I'm 14 and I have THE most stubborn father. I need help to convince him I need an new amp. Right now I have a little pignose and he thinks I'm just fine with that. for christmas I want a new marshal amp. not a big one just a 30 watt amp, and he thinks that would be okay if I was in a band but, that wouldnt be if I was. Can someone help me on what I should say to him? Please
