hey guys need some advice. recently got myself an Orange Rockerverb50 head. all psyched up and stuff. plugged in the guitar and omg what a clean tone. stepped on the footswitch and i was getting this flat sounding slightly hissy in the background breaking up kinda tone. not at all like how its been described. could it be my cab? im running it through a Marshall 2X12 fitted with V30's. a cab is a cab right? would it make a difference if i was running it through another cab with v30's??. another thing is, i havnt found an od pedal that goes well with the Rocker50. the ocd ver 2 is pretty nice but.... still something missing after spending that sort of cash. any advice?
