A transparent overdrive in the Centaur style, so it adds gain without colouring your guitar and amp. The Gain knob is a dual-ganged pot that blends clean and clipped signal, taking it from clean boost through edge-of-breakup grit to full overdrive; Treble gives 12 dB either way at 3 kHz and Output sets level. Germanium diodes handle the soft clipping and an internal voltage step-up keeps headroom high. Buffered bypass, 9 V battery or centre-negative supply. 120 x 104 x 65 mm, 490 g.
