he lied to your ass, he probally wanted to trick you into buying something more expensive in an amp. i was using crybaby and rocktek distortion on my gorilla and my fender squire 15, and i had no problem. the peavy blazer has 15 watts and it should sound decent coming out cause my two prior practice amps were like 15 and 20 watts, and it should hook up the regular way with no special crap adapter. i think this is a simple case of the guy trying to squeeze some more money outta you for an amp i think.
