For Bass & Guitar (or anything else you fancy plugging into it) This is spawned from the 'Woolly Mammoth' but takes it a LOT further. The mids pot transforms this from a limited scooped, bass heavy fuzz to a punchy, fuller fuzz. Used in conjunction with the 'mode' switch you can create a tight, more focused fuzz/distortion. The 'mode' toggle switch gives you two choices, a huge bottom heavy fuzz or a tight, sharp distortion ideal for chugging palm muting riffs. Maxing the gain and using your guitars volume knob to tame (if you desire) gives much more effective results.
