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
