MXR™ Headphone Amp

A very nice simple headphones amp for your guitar. Similar to the Microamp. Thanks to Alfonso Hermida for the schematic information.

We built on with a configuration such that it can go in a effects chain with the footswitch switching the output sound from the line to your amp to headphones. We also built an effects loop on the input so that a speaker simulator or EQ could be included to effect only the headphone sound.  Switchcraft enclosed jacks were used for the loop since they are smaller and easier to fit in.
