Fantastic sounding high gain distortion box by Amptweaker. The Tight Rock is built like a tank, has some very cunning in/out features, an EQ option, noise gate and it can make any amp roar (even at low volumes). If you run a Fender style amp but crave that Marshall juice, try this robust lil pedal. Designed by amp tech legend James Brown, this one is in as new condition and comes with the box.
