Re: I want to ride my... 60 cycle
Well, I switched back to a straight wiring for the Hot Rail and used the push/pull pot to simultaneously split an HS-3 and HS-2 in the same guitar that houses the HR... Much better!!! I believe that the Hot Rail may had developed a ground loop problem due to the series/parallel mod-- no big deal as the modification just didn't offer that much. I'm getting a wider array of useful sounds with the new mod.
As for the ground problem, there was no hum in the other pickups, so I'm pretty sure it was a flaw linked to how I wired the Hot Rail to the pot's switching options.
