About

GBAmp is a little but powerful amplifier module made to fit your favourite Game Boy.
Most Game Boys has pretty low spekaer volume, but GBAmp can make it sound so that your neighbours can hear it :) GBAmp is a "Hi-Fi" grade cutting edge industrial Class-K amplifier with AGC which is more power efficient than Game Boy internal amplifier. This can help your batteries last longer.
