I'm a relative newbie to DB, although I've got a pretty good gig doing it. I'm playing an Englehart M1 ply bass with a Realist or BassMax pickup, and lately I've noticed that the sound is sort of "boxy". I'm not sure of another way to describe it. No real richness to the sound. I've also noticed slight imperfections of the way the bridge meets the top of the bass (gaps of .5mm or so). Am I just getting a more critical ear, or does the bridge fit contribute to a less than perfect sound? How can I tell the difference. Should I stop listening to John Patitucci and Christian McBride? Should I shut up and color? Should I seek therapy? An unrelated question: I was surfing the net and found a website that sells endpins for Arco and Pizz styles. Is this snake oil? Can one endpin style sound better for a style of playing? Thanks for your patience.
