A fifth person with a recommendation for Damnation. I should look into this pedal brand, never played one of their pedals.I have since pulled the B7K off the board and will be replacing it with an Empress Bass Compressor into a Damnation Audio MBD-2.
You make good points on chasing the tone of those pro metal bassists versus own personal preferences. And to get a good clean tone and build up on that.
I've been thinking by participating in this thread. I'll probably never join a band and go gigging again. But hypothetical; if I were to be in a band right now and we were doing covers of the bands listed by the OP (80's speed/trash metal to 90's nu-metal), I would go fretless with a rather clean tone. It would be my take on the music. Same dish, different seasoning. Unless my hypothetical band-mates want more dirt then I can slowly open the tap of overdrive if needed.
