So I was wondering for practising on my own, will 15watt be enough? and what about practising with a drummer? I basicly don't mind paying 150 bucks more for the 30 watt one but I'm wonderign wether the sound will be good since I won't turn it to max volume most of the time... will 30 watt sound better than the 15 watt one even at low volume?
I own the LC15R and I'll let you know right, you're not got going to anywhere near max even when jamming with a drummer. The thing is very loud.

And for bedroom practice, this amp is much too loud unless you're using an OD pedal.
