Roland Alpha Juno 2

“I have added custom blue LED underkey-lighting making it stand out at dark performance locations.
While exchanging the 40-year-old LCD display for a bandnew OLED display I’ve upgraded the ROM and installed a new backup battery.

From my tests all functions seem to work as expected. The pitch/modulation joystick is a bit tight, but works. Some buttons on the editting pad need a little more pressure, but also work.

Comes with a US-standard plug, stated input is 100-117 Volts AC.
The original sheet music holder is included. No user manual included, but can be found for download online.

Made in Japan, 1985.” Click here to visit listing on eBay

Korg Polysix

“The Korg Polysix is an all-time classic, highly-sought after analog synthesizer. This unit is clean and in great condition, with no broken or missing keys or buttons. It does power on – however, it suffers from the same problem that nearly every Polysix was affected by, which is that the battery on the KLM-367A board leaked and damaged nearby traces and components. This synthesizer did function when I first acquired it in the early 2000s. However, at some point the battery issue did cause it to cease working properly.

Repair was attempted on this synth: The leaky battery was removed and a new battery as well as IC chip and socket were installed. However, that didn’t solve the problem. Someone knowledgable about this issue should be able to repair this keyboard, or install a new KLM-367A board and have themselves a wonderful vintage analog synth.”

“This is fantastic combo setup consisting of the famous TX7 (an improved real DX7 engine (no modelling) in a small package) and its partner, the DEP-3 reverb. I also include audio and MIDI cables to get you started playing this setup from any MIDI keyboard (or other controller). Initially, the new owner can connect everything as shown in the photo, connect the DEP-3 output to a mixer, audio interface or amplifier without moving any other knobs, and dial combination 11 on the TX7 as shown to get a beautiful “baroque” patch used during testing of audio output. Both units are North American 120V models with power cables included.” Click here to visit listing on eBay

Sequential Circuits Drumtraks

“This item is being listed as non-working/for parts simply because some of the pads are not as responsive as they should be (most notably the RIM pad & the # 6, 8, 9 & left arrow on the number pads. However, you can still get around and create within this machine with ease.

I am not by any means an expert in these machines but having owned an E-MU SP 1200 (the pads are similar) possibly the pads may just need to have the contacts cleaned. This machine fires up without any issues. All the outputs are working properly and sounds amazing. The faceplate has a few blemishes but still shows rather nicely. This is your chance to own a legendary piece of equipment in which was used on timeless classic recordings by Prince, Freddie Fresh, Orbital and many others.” Click here to visit listing on eBay

item is sold AS-IS as described i am exposing the flaw and it cannot be returned. NO REFUNDS NO RETURNS as the freight is a killer this is a heave one.

LinnDrum LM-2

“For your consideration, we have a serviced LinnDrum LM-2 that includes the midi upgrade, installed by J.L. Cooper. The unit comes from a private studio of a colleague of ours who uséd in on many recordings. It had not been uséd for some time, so we did a deep clean on the unit, and then ran the unit. It worked, but there were some sounds that were not working, and some of the pots and faders needed cleaning. So, first off we checked all pots and faders, and serviced them. All socketed chip contacts were cleaned. As mentioned, there were several sounds not working, which we traced to faulty microchip U87. We installed a socket and new chip, which solved the issues. The unit’s power supply was fully recapped, and a new battery tray with rechargeable batteries were installed on the auxiliary board. The original side panels showed some wear, so we fabricated new ones. The unit is now fully functional again, and needs to be put to work by the next owner.

The unit has 11 Zif quick-change adapters installed on the board sockets to facilitate swapping eProm sound chips for the following sounds:

Conga 1, Conga 2, Tom 1, Tom 2, Sidestick, Snare, Tambourine, Cabasa, Claps, Cowbell, and Bass

Physically the unit is in very good condition for its age. There are some light scratches on top, and some spots and blemishes, but no dents or signs of abuse. Overall the unit presents itself very well. See pictures for further details on the inside, and outside of the unit.

We don’t have the original box for this unit, but we take packaging and shipping seriously. We spare no expense and use heavy duty boxes, several inches of polyethylene foam on all sides of the unit, and use water activated, fiber reinforced tape on all seams.” Click here to visit listing on eBay

Roland Juno-60

“Roland Juno-60 Keyboard Synthesizer

Excellent vintage condition – gently used in a studio setting many many years ago. Unlike, other units, this piece has been sitting in storage in a flight case. I parted ways with my studio environment back in 2008. The Juno has been sitting in my storage for over a decade and hasn’t been used ever since. Smoke-free environment, kept in a cool air-conditioned storage space. As you can see it’s been sitting in its flight case for many many years aging like fine wine, well sort of. Unfortunately, it’s time for me to part ways with this piece of history and for it to find a new loving home to rock the airwaves. ” Click here to visit listing on eBay
