Circuit-Bent Roland TR-505 drum machine

via this auction

"Diabolical Modified Circuit-Bent Roland TR-505:
The Diabolical Roland TR-505 Mods are very similar to the TR-707/727 Modifications which make use of added independent Clock Sources to control the pitch of individual sounds. On the 505 we add 6 pitch controls which affect Bass, Snare, Congas, Toms/Timbale, Cowbells, Hand Clap/Rim. Each Pitch control has a bypass switch that selects either the adjustable clock oscillator or the original 707 CLK. We have also added a 10 point circuit/ROM bending patch bay made from high quality banana jacks (patch cables are included). Linking patch locations will generate a wide variety of modulate, filtered, bit reduced, and otherwise unique effects. The combination of pitch controls and circuit-bending can create some truly one of a kind sounds.

Diabolical Devices aka Class A Electronics, LLC is a leader in Professionally Modified Synthesizer and Audio Equipment, Expert Repair Services, and has a full line of Hand-Wired Tubes Amplifiers and Effects (Diabolical Amplification). Their work has been featured at NAMM, art galleries, music videos, countless tech blogs, and used by musicians all over the world, professionals and enthusiasts alike. The circuit-bending and synth mods are the work of head-technician James Gramling who has spent the last 12 years in professional audio service and electronics prototyping. Check out the new www.circuit-bent.com for updated specs, custom work questions, and new releases from Diabolical Devices."

Admin: Ebay RSS Feed Update

I fixed the Class A Electronics feed and added Gear Orphanage in the MORE STUFF section on the right. If any of the feeds seem odd, just unsub and resub. I just subbed to all, one by one. It was a little painful but it is done and now I can forget about checking the links manually - all listings will come into my RSS reader. Note not all auctions get a post on the main site or even MATRIXSYNTH-B. Only those specifically sent in and/or those with the best pics, rare items, or interesting bits go up. Each post is meant to illicit a response. Each post is meant to stand on it's own, in the archives, when the auction is long gone.

ARP Little Brother Vintage Analog Synth CV Oscillator

via this auction

"Oh, no we didn't!

An ARP Little Brother is loose!

This spunky little devil works well and sounds great! The housing is in good shape overall showing some moderate scratching. There is a little bit of white paint speckle at the top of the control area. All controls manipulate the synth as intended. The controls for the "Brass" and "Alto" switches are a little stiff but not damaged. Jacks, faders, and switches are intact and should hold up for a while still.

This guy is great! Perfect sidecar oscillator for any CV/Gate analog synth. No envelopes or filters to get in the way of your madness. Use it as a stand-alone synth and play it by the pitch bend control for theremin sounds! Get busy!"

Folktek The Bug 10

via this auction
"The Bug 10 By Ben Houston .
This custom piece is part of a folktek series entitled "philanthropoid"". Known simply as the Bug series. Also in the series on the site and around the world is the Mantis, dronescape sequencer,the book of sound, the moth, the growling insect, the bug, the octa-hedra, walking stick, pendulum translator and others. The sound is phenomenol and continues to amaze us. It is a sonic symphony of nasty and grimy sweetness, endless layers of sound possibilities emenating from High quality OSC originally based on high tech speech synthesis. Seemingly random bits can be rediscovered time and time again and then there are those moments that you will most likely never rediscover. Endlessly captivating, this piece WILL provide sounds that you will not find in other synthesizers and will astonish you every time you turn it on.

This particular piece features four patchable knobs, and a twelve point magnetic patchbay. This allows you to determine function and provides tons of flexibility. In addition, two more knobs (global knob control and power kill) , glowing lamp power indicator , 2 folktek button/switches for activate and freeze mode sections, reset, 1/4" output, basic manual of function and layout. You'll be able to cipher through waveforms and textures with extreme sensitivity in thousands of ways. Waveforms (individual, or multiple layers) can be captured and maintained, often intermodulating in beautiful and/or disturbing ways. Super sensitive knobs let you filter through tons of sounds and glitchscapes. Albums are waiting to be created here as the sound is quite different from anything else you'll find.. Includes DC adaptor"
