Probably convenient for dave as he doesn't have to worry about the sound settings.
Forget about the reasons and the treasons we are seeking
Forget about the notion that our emotions can be swept away, kept at bay
Forget about being guilty, we are innocent instead
For soon we will all find our lives swept away
yeah dave uses a non factory sound system and he always tapes over them to make sure he doesnt mess up the settings while playing on stage...that would definately be a problem
actually, those knobs are useless to Dave. Since he put in a fishman pickup, it makes those knobs on top completely superfluous. The gibson preamp doesn't work with a fishman, so he can spin those wheels all he wants but it won't change his sound any.
