I'm looking for a boost to push my Blackstar a little harder.

I specifically dont want a TS style boost though, that midrangey/bass cut sound that "tightens things up" for metal and such.

If anything, I want a LOOSER sound, lots more gain and looser bass, think, Josh Holme of Queens of the stone age. That kind of low middy grind.

Any ideas? was looking at way huge but theyve got like 4 different overdrives and I dont know the difference.
