Well, let's see ... it's been four years and I need to rearrange a bit. So here they are again, in order of decreasing age.
Nice list Munjibunga!
Mine in order of degree of "realness" (number of strings)
Conklin GT Bill Dickens 7 (Pleked)
Modulus TBX 6 (Cuts the mix like NO other bass)
Alembic Epic Fretless 6 (Hey, Alembic says it all)
Ken Smith burner 6 (Typical KS quality... to die for)
SX Fender-clone 6 (x2 fretted and fretless does this count as one bass? These "chungerized" basses kill!
Carvin AC50 Semi-hollow acoustic fretless 5 (Too cool for words)
G&L L2500 fretless 5 (MIA... say no more)
G&L Tribute L-2500 fretted 5 (With Single coil mod)
Fender MIM Deluxe V (Hey, it's a real Fender!)
OLP MM-3 5 (Passive makes it a hassle but CAN be "dialed-in")
I really hate to see my SX collection cut off the bottom of the list because I really, really like them, but hey they are just bar basses! Same goes for my Carlo Robelli 8 string. Too cheap. Too weird for the list, but I love it.
