“This TR-909 is fully functioning and ready to change hands. The screw mounts for the left side panel are broken and I’ve used tape to keep it in place over the years. It came this way from the previous owner and although OEM side panels can be cheaply sourced from a Roland SBX-80 or custom built wooden ones would work all the same, tape worked just fine for my purposes. To be completely thorough the individual outs are not fully volume consistent, adjusting the gains on the mixer channels to match desired levels (or the volume pots themselves) is necessary. This is true of vintage analogue drum machines in general and comes down to personal mixing preferences. This is a non-issue function wise with the TR-909 itself.

“Prophet 2000 in excellent condition, fully working. Installed USB, firmware V3.0, extended memory.” 
“PHYSICAL CONDITION: Good – There is a 4″ strip of wood missing from the top part of the right side panel. There are light scratches and scuffs all along the sides of this synth. All the LEDs light up as they should. All the pots rotate nicely. The master volume pot/knob wiggles slightly from side to side compared to the other knobs. All the push button feel good and the I/O jacks on the back are solid. The keybed’s fast, light action feels great and the keys are level with each other. All the keys are fully intact with no major chips or cracks to speak of except for the Bb/A# key to the left of the middle C which has an extremely small blemish near the middle. The power cord is in great shape with no tears to speak of. Overall, this synthesizer is in good physical condition WORKING CONDITION: Excellent – Works like a champ! All keys, all control knobs, all buttons, all LEDs, both pitch and mod wheel as well as all I/O are working perfectly! Overall working condition is excellent”

“Rare Zorlon Cannon MK1. Pitched noise and pseudorandom gates in a compact package. Perfect working order.” 
” original Mk1 Maths with evil red LEDs. Minor rack rash and some small hairline scratches, otherwise cosmetically perfect.
“I really don’t know much about this keyboard, so ask questions before bidding and I’ll try to do my best to answer! You are also welcome to visit and try it out in person! I consider it to be partially to mostly working, I did try a number of the built in sounds and they seem to be working fine but some of the keys produce less sound and sometimes very little to no sound so I think they’ll need some attention. Battery warning comes on when you turn it on so it will need that replaced. I did not test any of the other various memory or other functions, only a basic test. Metal case in good shape, a lot of the lettering on the cabinet is quite worn but in general I’d say it’s in good condition or better cosmetically, no damage or signs of abuse. 2 screws are missing on the front. Comes with a nice fitted soft case, stand, original foot pedal, power cord, USB to MIDI cable and the 2 cartridges (which are untested) pictured, Music Pack and Q Spectrum. ”

“P9700S Series Analog Modular Synthesizer. This is a set of modules that form a complete system in a 19” rack case. Sold by PAiA as a DIY kit, this one is fully assembled (seemingly a long time ago). It’s listed as “for parts or not working”, but it actually does work. It is quite worn. The surface has some scratches, labels of controls are hard to read. Some of the cable connections feel loose. All of the modules can be calibrated, and they probably need calibration. Every connection and knob does at least work, but I’m not sure the performance is 100% accurate.” 
“Great condition only used rarely in studio environment, fully operational, minor rack rash.” 
“Vintage Octave Cat SRM Synthesizer. Condition is For parts or not working. Listed as such because we dont have proper equipment to test really. Found in attic. Powers up. Body is clean and has all knobs. Tried taking it to friends house to test with cords and amp but not sure we hooked it up right or adjusted properly. All knobs seem to make sounds change, and at one point we got the keyboard to work ( kind of) but not sure how and then we couldnt get it to work again. Sold AS IS.” 
“Up for sale is this amazing vintage, rare 1980s Moog Opus 3 analog strings/brass/organ synthesizer. Synth is in overall good condition. All keys play and everything seems to work, the only things I’ve noticed is the “right” output in stereo mode cuts in/out, but could be an easy fix – mono mode works great. A few of the sliders are a bit finicky, but may just need some cleaning. Comes with the power cord.”
