Maybe it's just me . . . depending what day it is, either I DON'T sound good and my tone sucks, on a great bass and amp, or I'm just NOT playing very well, despite the fact I set my own bass up myself and the playability is just fine.
And this is on the same bass and amp with all the knobs in the same place: Yesterday I was a hero, today I'm a zero ! ! And I've been playing for thirty years ! !
The eternal struggle . . . . playability and tone is all well and good, but some days it just doesn't matter if my head and hands aren't talking to each other.
