not exactly sound proofing but juz acoustic foaming. cost me less than 100 bucks. those pattern foam i got it from one of the softies here, Jaybon. he is selling each piece for 5 bucks if i could remember. the bugera i got it online. change the stock 12ax7 to jj tubes. more dirty sounding more gain. bias the power tubes hotter to get the tight chugging sound. quite a versatile amp i should say. plug in a strat blast the reverb and u can get dick dale's mirsirlou tone on the clean. the crunch channel is the one i love the most. from U2 dirty sound to some seroius death metal crunch. the lead channel.... need me to say more....? u have to try it to know more. but i know nothing beats the hi-end tube amp. well.... dat all i could afford.
