from bass player magazine "Smallsound/bigsound's flagship bass fuzz has been updated for an even wider range of overdrive and fuzz tones with clean blend. The enhanced controls include the ability to blend overdrive and fuzz, phase inversion, and even more gain. The true bypass stompbox only uses an AC adapter, because the company doesn't want players using batteries and harming the environment."
I don't use batteries since I brought back my first pedal I ever bought, cause I thought it was broken down.. Wel I was 13 or something like that so no shame now But since then no batteries.. Cause changing all my pedals batteries by now would cost me the same ammount of money a power supply I use to power all my pedals..
