I'm looking into buying an amp and I really don't know the first thing about them.

I need an amp for home and band practice. I don't plan on doing gigs, I only play with a couple of people now and then.

I have a Roland DAC-15XD (15 watts) at the moment. As you can see if there's a drum involved, my amp doesn't have what it takes to stand out.

Could some of you help me out and suggest an amp.
