Amptweaker Bass Tight Fuzz Pedal


After introducing the immensely popular TightFuzz it was only a matter of time till bass players the world over got thiers. The Bass TightFuzz has all the same vintage tones as its guitar cousin, re-tweaked for bass guitar by moving the Tight, Edge and Tone down an octave, and also includes Amptweaker’s popular Dry Low knob which lets you blend dry low end with the Fuzz.

Customise your tone

The Bass TightFuzz includes a Tone control to tame the fuzzy edges and the Tight control, a mainstay of Amptweaker pedals, which varies the pick attack from smooth and thick to tight and aggressive.  You can get all kinds of great fuzz tones from this pedal.

Germanium/Silicon switch

This control changes the output stage from a softer, lower gain Germanium to a heavier, high gain Silicon transistor.  This pedal has the ability to get lower gain tones easily, with an Auto Bias that adjusts appropriately with the Fuzz control, to get the cleanest and nastiest distortions possible with one control.  It also has an Edge switch with a Smooth setting to further knock the edge off, and a 60's/70's switch that transforms the pedal from tighter, lower gain 60's tones to fatter and heavier 70's tones.
