hi, i have a digitech rp350, when i conect it to the randall produce a noise what can i do, without the rp the amp doesnt produce the noise
Are you plugging the RP into the same outlet as other equipment, like a computer or a lamp? Even your amp could cause this. Then again, the RP may be just prone to noise.
im plugging it to amp input, the same of my avt50x, but the marshall doesnt produce the noise
