I play indoors,haven't got a band yet, buying a new amp recommendations of watts? I'm thinking of 15. Would 30 be too much for home?
If its just a practice amp then go for 15.
I have a 20 that i use to practice and i usually crank it to about 7 and its plenty loud for practice.
I didn't know they made 1-3 watt tube amps...

I use my 50 watt vox ad50vt at home for practice, and its fine. With a solid state you don't really need to crank the volume.
