Unfortunately, not all wires are connected to where they should be connected, so the guitar is not producing any sound at all. A number of solder joints have clearly failed, but working out which wires should be connected where will take a while, and only then can I try re-soldering those joints.
The controls are; Master Vol & Tone plus 3-way selector switch (all standard so far). Coil tap and phase mini-toggles (fairly standard options on many Kawai guitars). A 6-position varitone (that's a complex looking little switch!). But then it gets slightly more complex ... a pre-amp with level control and boost/distortion, all powered by a 9v battery.
Inside the cavity we have 3 standard sized pots, 4 mini-toggle switches, a 3-way pickup selector, the Varitone switch, the pre-amp circuitry, the battery connector and a large output jack that allows the battery to be switched on or off. It's a standard sized control cavity. I'm going to need a small soldering iron!
I've spent a couple of hours trying to draw out the "as is" state of the wiring, including the wires that don't get connected anywhere at the moment. Then I'll try to work out WHY they're connected as they are, and how to reconnect the "spare" wires. One day, my knowledge and competence with electrics - even basics like this - will reach the rudimentary stage. Right now, I'm nowhere near that level. So this project could take a while ... stay tuned for updates!
