I'm currently trying to wire up an old Ibanez like a JS1200, but have a question about the coil tap switching on the tone pot. The diagram shows the tone capacitor going from one leg of the pot to both of the nearest switch poles, while also grounding to the switch case. This totally makes sense in order to coil tap both pickups... However, I pulled the back cover off my 2008 JS1200 to get a good visual on how they did it and the capacitor goes through both switch contacts, but is not grounded to the case. My coil tap works fine, very noticeable change in sound... So should I ground the two switch contacts like it shows in the diagram below?

I noticed my js24p was wired differently than that diagram as well. I replaced the pots because they were too easy to turn, I like a bit of resistance when I turn a pot. I used that diagram to wire it. I suppose there is probably different ways to achieve a similar sound. I rewired my custom js, and my js24p like that diagram and it sounds great. It'll make your life easier if you follow the diagram haha. It's an official Ibanez diagram anyways.

Oh good... Thanks for the feedback. I went with my gut instinct last night and grounded the capacitor and two contacts, like in the diagram. I feel much better now, knowing that you had good results using the diagram! Just need to wire the output jack and ground the tremolo and it will be done, hopefully.

I was actually surprised when I removed the cover on the JS1200 at how shoddy the wiring and solder work was... Grainy cold solder joints, long melted sections of wire, grounds tacked here and there and everywhere. I guess I expected to see pristine wiring on a high end signature model. Although I did buy it used, so maybe the previous owner had pickups swapped in and out. It has always sounded great, but I may try to clean things up. Now that I've seen the mess it is stuck in my head.

Edit... Almost missed the pun of the day - "I like a bit of resistance when I turn a pot." LOL!
