How do I set up the "balance" during jamming?

Once I was jaming with my friend~ I am playing a Fender
and he was playing a Fender bass guitar~ we tried to
jam Blink 182's song~but it failed, cuz our sound were
horrible~ sometimes my guitar sounds too loud~ or his bass
sounded flat. Well my friend told me that the "balance" was
not right?
So could anyone tell me that how do I adjust the amps during
jaming? and get a nice and neat sound?

well...what you need to do is make shure you have a bass amp and a guitar amp. Do not run both guitars on one amp or it will sound like **** hitting the wall. Try to buy a 30 watt amp,that should cut it. As for a bass amp your friend could get a 15 watt amp it should be loud because the bass has more bass than a guitar so bass amps dont need to be that loud unless your playing a big place.

hope this helps

try to get a friend to stand and listen, and tell you who should turn their amp up or down. Of course, if his bass sounds flat,t hen it could be he said the balance was bad to try to cover the fact that he is a bad bass player...
