Hmm... After seeing the number of instruments you guys have, I'm not sure I can hold my own. I've "only" got 7 basses, a double bass and 2 guitars... I am only 20 though, so maybe I'm not doing too bad!

Squire P-Bass (Jazz neck and J pickup at the bridge)
Ashbury fretless acoustic
5 string:
Cort JP-5 Signature bass
Line 6 Variax Bass
