I bought myself a new guitar some time back, an Ibanez RG421 (hardtail) on closeout from the US... When I received it I noticed that when I turn the volume knob to 0, the guitar is still not silent, it's as if it was turned to maybe 2 or something on another guitar. I thought that wasn't big enough of a defect to send it all the way back to the US for (I'm Swedish) because it works very well other than that. However, I'd like to fix this if possible, but I'm rather clueless as to how..? Anyone care to offer me hints?
