This is a mostly transparent boost. Use it before your distortion or fuzz to thicken it up, or later in your signal chain to push your amp into overdrive.
It has a soft-touch foot switch, with relay true bypass. You can hold down the footswitch to temporarily boost, or tap it to engage/bypass. Hold the foot switch while powering it up to toggle auto-on.
It features a shamrock-shaped hole with an acrylic window.
