TWA Scott Henderson SH9 (Green Font) Distortion Effects Pedal

Signature distortion pedal of American jazz guitarist, Scott Henderson.

The Scott Henderson SH9 from TWA is a signature distortion pedal inspired by the classic SD-9 circuit to deliver thick, compressed, amp-like tone. For the past 20 years, Jazz Fusion guitar great Scott Henderson has had a Maxon SD-9 Sonic Distortion parked on his pedalboard. Still, there were several shortcomings to the SD-9 that Scott and many other players had discovered. Chief among these were a loss of low-end on high notes and a Tone control that was basically unusable past the 9 o’clock setting. This Scott Henderson signature pedal provides improved bass and lower midrange response along with increased “girth” on high-register notes.
