"Very interesting TR-909 clone, apparently made from a French kit. Actually, this actual machine looks absolutely identical to the one featured on Crazy Patroche's website - so the one he made, rather than one made by others from the kit? Unfortunately it needs some work. Here's our tech James' report:.

Random hum cuts in and out. Snare sound faulty, no body and snappiness. One of the tuning pots perhaps wired backwards, clockwise tunes down. Still a great and presumably fairly simple project. Packing to include UK or Euro lead: 9GBP."

"Analogue Solutions Colossus AS200 Slim, bought direct from Analogue Solutions in 2022. Light use only in a smoke and pet free home studio.

Mint condition apart from one small dent in wooden top piece.

Can be mounted on top of Colossus Classic AS100 to make a double-stack Colossus. (though that might possibly be greedy)

Website and tech specs here: https://www.colossus-synth.com/colossus-2

I upgraded many of the original knobs to EMS style Cliff knobs myself. This will not be in second chance sunday. It comes with a full set of matrix pins, a selection of patch cables that were included with it, and the original set of AS knobs.

VEMIA can collect and pack (90GBP) for onward delivery /shipping."

"An excellent condition vintage Arp 2600 semi-modular which contains the sought after (and so-called) pre-lawsuit Moog 4012 style filter. This instrument is at least 50 years old (built between 1972 to 1974) looks beautifully vintage and sounds absolutely amazing.
A full service was carried out by Kent Spong at KSR in July 2024.

Some of the casing has been re-tolexed very well. Both lids are included, and everything is in very good cosmetic condition."

TherapSID mk 3 Synth Module SN TS322010

"The TherapSID mk III is the final and best version of an awesome synth module built around the Commodore 64 SID chip. This one features an original 6581 SID chip pulled from a broken C64 (although the module can also host new SID emulator chips).

To quote the manufacturer: 'Named after a vicious dinosaur, its sound is no less aggressive. TherapSID has evolved to create roaring noises that will cut through your mix like razor-sharp claws through a mammoth steak.'

TherapSID unlocks the power of the SID's 3 oscillators plus noise and multimode LP/BP/BR/HP filter and adds 3 envelopes, 3 LFOs, a fantastic arpeggiator, 3 CV inputs, and much more! It can run up to two SID chips at once, with audio inputs and outputs for each chip. This unit is running firmware version 2.6, but other versions can be installed over MIDI."
