I took my amp to a guitar center and the guys there knew absolutely nothing

I said "hey i got one of these old SS-140C's and im pretty sure theres something wrong with it. either that or i have really worn out cab.
he takes me to a mesa cab. and i play and as usual, hair metal tone

and you can quote me on this "everything sounds fine, its sounding how it should, blah dee fukkin dah, i get reamed by john adams zombie corpse flying at my asshole on a bicycle made out of ham sandwiches"
so he was an idiot.
he couldn't help me at all, so im takin it to a local music repair store where i should have gone in the first place
