Headphone Amps

Headphone amps let players monitor a guitar or pedalboard without a conventional speaker cabinet. They may provide a clean headphone output, an amp voice, cabinet simulation, an auxiliary input, USB recording or a direct feed to an interface or PA. Output impedance, volume range, stereo behaviour and the presence of a cab filter all affect the result. They are useful for quiet practice and travel, but check the intended signal path and do not assume every headphone output can drive a passive speaker.
