No. It is not ok. You need a large double bass set- up to do metal the justice it deserves. If your guitar players aren't using full Marshall stacks they need to get with the program. Doesn't anybody watch MTV anymore? You can't play metal looking like a group of hillbillies. Pretty soon you'll be doing gigs at the Grand Ole OpryI have been using a 3 piece for about 6 months (snare/bass/tom-tom) and before 3/4 months i bought double pedal and started playing blast beats(16"notes 200BPM+).
So i'm curious is it okay to use a 3 piece with 3 cymbal (classics setup hats/crash/ride) to play that kind of music(death/deatcore/black/progressive)?
Look to George Kollias. That's what you want to look like
See what I did there 😳
