Electro Harmonix Hare-Lip

The Hare-Lip Microphone Echo is not a delay pedal. There are only four transistors on the circuit board. You tell me how to make stomp box delay with four transistors (we're not going to count phase shift as "delay," by the way) and I'll eat my hat.

The Hare-Lip is an interesting tremolo pedal. Dry signal mix is controlled by the VOLUME control. Tremolo signal mix is controlled by the ECHO control. Note that I am not saying tremolo depth is controlled by the ECHO because it is not. The depth is fixed. You can simply blend in the dry or the effected signal paths. This is unusual amongst tremolo pedals. SPEED, as you would expect, controls the LFO rate. I did not trace this, and haven't seen the schematic, but the tremolo quality is very on/off, so I would expect that either the LFO is a square wave or the attenuation device is a BJT which doesn't have much linear action between saturated and cutoff.

This particular unit was brought to me at least twice to verify that it was working (same unit). The casual user will assume that this is a delay pedal and think it is broken when there is no echo effect. It does say "echo" right on the panel! Adding to the confusion is the dry mix labelled "VOLUME" and tremolo signal labelled "ECHO" and you have a very odd pedal indeed.

The EH number for this pedal is EH 3004 which is one more than the original Big Muff Pi (3003). They have the same enclosure and knobs, so some crooked fellow could scrape off the HARE-LIP, ECHO, and SPEED graphics (leave the VOLUME) and try to pass this off as a broken triangle Big Muff. Buyer beware when shopping for triangle Big Muffs!
