MXR Micro Amp ( M133 ) built on the Attribution-ShareAlike (CC BY-SA) Licensed PCB available from: https://www.pcbway.com/project/shareproject/MXR_MicroAmp.html. Bare white enclosure.

"The M-133 MicroAmp is a clean boost/volume pedal, part of the first Reference Series by MXR released between 1973 and 1984. The original stompbox did not have power-on LED or A/C connector.The main application of this pedal is to do louder solos. It can also supply a permanent boost in a long effects chain or cables where the signal drop is a problem. Placing it before the amp the signal boost will drive the preamp harder and into more saturation."
