Re: Quick JB question
The JB will probably be too mild for Kreator. It's tighter than the ToneZone, but that's not saying a lot! It does get muddy sometimes.
Try the Duncan Distortion, as suggested by Travis. It's a tighter, meatier JB that should satisfy your Tormenting, Corpse-Ripping needs :fingersx: :laugh2: . Also, you could try the Dimarzio Steve's Special. It's VERY tight sounding, though it doesn't have the PAF tone.
Have you tried lowering the TZ's height? Try it as low as it will go, then work your way up. I've seen a few TZ users slanting it a bit, with the lower string side a bit further from the strings. Try backing off the gain a bit... as obvious as this may sound.
Good luck, man!
