I bought one of these guitars, and overall it's great, the problem I have is the G string is much louder than the other strings when the piezo is engaged. I'm wondering how I can turn down the individual string volume. I looked on the PRS site and it stated that volume adjustment can be made via turning some screws inside the battery compartment. I assume this is talking about the USA made guitars, because there is nothing obvious inside the SE which would allow me to do that. Would be grateful for any info. At this point the piezo is unusable as all I can hear is the G string droning over the top every chord I play.
