Got a Hamer Studio (Korean) from an older gentleman that had a stroke and could no longer play. He needed the $$ to cover medical bills. The guitar is in good shape. Just needed a good cleaning and a couple of weeks in the garage to air out since the gentleman is a smoker. Now that most of the smell is gone I am going through it. Need help to make sure the guitar is wired properly. This is what the electronics look like: I think I found the wiring diagram for this type of guitar (it's all foreign to me): Is the guitar wired correctly? There is a small toggle switch that really does nothing when playing (at least I can't tell the difference). The volume(s) and tone knobs seem to work although they are dirty and scratchy. Don't really know anything about wiring so any help is appreciated. Here is the front of the guitar with said switch: Thanks!
