It's a chip amp! I do love this line: Battery Charge and Sound
An interesting feature of the BYOB amplifier is that the sound character is related to the battery charge. With a fully charged battery the sound is tight with explosive dynamics (can't get that with any other amp), while with a low battery charge the sound character resembles that of a no-feedback amplifier, very laid back and relaxed.
So changes of tone doesn't mess with the sound? I thought that amps weren't supposed to change the sound. That IS distortion in my book. LOL
