I have a Genz Ben Shuttlemax with two channels, the second one a "tube" tone channel. I have been branching out a bit into slap bass, but it's pretty new to me and I'm far from proficient. When I slap, the volume I produce is a lot lower than when I fingerpick. So I'm thinking I should set the settings on the tube channel for slapping and at least make it louder or more gain heavy. My question is, what do you slap pop guys emphasize in your settings? And why do I produce less volume slapping?
