I think I started playing bass in summer 2003, don't quite remember.
I was the worse of two guitarists, so I had to pick up the bass. :P
I play bass in a band called Auer (taivaanautio.net) and used to play in a prog band called Vitkaste.
Also a lefty guitarist.

Basses:
-Fender Japan Fretless J-Bass
-Tokai P-Bass
-Warwick Rockbass Corvette 5-string
-Carvin LB76 (I think) 6-string
Amps:
-Monster Mosquito 60W Head
-Hiwatt DR103 100W Head
-Propably self made Fane 2x12 and 1x15 cabs (Latter is at least 30 years old so I don't know. Was made to match Hiwatt though.)
-Peavey 80W combo (Don't remember what type. Haven't used it too much.)
-Roland Cube60 (old one)

And loads and loads of effects. :)
