Collector Grade: MXR Drum Computer + Custom Pelican Case

"This is a museum quality MXR Drum computer Model 185. It's been professionally stored in a custom Pelican Flight case (also included in the sale). At one point this was professionally serviced and fully gone through by Tech guru Jun, at Main Drag Music with the battery replaced. It hasn't been played in several years so a couple of the keys stick. If that bothers you then I'd suggest having a tech lube the contacts. Otherwise it works great and is cosmetically flawless. Those aren't scratches in the photos. A couple of stray hairs/lint seem to have floated into the shot. The individual outputs on this make it extra usable. I've had a lot of success running each sound to it's own guitar pedal or fx path for wild sounds."

Moog Multimoog SN 2395
Note: links to listings are affiliate links for which the site may be compensated.
via this Reverb listing
"Vintage Moog MultiMoog, one of the most expressive monophonic synthesizers from Moog’s classic late-70s era. Produced between 1978 and 1981, the MultiMoog expanded on the Micromoog with features like aftertouch, ribbon control, dual oscillators, sample-and-hold, and a powerful 24 dB/oct Moog ladder filter.
Condition:
Everything is fully functional – all keys, controls, and modulation options work as they should. It has not been recently serviced, so while it plays beautifully right now, at some point in the future it will likely benefit from a standard recap/service to keep it running at its best. Cosmetically very good for its age, with only normal wear. This MultiMoog is a rare find, offering the classic Moog sound with more modulation and performance options than most other Moog monosynths of its time. Perfect for both collectors and players looking for a unique vintage Moog with character and depth."

"This is a video I have made going over my personal Korg Polysix. After owning it for 7 years, I feel it is time to let someone else enjoy it and perhaps take it a step further in the restoration."

Bad Dog Designs OSPRAY 8 Drum Synthesizer
video upload by Pro Synth Network
"I have been very privileged to test, advise, and consult with Paul at Bad Dog Designs on this brilliant drum synthesizer. Taking circuit designs that were over 40 years old, published in E&MM magazine, Paul has recreated and refined these three drum synth designs to create OSPRAY-8, a "vintage" 21st century drum synthesizer.
Four drum modules, three cymbal modules and a clap module, triggerable via MIDI or CV and with a stereo audio output or individual mono outputs per drum, this is the sound of the nascent analog drum synth of the 1980s in a beautiful handmade case.
For more information and details on how to get your hands on one, contact Bad Dog Designs to register your interest.

OSPRAY8 Analogue Percussion Synthesizer Demos
video upload by Bad Dog Designs
"After about 4 months on and off, I've got my percussion Synthesizer in a state where I'm happy with the look and sounds :)
All original 1980's circuit designs with just a few component changes for later IC's, and of course Midi In and through as well as individual trigger inputs.
The OSPRAY-8 ( Old School Percussion Right At Ya! ) comprises 8 individual modules, arranged as 4 X Drum modules / 3 X Cymbal modules / 1 X Handclap module. There is then a final control module that handles midi, midi channel selection and Stereo output.
The Drum Module can generate a multitude of sounds from Bass drums to Snares, Toms, Rimshots, bleeps and other weird and wonderful sounds.
The Cymbal Module can generate Open and Closed Hi-Hats, Gongs, Cowbells as well as other metallic oddness.
The Handclap does as it says, but will generate multiple claps with full control of frequency / resonance / ambience etc.
As each module has it's own line out and trigger in, you can join two together, so you can combine a handclap with a drum and get a really sharp and punchy snare for example.
The front panel is machined from a single piece of aluminium, the lettering engraved into the surface for a well engineered finish. The Casing is still in development, but you can see a mock up in the clip.
All the audio is straight out of the OSPRAY-8 with no processing."
via Bad Dog Designs
"The Ospray-8 is a fully Analogue percussion synthesizer, housed in a free standing desktop format. The sounds are produced by entirely analogue electronic modules, tailored for different percussive sound types. The Ospray-8 contains 8 modules connected together, comprising of 4 X Drum Modules, 3 X Cymbal Modules and 1 X Handclap module. There is then a housekeeping module that handles midi control, and stereo outputs."
