I'm finding it very hard to find a thick/warm/dark sputtery fuzz to be run in front of a clean 6L6 amp....most sound very ice picky & sterile. I have a Hartman SFZ dual stage fuzz that sounded amazing with my Marshall JCM 2000 (set clean) but now sounds thin and harsh with my fender dual showman reverb + orange 4x12 cab (with v30's). I tried running it with an OD pedal both in front & behind but find I only get opposite ends of the spectrum...very high and harsh or very low and muffled. I'd probably be looking at a silicon fuzz with a bias control to attain some sputter. Any suggestions? P.S I use a Strat & LP and play post-rock/shoegaze/indie rock Thanks in advance!
