+1 hard to go wrong w/ a SVT or V4,B,BH & a P-bass!!!! I use this combo reg. & almost ALWAYS leave all EQ's flat- sounds SUPERB!!! I USUALLY only mess w/ the EQ when the room makes me NEED to. Sounds SO good- get a good growl outta the P bass thru the V4BH in the 'sweet spot' - near Overdrive...dig in & U get a natural power tube OD, play softer or roll back volume on bass & it cleans up beautifully!!!!
Seriously, one of my professors made a comment once that true tone comes from "within", not knobs, switches or effects.
