I've been playing the bass since for about eight or nine years now, and I dabble in playing the guitar a bit (although I'm fairly terrible at actually playing, my technical knowledge is good enough. I only picked it up really for songwriting and working with guitarists). I play the harmonica too, I originally just picked it up because there was one lying around and I wanted to play The Wizard, but it's good fun. It's nice having an instrument that you can just carry around everywhere as well, makes for an interesting party piece.
I've got a 2010 Fender US Jazz bass (sunburst w/ tortoiseshell pickguard), a 5 string Ibanez electro-acoustic bass (can't remember the exact name) and my old Peavey International bass. It's cheap as hell, but it's actually quite good for slapping on.
I've also got a Squier Vintage Modified Jaguar (fiesta red), it's pretty sweet, but I'm thinking of getting a proper Fender (I'm a sucker for Jags, Jazzmasters and Mustangs). Thing is, all money going towards a new guitar means money away from a new bass, and the bass is just better. I'm looking at getting a 5-string Jackson or ESP as well, the Jazz isn't really suited to metal and I need the extra string. Mind you, there's a whole list of basses that I want, doesn't mean that I will ever get around to buying them all. Ideally I'd want a 5 string Jazz (or Jag bass) with EMG active P/J pickups, but unfortunately Fender don't seem to agree with me that this would be totally awesome.
