The Bass BluesFuzz Jr fuzz uses a low gain germanium transistor, and has mid EQ, and a Dry Low blend. The Bass BluesFuzz JR shares most of the tone-tweaking features available on their larger counterparts, while some features many players don't need in order to shrink down the size and weight. The popular automatically adjusting bias on the Fuzz controls bias keeps the sweet spot at hand, and is especially nice for cleaner tones. And the Bass BluesFuzz JR has a Dry Low control on the side, to help dial in the bottom even when setting the fuzz for tighter tones. All Amptweaker fuzz pedals have a built-in 'guitar-style impedance, which allows you to put any other pedals in front without the traditional issues associated with vintage fuzz pedals. That means it works fine with low impedance active basses and pickups too.
