i just got the traynor yba 200 in today and it is not loud enough for me at all. i dont care about clean headroom, i want the grit, but still, cranked up all the way it is barely even worthy of the title loud. i am running it through an old 70's Earth 2x15 cab. i dont know how many ohms the cab is. i looked at the back of the speakers and they didn't say anything on them. im really up set because i could of paid 100 bucks for a crappy guitar head that sounded more how i wanted it to than this and was twice as loud. whats wrong here???? also, is it true that these can safely go down to 2 ohms?
