ok, i have a 50W amp with a 12" cone. It is loud enough so that i can be heard in band practice and i am happy with the tone it gives me, but i am not sure sure whether i will need a bigger one if we ever get to play live. i believe it is possible to mic it up and send it to the PA, but will this reduce the sound quality? At some of the smaller gigs i have been to i have noticed that the support bands all seem to use the same amp, are venues likely to have their own amps/can i get away with this? i am i likely to crash and burn attempting to use this amp (carlsbro bassline 50) unsupported? we haven't really got much lined up except a gig in school in a relatively small room. I really dont want to spend £400-£500 on the cheapest amp i can afford, but i would also love to be able to perform, any advice welcome, thank you for your time.
