images via this auction

"The item listed here is the bass version. This is a very cool and rare tool for the synth players and collectors out there. The Slavedriver was a guitar to control voltage converter for a synthesizer. You take the 360 System Slavedriver and connect it between your synthesizer and guitar and you are able to manipulate your guitar with the sounds produced on your synthesizer. It allows the guitar player to control any keyboard with CV input through your guitar.

The 360 Systems Slavedriver was one of the first units that allowed a guitar player access to the synthesizer world and all the insane sounds they make. The model we have for sale is a bass guitar version of the guitar interface and is meant to work with any 4 string bass guitar. It features a variable octave selector switch as well as several synthesizer and footswitch outputs. The Slavedriver for sale comes complete with the 4 piece magnet bass pickup which is needed to control the synthesizer sounds."

"Loosely based on the Atari Punk Console with some custom tweaks and an LFO front end, this box makes a ridiculous amount of different sounds, all from three 555s. This is a kit version complete with knobs and case. It's open source (see the instructions and surrounding pages) and has small area on the pcb for easy circuit bending. Created by recompas.com. Complete assembly instructions are available. We also sell a completely assembled and tested version."

EMS SYNTHI HIFLI GUITAR SYNTHESIZER EFFECTS PROCESSOR

images via this auction

"The Hi Fli (aka The Sound Freak) was designed by David Cockerell in 1971 for EMS. He later went on to design many of the classic Electro Harmonix effects (both the Micro Synth and Small Stone phaser are inspired by the Hi Fli). Only 350 were made making it a collector’s gem. David bought a prototype in 1972 and from what he recalls it was “very, very expensive”.

The Hi Fli was actually referred to as a synthesizer in the original ad, but it’s basically an analog multi effect processor, which can be used on vocals, guitars and organs. It has two footpedals, which could be routed as control voltages/expression pedal to any of the slider functions. It’s got no memory to bank up settings, - everything is in real time, so one had to manually tweak the sliders for each tone change.

Features; top boost (30dB treble booster), octave shifter (1 drop), buzz (treble booster to octave effect), ring modulator, sustain fuzz, solo/strum sensitivity control, bypass, modulation selector (rotary, phaser, vibrato and different types of auto-wah).

David is seen using the Hi Fli at Earl’s Court in May 1973. It was also used on the Dark Side of the Moon recording sessions. It’s not reported which songs he used it on, but it might have been for creating auto wah effects on Any Colour You Like and fuzz on live versions of Time.

The Hi Fli is still in David’s possession and last seen at the Interstellar Exhibition in Paris in 2004."

EDP SPECIAL WASP

Note there is more going up on MATRIXSYNTH-B as well.

"Later versions of the Wasp included the Wasp Special (released 1981) which came with wood panels, a black and gold color scheme, and an internal power supply but no built-in speaker. And then there was the Wasp Deluxe (released 1979) which had all the features of the original plus a standard 3-octave keyboard, wood panels, an oscillator mixer, external audio-in, a larger speaker, and battery operation. EDP also produced a heavily modded Wasp that was built into a guitar form called the Keytar. It had a two octave keyboard and transpose and portamento buttons on the neck, only two were ever made as far as we know."
