Legacy 3 buzzing - Reverb

Postby Muchiutti » Tue Mar 13, 2018 2:18 pm

I own an Carvin Legacy 3 100W head.

Yesterday was playing at low volume, then a loud buzz started at a level that cover the sound.
The buzz goes away when the reverb pot is zeroed and I can play normaly. The buzz come back if the reverb pot is at any point different of zero, even the reverb is on or off.
I have some electronic skills but could not found a schematic for this amp and I have no idea what is causing this problem. Can you give me any information that help me?

First step in trouble-shooting any guitar amp, whether it be tube or solid state, is making sure everything's clean with a non-conductive contact cleaner. That includes the pots and switches.

Next would be to make sure any and all cables that can be unplugged from inside the amp are unplugged, are re-seated, and snug.

Beyond that, others will need to chime in...
