Lewguitar said:I've never understood exactly what it does but I do know you need two out of phase humbuckers and that it plays those two off of each other for a progressively thinner and more nasal tone. I love BB King but that pinched out of phase tone is not the tone I want for my own playing. I removed the varitone from my own ES-355 and put the two humbuckers in phase so it sounded more like an ES-335.

BB did use it. He set it on position 2 or 3. I have one of BB's Lucille's here (belongs to a friend) and it sounds just like him with those settings. None of the settings are out of phase.
