I’m not a keys guy, but plugged in and all controls seem to work, all keys working, sounds good to me. Very clean cosmetic condition. Located in Columbus Ohio zip 43231, local pickup would be fanstastic ….” Click here to visit listing on eBay

“Serviced and appears to be fully working. Shows very little signs of use. Fantastic sound and an overall gorgeous instrument. I’ve priced this at the lower end of what these sell for and considering average completed sale prices, the service, and physical condition, this is the lowest I will accept and I believe it represents a fantastic value on a highly appreciated vintage analogue synth.”

“Offered as-is, the Sequential Prophet 600 is a classic 6-voice polyphonic synthesizer with some issues: it has tuning stability problems and the LFO is misfiring, resulting in a persistent LFO/modulation pulse across every preset. However, the keyboard is fully operational, with all keys and the program section functioning correctly.” Click here to visit listing on eBay

“The Prophet 600 is a good synthesizer, but with the GliGli CPU upgrade installed it becomes a great synthesizer! One of the best vintage synth values out there today.

This Prophet 600 is in good working order and has been upgraded with the GliGli mod running the 2.0992 firmware revision (GliGli’s final version), a new membrane panel, a new set of Synthchaser key contacts, and a new set of knobs. All 6 voices are tuning, scaling and sounding great.

Very good physical condition, some wear/chips on the side panels (see photos).”

“This is the second 600 I’m selling, part of a collection that I’m selling; as with other pieces, this has been in storage for a long time, therefore requires calibration, new battery and inspection by tech. The good news is no one‘s used it for a very 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 ways they differ, both having pros and cons. Very nice piece that comes with flight case, manual.” Click here to visit listing on eBay

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

“This 600 comes with Fatar keybed and new wood ends and overlay. Comes with power cord, GLIGLI and the leftover electronics if you want to switch it back to the original. the GLIGLI mod opens it up though. Super clean 600.” Click here to visit listing on eBay

“Sequential Circuits Prophet 600 with GliGli

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. It comes with factory MIDI for external control and has been upgraded with the fabulous GliGli mod (currently running v2.0 although this can be easily updated to the more recent v2022). This upgrade greatly expands the functionality of the synth and full details of GliGli V2.0 can be found here –

The keyboard is being sold as is for parts or repair.” Click here to visit listing on eBay

“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

“WORKING CONDITION: Excellent – Works great. This Prophet 600 has the Teensy ++ Gligli mod which simply improves the MIDI features and overall sound of the Synth. All of the keys are responsive. Each control and parameter is working properly as well. In all, everything is fully functional and in excellent working condition.

PHYSICAL CONDITION: Very Good – There are some scuffs and abrasions mainly on the wooden side panels of the synth. Otherwise, everything is solidly built, intact, and in very good physical condition.

” 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
