I just bought the JTV-69s and love the magnetic pickups. However, I would love to have the option of running the bridge and middle pups together in series, a pretty standard tele mod, and also done on strats. While understanding that this would probably void the warranty, is it even possible? I don't know what's going on under that hood.
Also, I see wiring diagrams for the JTV- 59, 69, and 89, but not for the 69s. How would it be different from the 69?
