Introduced in 2023, the Acorn Amp Migfet 50p is the company’s take on the Sovtek MIG50 guitar tube amplifier in a compact pedal format. After popular demand, this V2 adds more gain to the circuit by swapping 12AX7 preamp tubes (found in the original amp circuit) with JFETs.

JFETs can perfectly recreate tube amp-like compression and sag while delivering higher gain, without disappointing at lower settings, whether in clean or edge-of-breakup territory. The circuit’s EQ, dynamic and musical, is also voiced after the MIG circuit.
