just get the sonic stomp, cheap, small, you won't know till you hear it, it's great! esp for tightening up bass if you're a metal player/chugger. The best analogy I can think of it's like upgrading from a seymour duncan to a BKP, more clarity and sparkle for clean and distortion. If you don't use it right you will end up scooping your tone, unless you want that. Dials at 12 o'clock work fine and are a starting point. I sometimes notch up the bass to 1-2 o'clock. It's an 'always on' type of pedal. Works best for me in my serial loop of my engl or marshall.
