Yamaha Electone E75 rare synth (voice cards of CS-80 and GX-1)

Electone E 75 Bass and string sounds

"Some bass and string sounds from the Yamaha Electone E 75. If you recognize some melody from GroBschnitt Solar Music you might be right.....
My iPhone does not manage the bass sounds correctly... The sound comes from the E 75, TM5 cabinet and also through a keyboardamplifier with an EHX Small Stone pedal."

"This synth looks like an organ but in fact shares most of the voice cards of the Yamaha GX-1 and CS-80, which currently go for ($300,000+ and $25,000+ respectively). I have to sell this due to moving.

The Yamaha E70 is the more well known model, but the E75 adds the well-known string sounds from the CS-80. This is the only one E75 I've ever seen for sale in Australia.

The other amazing thing about this synth is the presets on all voice cards are controlled by simple resistors. To make each voice fully programmable just replace resistors with potentiometers. Here's the guide to do it.

The synth works perfectly except there is a stuck note on the foot pedals (deep bass). This can be turned off and it still played (including with bass). The stuck note is a common problem and will be a damaged diode or resistor on the bass foot pedal CV controller.

Cosmetically it's in excellent condition, with 3 blemishes shown in the pics which should be straight-forward to fix. The listing includes the foot pedals, they're just not attached at the moment (they're in the last pic)..."
