What is this loud static coming from my amp?

Question

when i turn my amp on it makes a loud static noise, and sometimes a buzzing too. i can still play guitar with it but its really annoying. it is a lyon 12 watt amp

Answer 1

These can all be caused by a bad connection.  Check all cords and connections for good contacts.  A loose or bad ground connection can cause buzzing or humm.  

If it's an older unit, old solder joints could be going bad and need resoldering.  In older units, a capacitor could be going bad too.

Start by checking all connections and solder joints.
