This is a bass booster from ALBIT. It's positioned as a fuzz-like, amp-like distortion effect. It's an effect pedal that really brings out the delicious low-mid range of the bass, and I think it's a very practical pedal. They're becoming less common recently. How about getting one before the price goes up? No box. Thank you. - Brand: ALBIT - Model: GW-1B - Type: Germanium Diode Booster - Application: For Bass - Controls: Gain, Master, Tone - Features: Bypass function Thank you for looking.
