JHS Overdrive Preamp Pedal Features:

• Overdrive stompbox based on a '70s-era prototype of a well-loved classic
• Boasts a simple 2-knob control layout
• Gain knob dials in everything from subtle grit to all-out grind
• Level varies between a subtle "always on" sweetening effect and an arena-worthy solo boost
• Slider switch alters the pedal's clipping arrangement, unlocking a whole alternate set of tones
• Use it to front load a British-voiced high-gain amps for instant Yngwie-esque textures
• Sounds like a vintage gray 250-style stomp with more gain and different low-mid voicing
