ok...now i got a gibson costom guitar, and an amp thats from my dad. now this is my question...i want the amp to hear like a punk rockish kind of sound when im playing the guitar...and i cant do that for some reason probably because i dont know the settings for it .do you guys know where and what volume setting should i put it to make it hear like a punk rockish soundheres the problem, my amp is not made from marshall...right in front of the amp it says "Sunn" so my other question is that if all the guitar amps sound the same?
