Overview
The Turnabout is a variation of the Andy Timmons pedal produced by JHS
®
, which is in turn pretty
much a clone of the MI Audio Crunchbox. It produces thick, meaty distortion to emulate cranked 4x12
type tones. The Turnabout offers two additions: an asymmetrical clipping option and a thickness
control to dial in the low end.
Controls
• VOL:
Total output.
• GAIN:
From medium to high gain distortion. The gain control is interactive with the Thicc control.
• TONE:
Low pass filter.
• PRES:
The Presence control is interactive with the Tone control. Higher values increase the
overall presence which in turn pushes the tone control into a brighter range.
• THICC:
Controls the amount of low end sent to the clipping stage.
• COMP:
LED, Schottky and asymmetrical clipping. LED is the loudest (stock to the CrunchBox),
Schottky is the most compressed and the asymmetrical mosfet clipping is in-between.
