My 18 year-old daughter has picked up guitar and has already far exceeded her Dad's abilities. She is currently working on the second solo in Comfortably Numb.

We bought her a Squier Telecaster for Christmas last year and this year she wanted a bass, so a Squier Jazzmaster Bass will be under the tree.
I don't know anything about bass amps. Any suggestions for a cheap, but decent bass amp? Small, solid state combo would be preferred. Main use is goofing around, not gigging.
