major feedback prob

[incredibleindia]

hi guys i have this this major feedback problem. even with a clean setting on my boss me 50 i'm getting feedback, least to say when im on distortion. even when i'm not playing there's this constant hum/fuzz/whatever being emitted from the amp.
i thought it was a problem with my cables but i changed all of my cables and though the feedback is slightly better there's still a noticeable amount.

and i'm frequently getting electric shocks s when i touch my strings/resting my hands on the bridge.

i'm using a marshall AVT20, boss ME50 and a prs custom 24

any suggestions on reducing the problems would be greatly appreciated thanks !

Im betting on your plug for the amp is 2 pin, ungrounded. Change to 3 pins ^^

its 3 pin i dunno i dont seem to have this problem when i use battery supply for my pedals. happens more often when i use electric power on the pedal.
as for the feedback problem i dont really have any idea still

The problem is with the adapter.

Using batteries gives you clean DC voltage, that's why there is no hum. The hum you are hearing is coming through the AC adapter as it is not rectifying (converting to DC) properly. That would also explain the shocks you are receiving, if they only occur when you are useing the adapter (the adapter has two pins).

If you are not using the stock adapter then try that. Otherwise there may be a problem in the earthing of the power supply within the pedal.

Hope this helps.
