soo i got a new amp for christmas its a laney hardcore max if that means anything..ive never heard of it before but anyways i plugged it in and turned it on it seemed to work fine until i plugged my guitar in and no sound was coming thru..so i messed around with it a bit and it seems it only kicks on when you have it turned up really loud which kind of hurts the ears when it surprises you when its max volume and your hitting the strings. anyways i was wondering if anyone could help me find out whats wrong and fix it? thanks.

the hardcore max is a bass amp.........not sure if it`s a valve bass amp, if it is you gotta give the valves a couple of minutes to warm up.
