Thanks guys! The amp is fine but i have a problem with the effects loop :?!I plugged a Lexicon MX200 in the loop and...just a BIG BUZZ :( Even with the Master on 0,i get the same buzz.No other sound !I use the Lexicon everyday with the Nomad,no problem.Before i bought the amp,i specifically asked the seller about the loop's condition because many Rebel owners were complaining about theirs (static noises etc..) !(The guy said the amp was in perfect condition but.. he had never used the loop himself

!)I will try again tonight but i wonder why is there such a strong buzz even when the Master is on 0?
