You know you're a guitar player when your girlfriend says she got a new g-string and you ask " Is it nickel-wound or bronze phosphorous?"

I don't know of any amp that is designed for both guitars and basses. This looks like it is just for bass.

you can use a bass amp for guitar but dont use a guitar amp for a bass. that would be not so nice. It should work if you want it for your bass and guitar. and for your guitar just buy a nice distortion pedal when you want some dirty tones.

Buy an old used Fender Bassman, cheap and it's got damn good tone, and works for both.
