently possible to change this to a UK type plug. I’ve never felt the need to do so as it works flawlessly as it is.

It also comes with a Thon hard flight case which the prophet fits snuggly inside of.

I have also had the manual for the latest GliGli firmware printed and bound professionally which I will include” Click here to visit listing on eBay

Classic 6 voice analogue polysynth. This synth is capable of a diverse range of warm analogue sounds, from soft pads to fat basses and everything in between.

“For Sale is an excellent condition Sequential Circuits Prophet 600. I am the original owner, and will ship the keyboard in its original box, with the original foam mold packaging.

I never used this keyboard much, as I am more of a pianist and bought it for a band that didn’t end up lasting. It was stored for most of its life in a temperature controlled storage unit. Several months ago I dug out many of my old synthesizers and organs (mostly for nostalgia’s sake) and decided I was going thin out the collection.

The keyboard was refurbished this past September by one of the premier Synthesizer repairmen in NYC. I put about 1100 into it, if you are interested in what he did, I can forward you the email he sent me itemizing the work done.

This is a great keyboard, and if I had more space I would keep it, but it’s down to this or my original arp odyssey, and that has always had a special place in my heart.” Click here to visit listing on eBay

“This is part of the collection I’m selling; as with other things, this has been in storage for a long time. It therefore requires calibration, new battery, and inspection by tech. The good news is no one‘s used it for a long time, so you’re getting a very clean unit. As an owner of Prophet 5s, I can say this is quite comparable in many ways. In some other ways, they differ, both having pros and cons. Very nice piece comes with flight case.” Click here to visit listing on eBay

Sequential Circuits Prophet 600

” Sequential Circuits Prophet 600 – Vintage Analogue Poly Synth – s/n 3660

An absolute classic poly synth from the 80s.

This one is in very good condition, not perfect, but very good. And it’s all working well.

There are some minor marks here and there which are to be expected from a synth of this age that has been used. Some little chips to the paint that have been coloured in (not by me) which show up when you look carefully. There are some minor scratches on the front panel but they are not glaringly obvious and a few marks on the top keys which might come off. The membrane panel is very good with no damage at all, and I have had no problems using it. There are a number of quite obvious scratches and marks on the bottom of the synth most likely from being on a stand.

The knob caps are all good except for the speed control (on the membrane panel section) where the white mark has faded. Everything functions as it should, buttons, switches, knobs, led display, keys, midi, etc.

The wood end panels have been replaced as the original ones were pretty worn. The new ones are thicker and look really great. I will include the original ones so you have the option of going fully original if you want.” Click here to visit listing on eBay

“・Noise can be used without sacrificing the waveform.
・There is a keyboard with poor response.
(It may react if you play it several times.)
・The movement of the left side of the wheel controller (pitch bender) is a little stiff.
・There is a big chip on the right side wood.
・There are scratches and scratches appropriate for the age, but it can be said that it is reasonably good except for the chipping of the right side wood. (This is subjective)” Click here to visit listing on eBay

“Sequential Circuits Prophet 600 with gligli upgrade in full working condition. Amazing sound and the v2022 gligli firmware update turns this 600 into a hefty Prophet 5 contender. More routing options, more LFO and lfo routung, Prophet 5 type envelopes, “rebounce” that prevents double triggering, more stability, better tuning and so much more! The overlay on the left side of the data membrane panel is for gligli 2.0 but will send a manual of the v2022 update that explains all the routing, operation and execution of all the v2022 functions… that said, most of the text on the 2.0 upgrade is still as it is stated. Anyway.. the sound is massive and classic, everything works as it should.. this is a rare chance to get a classic with some supreme updates!!!!” Click here to visit listing on eBay

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.

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

“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.”

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…

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.”

“Fully functioning and restored – Sequential Circuits Prophet 600 Synthesizer Vintage Restored not Prophet 5. I am not a musician or a keyboard player. History of this instrument as I know it…This synthesizer has spent its life in a padded hard case. It was given to me by a co-worker back in 2013. He purchased it from Goodwill online. (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.
