stingray > sansamp bddi > svt 4 pro in the last soundcheck i had, i noticed that when i touch the strings / volume knob / tuning peg / anything metallic it's silent through the amp, yet if i take my hands off the guitar completely there is a small - but noticable - buzz... sounds like an small earthing problem, doesn't it? as when i touch anything metal surely i am earthing it? it doesn't affect the sound when playing, as it's too quiet to hear over actual playing of the bass, so it's not a problem. my question is - it's not going to get any worse is it? should i get it looked at?
