HEADPHONE AMP COMPLETE KIT

A complete kit for a replica of the MXR™ Headphone Amp, a simple guitar headphone amplifier for quiet practice. You supply the enclosure.

About the effect

The MXR™ Headphone Amp is a simple headphone amplifier for guitar, similar in design to the MXR™ Microamp™. The GGG project version adds a footswitch that sends the output either to your amp (line) or to your headphones, so it can live in your effects chain, plus an optional effects loop on the input so a speaker simulator or EQ can shape only the headphone signal. The loop uses Switchcraft enclosed jacks because they are smaller and easier to fit. Thanks to Alfonso Hermida for the schematic information.
