This a vintage 1970's Bob Moog design that really does sound incredible. My favourite thing is that the rate ramps up and slows down like a Leslie speaker. Unique combo effect.
It is BIG! Designed so that you can control it with your feet - so unless your pedalboard is huge I'd recommend having this as a studio piece, which it has been since I've owned it. It regularly gets attention as it really stands out from other pedals.
Good working order, comes with power cable. No trade thx.
