Quasimidi Sirius

“I’ve owned several of these in my career but this one is in the best condition I’ve ever seen. Obviously it is used but if you opened it back in 1998 you’d be hard pressed to think it isn’t new. It comes with the original US power supply, original mic and full manual. It will be shipped in pristine condition with lots of love and insurance, shipping only to the continental US please. This has features no other board has. You can easily create a random patch, throw it into the sequencer, twist the waveform as it grooves and so much more. If you’ve always wanted one of these but wanted it in the best condition possible, this is your chance. Thanks for looking. ” Click here to visit listing on eBay

PAiA Modular Synth Cabinet

We normally deal in meticulously serviced high value items. This item is of relatively low value and has not been given our typical treatment, as this would be cost-prohibitive. It is however described to the best of our ability below:

Our tech tested this and says the watt blocks are putting out the right voltage. Some of the wooden pieces in the back that the back lid screws into may need to be fixed or replaced if you want to put screws in all 4 positions. When this unit is powered up, the right LED lights up. The left one doesn’t. We normally refurbish our gear, but this is a low value item not worth paying our tech to work on, so we’re selling it as is. ” Click here to visit listing on eBay


“We meticulously restored and improved this unit to make it better than others you may find on the market. This required approximately 25 hours of skilled labor, which is of course reflected in its higher than usual price. You get what you pay for. This unit was 240v when we got it. We switched it to 120v (US voltage) and replaced the power cord. All pots were cleaned and lubed, and a few had their carbon elements replaced since we couldn’t find entire drop-in replacements for the original pots (if anyone has a source for them, please let us know). We replaced all CD4051 CMOS chips as a preventative measure. Cleaned unit inside and out. 4 sockets were replaced. Replaced battery. After replacing the battery, the internal patch memory is empty and ready for you to program new sounds into it (or reload originals, if you prefer). OSCars have a bad rep for being unstable. Most importantly, our tech performed his special custom modifications to this unit that should make it much more reliable than other Oscars you may find elsewhere. ” Click here to visit listing on eBay

Moog Minimoog Model D

“The unit is still in good condition, it still even have the factory plastic cover on both the control plate and pitch/mod plate.
I tested all the functions and they all work, but probably will need some calibration on the inside trim pot.
The unit is configured to take 220V wall voltage, you will need to make adjustment on the mains voltage select if your country is not 220V.” Click here to visit listing on eBay

Roland Promars MRS2

“It is maintained by a professional, and there are no operational problems such as pitch tuning, sound output from all keys, preset tone switching, and VCO, VCF, LFO, EG in manual mode.

The built-in battery has not been replaced. You can save the tone by replacing the built-in battery, but the battery is not replaced because there is a disadvantage that the saved tone cannot be edited. It’s a fun instrument to use while moving the knobs in manual mode.” Click here to visit listing on eBay

Blue Roland SH-101

“We are pleased to offer this excellent rare blue Roland SH-101 Synthesizer with original box. It is in great shape for being nearly 40 years old. One minor scrape on tip of one key (photo) and a missing screw on the bottom (no photo). Battery compartment clean and fully tested and works fine with batteries. Slides/pots may need cleaning, but certainly sounds like it is working okay to me, though not an expert. Watch video (cut & paste link below) to hear it play. Cat stays! I am missing the Mod Grip and the original power cord. I do have a radio shack 9 volt with tip – power supply that I will include (also tested). Box is in great condition with original styrofoam.” Click here to visit listing on eBay

Yamaha RX7

“Brilliant condition for its age with just a couple minor issue that can be easily addressed .

‘Data’ slider knob is missing. The ‘key assign’ and ‘cassette’ button don’t respond unless you press them a handful of times. This indicates to me that they simply need opening up and cleaning which would be an easy fix. Has a few marks and a small crack on screen by the ‘effects’ light indicator but is expected from its age.

Apart from that, the drum machine works brilliantly and can be hours of fun if you have a good look through the manual 🙂

Comes with brand new power adapter” Click here to visit listing on eBay

Yamaha FB-01

“Here we have a Yamaha FB01 which is a late 1980s FM based midi synth. It’s in great shape. I have the manual too.

It is 8 note poly and those voices can be used as 8 different mono sounds, a single 8 note poly or a number of other splits… (For example, 2 mono sounds, a duo sound and a 4 note poly sound(

It is the absolute classic sound of mid 80s. It is a simpler version of the classic DX7 (which is not multi timbral) with 4 operators.” Click here to visit listing on eBay
