This was an improv made this using two rows of the modular’s Q119 sequencer to control/trigger both voices on the Yamaha CS-40m, and also toggle the Space Echo’s sound-on-sound feature using an analog switch. Seaborne
Horizon

I recorded this right after acquiring a 1973 Gibson Triumph (Les Paul Recording bass) from the original owner who had it in storage since around ’75! The original flatwounds were even still on it. =) They were sooo dead, but had this nice “plonk” sound to them – and so began this track… The melody [...]

Equinox

This track was made using a Fender Strat w/Roland GR-1 for the melody, Gibson EB-0 bass w/string mute, and my Oberheim OB-8 for the synth part at the outro. Equinox

Passage to Infinity

I made this track using a Multimoog for the melody and solo, and the bass is my 1966 Gibson EB-2D semi-acoustic running through an Alembic F-2B preamp. The funky “bar bridge” and resulting wonky intonation in the upper register gives that bass an almost upright-like character at times. The melody is being doubled in places [...]

Oberheim Four Voice (FVS-1) Restoration – Part 4: Hearing Voices

Now onto the fun stuff… I’ve been seriously digging this thing even as it limps along with two-voice polyphony, but its time to hear a happy quartet of SEMs! SEMs 3 and 4 were not firing from the keyboard, and the continuous assignment mode would only step between SEMs 1 and 2. Between all of [...]

Oberheim Four Voice (FVS-1) Restoration – Part 3: The PSU

Before venturing too far down the path of sorting through the faults, I wanted to first ensure that the power supply was in good working order – that the power output was clean, and that the rails were putting out the correct voltage. There are a total of six capacitors on the PSU board [...]

Oberheim Four Voice (FVS-1) Restoration – Part 2: Modification Removal

Well, where to begin… I thought I’d start by tracing out and removing the modifications. Overall, the mods looked to be in a questionable state, and I felt it would help in troubleshooting the primary issues if I could rule-out the modifications as a contributing factor. The “Mediamix Triangle Mod” board was held in place [...]

Oberheim Four Voice (FVS-1) Restoration – Part 1: Introduction

I’ve been fascinated by this synth most of my life, and I finally got a chance to lay hands on this one in June 2011. In or around 1975, Oberheim released the four voice polyphonic synthesizer (dubbed the FVS-1), which was basically comprised of four Synthesizer Expander Modules (SEMs; keyboardless, monophonic synths that were originally [...]

Refinishing a Thunderbird Bass

I’ve been dabbling with guitar/bass repair for years out of necessity and I’ve always wanted to try my hand at refinishing a bass, but I’ve never had the right candidate to practice on… until now. A Czech-made clone of a 1965.5 to 69 Gibson Thunderbird bass (referred to as the “non-reverse” body style) came into [...]

Fun with Breadboards!

I snagged an old Heathkit “Electronic Design Experimenter” off Ebay for around US $23, when all was said and done. Didn’t think I’d be excited about a breadboard – but this thing’s neat! In addition to the breadboard, it contains a bi-polar power supply (each rail independently variable up to 15V), pads to distribute 15 [...]
