Roland MC-202 // Analog Vintage Synthesizer // BEAUTY!
Note: links to listings are affiliate links for which the site may be compensated.
via this Reverb listing
"This is the iconic Roland MC-202 from the golden era of analog synths... and this one is in beautiful condition!
The MC-202 was part of the Detroit, Belgium and Dutch house scene in the late 80s, early 90s. It's therefore becoming a rare unit nowadays, most units you find on the market were HEAVY used during those decades. Plus way less units were produced comparing to it's two fraternal twin the SH-101.
The MC-202 is basically a SH-101 with tons of additional sequencing features, CV in/out options, double sync etc... and a display! Its a gorgeous unit and it's sounds are all instant house music.
Important things to consider buying this beautiful unit from us:
No discolouration or faded teint of the outer shell like most units have!
Clean Battery compartment, most units had battery leaks in the past creating future problems on the boards, like also the case in many 606 and 303 units.
Display like new, most units have faded/watery displays.
No destructive devaluating mods have been done, no drilling in the case, etc."

Moog Source Analog Synthesizer SN 4339 w/ Extras

via this eBay listing, also on Reverb
"A true piece of synthesizer history, the Moog Source (early 1980s) was Moog’s first synthesizer to feature programmable patch memory—a groundbreaking step that combined classic analog warmth with futuristic digital control. Revered for its lush, fat Moog tone and its pioneering optical alpha dial interface, the Source is both a collector’s dream and a player’s powerhouse.
This unit includes its original factory presets on cassette, the original owner’s manual, preset sheets, and the original schematic—a complete package that rarely surfaces.
Key Features:
Monophonic analog synthesizer with dual oscillators per voice
37-key keyboard (C–C) with octave shift & pitch/mod wheels
Oscillators offer sawtooth, triangle, and square (with PWM) waveforms
Oscillator sync + noise generator for deep sound design potential
Classic 24dB Moog Ladder Filter with self-oscillation & keyboard tracking
LFO with multiple waveforms routable to VCO or filter
16 patch memory slots + cassette storage for presets
Innovative optical alpha dial with LED display—clean, modern interface design"

"My recreation of the Mica-Sonic Electric Bongos.
Here's Soundgas description of the Stromer Bongos:
'A handbuilt analogue recreation of the fabled electronic percussion circuit as used by Madlib and on the legendary recording of Ann Peebles 'I Can't Stand the Rain'.'
These are handbuilt in small batches so expect some inconsistencies with the finish - sonically they're very close to the originals (though all originals vary in tone/timbre now due to component ageing/drift."
Each drum tone has a trim pot inside that's been adjusted so that the oscillator is just below the point of self-oscillation. When triggered, the circuit oscillates at its resonant frequency and rings out like a drum. Pushing in the 'mute' button shortens the decay.
To play these you need something that sends trigger pulses, like a beat- or key-step pro, or a drum machine with trigger outputs. Works with your standard center negative 9 volt adapter (not included)."
