Before we start, yes I have 'done a search' I need a distortion pedal for bass, I play everything from Metallica to Less Than Jake and I have found myself needing some distortion to sound right. I dont want a lot, just a minimal amount, like a growl, but growlier. Please bear in mind that I live in the UK and am on a limited budget. I think Ive narrowed it down to three: Boss ODB-3 Ibanez PD-7 EHX Big Muff (probs with the lows?) Any ideas?
