BAXSTABBER is a EQ/preamp/tone shaper and possible level boost that takes any signal you feed it and applies the famous Baxandall EQ (simple treble and bass control with variable mid control based on where you set the T & B) with 144 different tone stacks of his/her choice via the two (2) 12-position rotary potentiometers (the pointy yellow and green knobs).
This pedal can be placed in any position on your pedalboard. Place it first and have a switchable tone stack to drive your other pedals. It will alter the sound of your instrument and pickups. For example, set up a tone stack/sound to change what EQ/sound you feed your other pedals. Place it after your all of your pedals and let them be affected by the tone stack.
