Roland TR-707 Project Machine

“Up for sale is a used Roland TR-707. Has issues and is heavily used but has been a workhorse for years and years. Blue tape is to keep batteries in so the memory doesn’t erase itself.

Issues: Both the Headphones and R (Mono) L outputs have a static sound that is noticeable when drum sounds aren’t engaged, and engaged but static level drops down once drums are playing.

The individual outs for each sound work (except Ride, which works only on the Headphones and R/L outputs) with that static noise gone, and that is how i’ve used it for years.

I have programmed beats on it for years, but never used the midi or song parts of it, but would assume it works. Usually just recorded a beat and switched between patterns while jamming, and it saved just fine.

Missing Tempo knob

No power supply for this one — have always used a generic 9volt supply, which is easy to find.

Selling for cheap and AS IS / no returns due to these issues. “ Click here to search for synths on eBay

Roland Juno 106 Project Machine

“This is a vintage Roland Juno 106 that works, but will need some repair for it to function normally. It was pulled out of my brothers storage space after many years of idleness. There wasn’t a power cable with it so I had to buy a special two prong cable that it needs. I’m not a synth wiz but I’ve done the best I could to describe the problems below!

It seems like these models have a known “voice chip” problem. I’ve noticed that the first 4 voice chips seem to be working and the last 2 of them are not, simply because the first 4 notes played will be heard, and the next 2 won’t. The pitch bender feels a little loose in the spring. It bends down and springs back up on its own, but when bending the pitch up it tends to slowly come back compared to the former, which comes back up immediately. Both up and down DO work though whether you are using it for pitch or for the filter, but I noticed that I couldn’t get any LFO sounds when pressing the wheel forward. The LFO though seems to be working fine when I put it on the automatic setting. My guess is that the spring in the pitch bender needs replacing since it does feel a little loose.

All the keys tested fine and activated (accept when there was a bad voice chip about to be played obviously!) both chorus settings worked, as well as the oscillator, frequency, and ADSR sections. Basically all the sliders and buttons made a difference when adjusting them. The presets work too. Cosmetically it doesn’t look too bad at all for how old it is and I think it still looks pretty nice!

I am not sure how much work this will require I’ve done a little research about these in order to gain some knowledge for this listing but again. I’m not an expert by any means, and even though I’ve gone through all the different functions as best I could, and I want to be clear that there could possibly be other issues that are just not apparent to me. So with that being said this is being sold as-is for repair/ working parts only and no returns. ” Click here to search for synths on eBay

Korg M500SP

” The Korg Micro Preset is a small simple 32 key single oscillator monphonic synthesizer manufactured by Korg from 1977-1980. It features 6 presets that can be modified with limited on board controls such as a simple Attack/Decay envelope, an assortment of knobs for real time editing, an LFO and sliders for filter cutoff and resonance. It is said to sound very much like it’s elder siblings in the MS product line It is also a circuit bender’s dream as well as a mod maker’s. 220V.” Click here to search for synths on eBay

Korg Polysix Project Machine

“Korg Polysix Analog Synthesizer with Flight Case

Please note that the battery has leaked and refer to the photographs. Ships to the lower 48 States Only.

This Korg Polysix powers up and the keys respond but I am uncertain if it is in tune. The notes seem to go up and down the scale. I listened on headphones and also ported the audio out to a keyboard speaker. I noticed several pots were scratchy and/or intermittent so this synthesizer definitely needs servicing. I have not tested the presets as I don’t know how.

This synthesizer is not fully tested as I don’t have the experience nor the expertise. Outside of this basic test no further testing has been done so this sells as is with no guarantee and no return. Sells For Parts or Not Working. This Korg Polysix is cosmetically acceptable, please refer to the pictures. The flight case is in acceptable condition as well.” Click here to search for synths on eBay

“YAMAHA DX100 SYNTHESIZER in Good Condition. All functions, buttons, keys, inputs and outputs work properly. I am the original owner. It has never been outside of my professional studio.

All sound waves are programmable so skies the limit. There are a couple of minor cosmetic scratches but they really aren’t very noticeable. It is truly a powerful, rare synthesizer with unique sounds and portability. Includes AC adapter and original manuals.” Click here to search for synths on eBay

It’s got some really nice custom made looks like birch ends. This is the Japanese 100VAC version but the studio I got it from insisted they always used it at 117VAC without issue.
