hey man, can you help me? I bough an used Parker P38 and it is loaded with a Seymour Duncan Humbucker pickup, but, the problem is, when I use the piezo, it sounds great but, when I try to use any pickup or the blender, I get a lot of hiss and it's not ground, 'cause when I touch any metal part the noise is not removed... please help! (sorry for my bad english) thanks a lot man
