I've just dropped a pair of new SD Quarter Pounders into a Tele with a 4 way switch. The rhythm pickup has a coil tap. My problem is that positions 1, 3 & 4 all sound great, but in the mid position (2) the power drops a significantly. I thought it might be a phase problem, although both the pickups are S Dunc's so should be in phase. When I reversed the phase on the bridge pickup it was worse, with positions 2,3 & 4 all having weaker signal; so I've gone back to the original connections. The guitar is wired in the usual way for a 4-way switch, has one vol + one tone pot (250k). I'm not a pickup expert, but have modded another Tele of mine before in a similar way (though only with a three way switch) without having this problem. Any ideas on a fix for this?
