well, bad earthing was my first theory, i checked the wiring and there was some bad connections, re-soldered them, thing is, i cant see any connections to the metal plate witht he pots on, which is why i changed my theory to picking up wobulations (it happened on a regular basis in the labs last eyar when i did electronics, but we had a scope, a little easier to fualt find with an oscilly)) and its cured by using a decoupling capacitor, i cant see why adding in the impedance of the capacitor would make any difference, am i wrong? im going to maplin to buy some tubes and a set of capacitors, ill experiment after iv resolered all the wiring.
i think the strings do effect it aswell, and the plate that the strings are attached to aswell, but strings to lesser extent.
