The #1 Echo is part of the Electro-Harmonix line of Micro (xo) guitar effect pedals, with a small die-cast housing. But don't let the size deceive you - it produces some of the finest digital echo available, with a full two seconds(!) of maximum delay time. Echo/delay effect is controlled by feedback and delay time knobs. A blend control lets you adjust the amount of delay in your signal to make sure the Micro #1 sits exactly where you want it in any track or performance.

A rugged footswitch selects whether the #1 Echo pedal is engaged or bypassed, indicated by an LED. When in Bypass mode, the output jack is connected to the input jack through a buffer. It's equipped with standard 1/4" instrument I/O jacks. The barrel connector is for a 9-volt battery eliminator capable of delivering 100 mA of current. The inner ring of the 9-volt battery eliminator must be negative, the outer ring positive. The unit's battery may be left in or taken out when the eliminator is in use.
