I have a 5-way switch in one of my Teles adding series and parallel phase. All these tone are quite usable and distinctive. The only option I haven't tried is where the pickups are wired in series and out of phase. First of all, has anyone tried series out of phase and is it worthwhile? Secondly, it will require a six-way rotary switch (4-pole) or push-pull pots. The push-pull pots I've seen are much lower quality that the regular CTS pots I would normally use so I'm leaning towards the rotary switch in the tone pot position and using the 5-way selector switch as the tone control - or getting a blank plate and drilling three holes for volume, tone and rotary selector. Thoughts?
