Tritonaudio BigAmp is a small, high-quality Intsrumenten preamplifier for use in the studio or on stage. Not much larger than an XLR connector, any instruments such as bass, guitar or synthesizer are simply connected via a 6.5 mm jack input and their signal is not only amplified, but also directly balanced. This results in a significantly better sound quality and reduces humming.
