Hi, Just got an Eric Clapton Artist Series from a collector from what I know. That is, the previous owner bought guitars and preserved them intact without playing. However, when I was setting up the guitar, I found a kind of white powder inside (I know what you're thinking) that I presume to be talc for preserving components from corrosion. In fact, the springs in the bridge look like brand new after 10 years. Also, the components behind the pickguard look perfect. However, we know that dust affects potentiometers, and if the talc has some conductive material, it can lead to malfunction of the Clapton strat's preamp. In fact, the mid-boost pot seems a little bit unstable... I have to play with it a bit until it gets properly adjusted, otherwise the guitar becomes quiet. My question is: what do you think? Should I remove the talc? Are these potentiometers easily replaceable? Thanks in advance.
