When I see my band mates spending several thousands in Yanagisawa or Selmer saxes, a Presonus mixer or a Yamaha Tyros-5, or a Gretsch or DW drum kit, I realize I'm rather lucky to be only a bass player...
Owning 7 basses, ranging from $1,000 to $50, fretted or fretless, 4er or 5er, RW or maple:
2 Fender AVRI's (1P + 1J), 3 MIA G&L's, a Sire MM V7 and an SX P.
I would not part from any of them, they all have their own qualities and I play them equally, even the SX P (that has an incredibly low action, poor tone, BUT ideal for practicing at home).
I have had no experience with a multi-thousand dollar bass, I - poorly skilled - don't even deserve to own an instrument of that value.
