A loud buzz is present in the guitar
signal
❏
Does the buzz decrease when you lower the volume of
your guitar?
→ If the buzz decreases when you lower the volume of
your guitar, it is possible that the pickup of your guitar is
receiving noise from a computer or a display screen.
Move as far away from the computer as possible.
Sometimes this problem can be solved by grounding the
chassis of your computer, or the grounding connector of
your computer's AC power supply. You should also
check whether there is a device nearby that produces a
strong magnetic field, such as a television or a
microwave oven. (p. 5)
