Don't use JB weld in a switch, it's often metal filled it could cause problems, tone controls are sometimes in B+ circuits so it definately would there if anywhere. Use regular two part epoxy, preferably the type that takes 24 hours to cure. I don't know what the fixation is with using J.B Weld in everything, it's just a high heat epoxy, but don't use metal filled epoxy in electrical equipment.
