Been reading the board for a bit now but this is the first time I have posted . Well my wife and kids chiped in a got me a new amp for a present back in september . I took it to band practice last night dont get me wrong I really love my marshall but this thing is kinda cool but at full volume i get a bit of feed back so I was thinking if i changed to some lower gain tubes in the preamp would that help ? and also how do i find out witch tubes are the preamp and the phase inverter sorry about the long winded question but well i have played guitar for several years but dont know alot about the tech end of it .
