The Dwarfcraft Zhago offers three helpings of sound in one tiny box. Blast your amp or other pedals with a powerful boost in volume. Crank up the gain, and hear your sound degrade into a splattered growling fuzz, then flip a toggle for a tight, gritty distortion with a strong gate. All powered from the industry-standard 9v center negative DC adaptor. True bypass (as usual) and assembled by hand.
