combo amp start making noise....

[Bullet79]

It was fine before... kustom 12 gauge combo...bedroom practice amp.... never touch '11'... now it start to hum/hisssssss even with a humbucker..... i'm using DiMarzio cable...



16W with 12"speaker... not bad for a bedroom amp...

Have you tried troubleshooting? In other words, try a different cable, try a different guitar, try plugging it into a different outlet...

What is the sound like? Hum and hiss are quite different. Does it happen with the guitar volume turned all the way down? Does it happen with more gain or just all the time?

no its not the guitar ...or the cable... the amp just making noise...(grounding issue type noise...)on CRUNCH channel.....
its like a single-coil noise hum/hisss ... (even with humbucking p/up guitar..it stilll making that annoying noise....)

why it suddenly happen...??

My first guess is a solder joint on a control,or a filter cap has gone bad.
Both have happened on my Crate amps.
Also my little Crate had a bad hiss that went away when I replaced the plug with a good 3-prong one.
As someone who owned before broke off the ground lug.
It was like getting a new amp for the cost of a 3 prong plug (5$ at Ace)
Do you have any troubles with your house electric spiking,or such ?
Any static discharge from carpet when you plug in the cable ?
Its a very nice looking amp,
