Bass Pedals

Beginning with the Bass TightDrive, Amptweaker offered bass versions of many of our pedals when consumers asked for them.  In each case the tone controls are tuned an octave lower than their guitar versions, and the Tight control range is also set an octave lower.  On most of the models we included a Dry Low blend knob that adds in dry lowend so you can set the distortion tight and not lose bottom.
