I have a Musicman Sterling that I couldn't be happier with. I've got the action at about 3/32" on the E string and 2/32" on the G (12th fret). That's not bad, but I wish it were lower. My other bass is fretless and because you can take fretless basses looooowwww I've probably become spoiled. Anyway, I do like low low action - even though I play moderately aggressively. If I spend the big $$ for a boutique bass (Lakland, Sadowsky, whatever) - does it accomplish that for you? It's not really about the sound for me because I love the sound of my current basses.
