A side-mounted six-position SWEEP rotary switch selects frequency ranges without changing the rest of the rig. Internal Q and input-gain trimmers default near 12 o’clock and shape peak intensity and drive into the circuit. Internal DIP switches switch between guitar and bass modes, with bass mode extending the sweep for lower-register instruments.
The mk.2 keeps true bypass and adjustable rocker tension via the included 4 mm Allen key. A custom rubber tread replaces the earlier plexiglass footplate. Released in 2026 as the successor to the Wahcko line that has been in production since 2008.
