I'm having trouble generating the volume I *think* I should be getting out of my bass. I'm new to this game, so I'm looking to the experienced DB players on the list for assistance. My bass is a newish Strunal plywood strung with Helicore Pizz Mediums. When it arrived, I had a local luthier work on the string height and bridge shape a bit and he commented on how well the bass seemed to be set up "out of the box" in comparison to others he's worked with. The volume increased a good bit when I installed the Helicores, but I'm still having trouble hearing myself over an acoustic guitarist (who doesn't seem to me to be playing especially loudly). I'm planning on playing bluegrass and folksy stuff, and I can imagine that I'd be pretty lost in a trio or more. I'm working my right hand as hard as I feel I should, but still not enough volume. I owned a '50s Kay a couple of years back and I don't remember having this problem. What factors are involved in double bass volume increase or decrease? Any particulars I should check out? The luthier who worked on the bass has a good reputation for work on acoustic string instruments although not particularly for double basses. Could he have missed something like a soundpost installed incorrectly, etc.?
