Much more than a simple delay, the BitQuest from Canada's Dr. Scientist is really a compact multi-effect pedal, but one of its best features is its ability to produce genuinely unique, and genuinely filthy, delay tones. It features eight different effects, including flange, a couple of filters, reverb, pitch shifting, ring modulator, bit crushing, and delay. Each effect has a clean and dirty version, selectable via its Dirty/Clean toggle switch. This pedal's distortion potential is beastly, and when a dirty delay sound is selected, the distortion comes after the repeats. This can result in some high-gain, fuzzed-out echo the likes of which I have not heard in any other pedal. Even on the clean setting, the BitQuest can wreak havoc on repeats, with delay tones than range from pleasantly lush to glitchy, stuttering, and completely warped. Rarely has such a compact pedal yielded such incredible potential for the adventurous, dirty delay-obsessed guitarist.
