Ok so i have an AC30 and i want to get a minimass to put in it so i can play at lower volumes(Its just a 1x12). I heard that i have to make slight changes to get the minimass to work on an AC30. What would i have to do to put a minimass in and how much would it all cost. (for a tech to do all of this, i dont trust myself to mess with an AC30)

i posted a question in another thread but i didnt want to ask another and hijack it.

Thanks for the help guys!
