MXR™ HEADPHONE AMP REPLICA RTS PCB

The ready-to-solder (RTS) PCB for our MXR™ Headphone Amp replica, a simple guitar headphone amplifier for quiet practice that can live right in your effects chain.

About the effect

The MXR™ Headphone Amp is a simple guitar headphone amp, similar in design to the Microamp™. The schematic information for this project came from Alfonso Hermida. Our build adds a footswitch that sends the output either to your amp or to your headphones, so it can stay in your pedal chain.

There is also an optional effects loop on the input, so you can add a speaker simulator or EQ that affects only the headphone signal. We used Switchcraft enclosed jacks for the loop because they are smaller. Separate schematics and layouts are provided for the loop and bypass version.
