So I've had a custom 5 string B-5 fretless Carvin bass for around 8 months now. My problem is that I am not satisfied with the tone that I have with it. My rig that I run through is a Carvin B 1500 amp and a Carvin BRX 10.5 Neo cabinet. The bass also is a dual humbucker and I'm using stock Carvin strings. I put the gear down because I figured it might help. So, is there anyone that can give me some tips on having a good fretless bass tone? Yves Carbonne and Michael Manring are two of my favorite bass players with a good fretless tone. They've got similar tones I believe. Also, it is a lined fretless bass that I have.
