Herb Deutsch's Moog SOB (by Synthpro)


"Hey Guys,

Here is a little different video for all of you going over Herb's Moog SOB (better known as the Opus 3) and the history of this particular instrument released by moog back in the 80s.

Herb was involved in the design of the Opus 3 and I am very honored to have the opportunity to work on his actual instrument.

(Note: when showing the Chorus schematics I did forget to address that the 2 LFOs are modulating at 20Hz and a 2Hz signal...this is also how you get slow/fast rate based off which LFO is selected. These LFOs are actually modulating the clocking oscillator running at roughly 300kHz to clock the SAD512s....this is that circuit behind where I talk about the sine wave conversion)

Thanks again Herb and to all of you who watch my videos.

"This is the second/final part of the series on Herb's SOB (Opus 3).

This this video, I go over more in depth of the chorus after repairs and a good overview of the features of this instrument to show its 100% working.

Thanks again Herb and to all of you who watch, I greatly appreciate the support.
