THE μ-AMP

A small preamp with a long history.

Originally identified as ROBOT 1981, the μ-Amp is a compact onboard guitar preamplifier built around the NE5534. The present board keeps the original circuit concept in a clean, installer-friendly PCB format.

The board is supplied preassembled. The guitar pickup, control potentiometer, bypass switch, output jack and 9 V battery are connected off-board.
