I remember seeing a picture of an effect pedal that had a guy and his two eyes were red leds that turned on when the pedal was active. Does anyone know what the pedal is called? I think is was a fuzz/overdrive or a noise box type thing.
There is an overdrive literally called "Red Eyes" by Heavy Electronics. That may be what you had seen. http://www.heavyelectronics.com/RE/RE.html
Just going from youtube demos but to me the IdiotBox Mad Doctor and also the "chop" mode on the Diamond tremolo sound clearly different than a square wave tremolo. Both of these completely remove the signal from the audio path during the off cycle, to my ears the sound is more dramatic than a square wave trem.
Glad I could help! Right. I would say the Mad Doctor is more akin to a killswitch on your guitar than a square wave tremolo. I have a EQD Hummingird, and its more of a pulse than completely cutting out the signal. Its close, but not quite a complete kill of signal. Not to mention the Mad Doctor (from what I've read, never had the opportunity to try one out) has a knob that controls the ratio of on/off, where as a square wave tremolo goes at a constant rate. I'm not familiar with the Diamond Tremolo. I'll have to check that out.
