Schecter Omen 6 Electric Guitar Problem?

I have the Schecter Omen 6 and I play on a squire champ 15 amp. When I play on the clean channel I adjust the volume for where I can hear the guitar good, and when I switch to distortion channel it is so loud it almost blows you away (Expression). I purchased this guitar brand new off of ebay from a dealer in new mexico. I live really far from new mexico, but I found the phone number and explained my problem to them. The man said he can flat out tell me it is probably not the guitar because the humbuckers are made for super distortion, so when playing on an amp like that you will need to adjust the gain and volume (ex. gain= 2 to 3 and volume= 8 to 9 or the other way around) but when the volume is 2 to 3 i can barely hear the clean channel and when the volume is on 8 to 9 that is too loud. He said a bunch of other things too explaining it, but I can't really remember it all. What can I do to fix it. I take guitar lessons every week so I can't really send it into schecter itself because I might not get it back in time. But then I might void the warrenty taking it to a dealer. Is it the guitar or the amp?
