Product Description
With the popularity of Amptweaker's smaller footprint JR series, Amptweaker added bass and guitar versions of their Fuzz pedals... introducing the Bass BluesFuzz JR. These pedals share most of the tone-tweaking features available on their larger counterparts, while eliminating effects loops, lit controls, battery switches and boost features that some players don't need in order to shrink down the size and weight. The Bass BluesFuzz Jr is based on the BluesFuzz Limited, a special 49-piece model Amptweaker built back in 2014 to commemorate their 5th anniversary.

Derived from Amptweaker's Pro series, the Tight control and Fat switches were re-configured into a 3-position Fat/Normal/Tight switch to dial in the attack of the notes from thick and heavy to aggressive and chunky. Since this model uses a low gain germanium transistor, an input boost is included to give thicker fuzz tones. And to help dial in the all important mid frequencies, there's a Mid control. Amptweaker's popular automatically adjusting bias on the Fuzz controls 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 bass pickups too.

Other features include true bypass switching, 9-18VDC operation, and a thumbscrew-removable bottom plate with special holes to even accommodate tie-wrap or screw-in pedalboard attachment methods. Power supply not included.
