Well I have been playing my new fretless 34" Pedulla Hexabuzz a lot this week. The low B was flubby, and it did not sing as much as I'd like. The bass came with: B .128 E .100 A .080 D .065 G .045 C .028 I took it up to: B .145 E .110 A .090 D .065 G .050 C .035 The bass sings great now, the low B is now fantastic. Basically I have raised the average from 39.78 PSI to 50.81 PSI. The string to string balance of my custom set is far better than the original strings. Moral....if you are unhappy with you bass, try new strings and no .145 is not too thick.
