Seeking recommendations for a sub octave pedal to do basically one thing well: Make dramatic, bowel-shakingly low drone notes on recordings. That’s it, really. Not planning to do any rhythmic lines, keyboardish parts, or high octave FX. Not planning to use it thicken riffs. Just drop a low F-shart here and there. Desired features: It can handle dealing with a low B Doesn’t sound weird, delayed or out of tune on initial attack Makes tones so fat and deep that the listener must roll a dc 12 Con save or crap their pants Nice to haves: Not gigantic fax machine footprint Not too synthy Thanks!
