Hi all, long term lurker,
I have a kustom Kia bass amp that came to me making a nasty buzzing noise, I managed to track it down to a switching jack on the input, the amp is now quiet but if the guitar is unplugged the noise is there again.
All the other amps I own, Marshall valve amp, lanes bass head solid state practice amps, make a little more noise when a guitar is unplugged but not on this level, this is a really harsh buzz which alters in level with the Channel gains ,the same thing happens on both channels.
I will try to post a copy of the schematic
Any help would be great.
