Original Marshall ShredMaster - noise problem.

[Samy]

I have one Marshall ShredMaster to debug, it´s screaming like a pig when the Volume and Gain are at max. .
There are some noise problems too besides the squeal, but when the Vol and Gain are at high, i thing these problems are related.
Looking at the components, those caps are giving me some creeps ! They are extremely small and i don´t know if they are good quality ...
I must haunt the problem but i need to know if anyone have encountered this problem too.

Thanks.

  Nope, just problems like that.
  Sounds like loose wire problemaybe  Could be something else..
  They are extremely small and i don´t know if they are good quality ...
  Size doesn't really tell anything about quality, I would guess HQ caps were used.

No loosed wire. There is only one small flat cable and two battery wires .
I´m thinking using a audio probe, but i don´t know if this will help me in this situation.
I know size doesn´t matter, but i also know that brands like Marshall, Boss, Ibanez, ...  usually use low budget components to save some money...
