Sequential Circuits Studio 440

“This 440 is in great shape Its very rare to find one in this condition. The pads are still bouncy and intact. The knobs are not loose the data slider is still tight. There is a small slight blemish on the top right of the disk drive (as shown in photo) but other then that it is in great shape cosmetically (as shown in photos) This unit was just given a clean bill of health from the Sequential Circuits expert Greg Montalbano from Analog Synth Service in Berkeley and is ready to report for duty.” Click here to visit listing on eBay

Sequential Circuits Prophet 2002 and Sequential Circuits Prophet 2002 Plus

“This listing is for a Sequential Circuits Prophet 2002 Plus and a standard version Prophet 2002. The Prophet 2002 Plus is working and has the rare 1 meg expansion kit installed. 1 meg might not seem like a lot but it makes a big diffence from the standard version. The standard Prophet in the listing is not working, it turns on but does not have a disc drive. It is being sold as is, for parts. I took pictures of both with the top open to show the condition of the components. You will receive both Prophets, original Sequential 2002 manual and 2 Sequential pedals.” Click here to visit listing on eBay

Sequential Circuits Pro One

“This SCI Pro One is in excellent condition. It’s fully functional and sounds great. It was recently serviced and is ready to go. All keys trigger properly, pots are clean and switches all working. This is the more desirable J-wire keyboard version. This is a classic awesome sounding mono-synth. Also included is the MTG Turbo Kit (not installed). If you would like our techs to install it we can do that for actual cost, estimated 2-3 week turnaround. Estimated installation cost $300 but this is just an estimate. Message us if interested in having the MTG Turbo kit installed. ” Click here to visit listing on eBay

Sequential Circuits Prophet 2002

“Sequential Circuits Prophet 2002 sampler with analog filters, good shape, has assorted wear and scratches (see pics), but operates fine. Has had the floppy drive replaced with a gotek usb drive floppy drive emulator, and includes a usb stick loaded with samples. Has 4.3b os, 246k memory, originally was 128k but I added an expansion board. Comes with an original copy of the manual that includes two sample floppies. Also included is a selection of replacement chips: one cem3379 vcf/vca, one I-624 custom voice ic, and one 256 ram chip. Two of the original knobs have been replaced with P600 style knobs, as I could never locate any of the correct ones, and the rack ears have the edges broken off, but still work fine.” Click here to visit listing on eBay

Sequential Circuits Pro One

“Legendary analogue synthesizer from 1981. Without a shadow of doubt the most powerful mono synth ever produced. This thing is completely devastating for bass, but also excels at leads, drones, percussive sounds and all kinds of other complete madness. A truly wild and amazing instrument. The real deal – none of this modern clone/reproduction business.

This one has the much more desirable J-Wire keyboard – and is serial number 6732. A bit of research online will reveal that this is what you want – the first couple of thousand has problems with the internal power supply and the ones after 8000 had the badly designed membrane keyboard. The synth was serviced a couple pf years ago and is working flawlessly (I can provide the service invoice). The synth is in immaculate condition cosmetically. Wooden end cheeks are in really nice condition. All in all for a 40 year old unit this is a really incredible example. An amazing and inspiring instrument but also a solid investment, the price of these things is rising all the time these days.” Click here to visit listing on eBay
