Congratulations - and happy birthday/Xmas too BTW.
The C30 is indeed a great sounding little amp, and I sometimes regret I didn't bought one instead of the Blue Junior. But as you say, it can get pretty loud. Our singer/rythm guitarist has one, and even with our very heavy-hander new drummer he never had to crank it up in rehearsal (can't say the same about the bjr...).
