Analogue Solutions TBX-303

Note: Auction links are affiliate links for which the site may be compensated.

"Designed to emulate the sound of the TB-303, this synth does that and more! This is the original model that includes features not on the second version, namely an overdrive and an LFO. This particular unit is in great condition. There is some scratching on the unit (as seen in the photos). All of the knobs, switches, inputs, and outputs work exactly as they should. One thing that should be noted is that there is a slight design flaw that was remedied on the second version: When controlling this synth via MIDI, the lower octaves just make fun out of tune flubby noises. It isn't until you reach the higher octaves that it starts to sound like a synth. It's not a fault with the unit, just the way it was designed. It still works a-okay...

key features of the tbx-303:
pure analogue voice circuitry.
accurate tb303 circuitry clone.
physically the same size and layout.
extra tone controls and circuits for more sound variety e.g. lfo, crossmod.
rugged steel construction.
midi in for software sequencer control."

via this auction

"Up for auction today is an Analogue Solutions Telemark. This is a great sounding synth that bases its architecture on the original SEM but with more patch points. Being semi-modular in nature, it doesn't get much more versatile than this. This particular unit is in immaculate condition. Aside from scratches around the screw holes, it is in perfect cosmetic condition. All of the knobs, switches, inputs, and outputs work exactly as they should...

Key Telemark Features
Semi Modular Analogue monosynth
Pure analogue voice & modulation circuitry
Sub-Oscillator / Divider – for more beef
Ring Modulation
Patch points to allow more sound types, and to cross-patch with your modular synth’s
SEM type sound
Similar SEM layout
More features than the original SEM such as Sample and Hold, LFO Square wave, Noise, extra inputs, many more signal modulation options via rotary switches
Plenty of modulation possibilities
Rugged steel construction
MIDI In for software sequencer / keyboard control

Rare Early Moog Prodigy Synthesizer SN 1702 with CV Mods

Note: Auction links are affiliate links for which the site may be compensated.

via this auction

"This Prodigy has never been gigged and is in near mint condition!

It has a very low serial number of 1702 and includes a bit of history-its mod work was done by the trusted and iconic Lipham Music Co in Gainsville FL where a young Tom Petty worked in the late 1960s after taking lessons there from Don Felder, one of the original Eagles.
Lipham regulars included The Allman Brothers, Blackfoot, Iron Butterfly, Tony Joe White and The Royal Guardsmen and Bo Diddley.

It recently had $400 worth of work done by Music Technology in Springfield VA including replacement of caps, LED, regulator, resistors, set volts per octave and tuned oscillators and has not been used since. The original mod cables are included in the price. They are clearly marked and there is a schematic diagram on the back of the synth.
There is a tiny chip in one of the keys (see photo) other wise it is in beautiful original condition.

The Prodigy is an incredible machine with a totally gorgeous classic Moog sound and very heavy bass capabilities. The filter on it is the most organic of all the vintage Moogs, and is the go to for a vintage Moog short of a Model D. With two oscillators and *THE* Moog filter, this little synth stands tall among the rest of the classics."

Oberheim OB-X SN 793401 with Kenton MIDI

Interesting note about the the earlier 'block font' logo.

"The Oberheim OB-X was intended to be a more convenient version of the Oberheim Four Voice, with voice cards that are very similar to the SEM module. Unlike the Four Voice, the OB-X had a unified interface for changing parameters and proper patch storage (thirty two patches in four banks of eight). Unlike the later OB-Xa and OB-8, the voice circuits in the OB-X are all discrete components, giving it a sound much more like the SEM based synthesisers (it also makes it easier to repair as there are no hard to obtain chips).

This is one of the first ones made, with a serial number from 1979 and the earlier 'block font' logo rather than the later 'cursive' one. The serial number label also shows it was built as, and still is, a four voice model. I bought this synth in 2010 from Tonetweakers in the USA, who fully restored it before shipping it to the UK. I then took it to Kenton Electronics, who fitted a MIDI retrofit that allows the synth to both transmit and receive MIDI. As part of the restoration, the keyboard bushings were replaced so the keys are level (I've included a shot looking straight on at the keyboard to show this).

The synth has spent the last five years in my little home studio and has never been gigged, and it can be heard on a number of tracks on my Soundcloud page. This is the same kind of synth used by the likes of Japan and Killing Joke - it provides the amazing sounds on Killing Joke's 'Night Time' album, including the legendary track 'Love Like Blood'. I really don't want to part with this synth, but I need to pay for work on my money pit of a car!.."

Coco the Cat Covers Good Vibrations with a Mini Theremin

Coco Mini-Theremin Demo Published on Dec 25, 2014 mdaane1

Good Vibrations - Theremin intro

Synth trivia: the theremin sound on Good Vibrations was actually the Tannerin.

"The Electro-Theremin was a unique electronic musical instrument developed by trombonist Paul Tanner and amateur inventor Bob Whitsell in the late 1950s to produce a sound to mimic that of the theremin.[1][2] The Tannerin was a later re-creation of the original. The instrument features a tone and portamento similar to that of the theremin (or thereminvox), but with a different control mechanism. It consisted of a sine wave generator with a knob that controlled the pitch, placed inside a wooden box. The pitch knob was attached to a slider on the outside of the box with some string. The player would move the slider, thus turning the knob to the desired frequency, with the help of markings drawn on the box.

The instrument was custom-built at Tanner's request. Tanner appreciated the theremin's sound, but wanted greater control of pitch and attack. The Electro-Theremin uses mechanical controls, a long slide bar for the pitch (analogous to the slide of the trombone that was Tanner's main instrument) and a knob to adjust volume. This contrasts with the hand movements in space that formed the original theremin's signal feature. The Electro-Theremin also produces a slightly less complex timbre than the original. This is not due to the nature of the instrument, but due to Dr. Theremin's intentional harmonic generation in the output of the Theremin, which Tanner did not do."
