The 400 with Flangulator

"The 400 with Flangulator was a commission from a very generous guy in Phoenix, who in-turn gave it to Nick Rhodes (currently behind a velvet rope in his London studio). I re-worked an old EH-400 Mini Synth brain into a new case, added real keys from a smashed Farfisa Compact and incorporated a hybrid flanger/ring modulator circuit. Also features a pseudo-ribbon controller for the stop frequency and a way cool "magic lamp."
The Custom 500.

"The Custom 500 is about as complicated as I want to do. Features a looping delay, dual stage distortion, vocoder, oscillator and roto-phone-vibe. This was a commission for Stephan in California (thanks for the tour!). "
The HL-1958

"The HL-1958 Synth is a 20 key synth with envelope filter, 1 second looping delay (that also does flange, double, echo, etc.) and a dual-voice brain. Contols for sustain and pitch warp. And of course a classic analog meter to go with the classic analog sound. Now out in Los Angeles..."
