Naw - the onliest things I've done electronically are add a jumper so the 2nd Tone works on the bridge as well as the middle p/up, and add a mini-toggle to cut the neck p/up on independent of the 5-way for all 7 combos - and it worked fine, in the same place with the same amp & cord, after that. My old friend & former next-door neighbor came by to run my snowblower this PM (I being too gimped to do so these days), and he - drummer, keyboardist, guitarist, bassist, and serious tech guy - said that when he was in the 'hood, one of the 3 radio stations within a mile of here would come in on his Leslie (interestingly, the farthest one), but he has no idea about the buzz.
Just to make it more fun: The computer I had when we moved in in '06 would pick up a Catholic station - even when the speakers were off; I had to unplug them. And there's no Catholic station anywhere near here..........
Peter (whose parents would tell him the lord was trying to overcome his heathen ways - except they'd think he'd do it with a Methodist station......)
