I have a Roland Cube 60 and a Schecter Tempest and when ever I turn on my amp I get this horrible buzzing noise. It gets considerably louder when I have my toggle switch on the bridge position and doesn't stop when I play or touch the guitar or anything. Any help?
Try getting a new cable or checking the output jack on your guitar.
Are you playing near a Television, radio, or computer?
swap the cable and jiggle the input, see if the noise changes like said, but dont hand tighten the jack.
