So I get this really great lightweight (6.4lbs of swamp ash goodness!), big necked beast of an Esquire off of one of the Forums, and it turns out that someone formerly had a neck pickup in there. In order to “restore” the guitar, apparently the solution was to simply remove the neck pickup and replace the Esquire pickguard. We all know that Teles and Esquires were all cut the same way – with potential for a neck pickup if you replace the pickguard…
Anyway, the guitar didn’t work because Esquires are just not wired the same way! Solution: I set about to find a useable wiring schematic for an Esquire. Seymour Duncan has a great resource, but there are lots of other ones on the web. Back in the early 50s, an Esquire was wired with an “always on” .047 micro farad cap in the 1st position (or sometimes 2 of them!), a working tone pot in position 2 with the same value cap and then a straight through “no cap, no tone pot load” in the back position of the switch.
I could discuss the merits of caps of different voltages and different types – ceramic disk vs paper in oil, for example… let’s just say that there is a difference (contrary to what some people will say) and you want an audio cap of a higher voltage – in my experience.
So, in wiring this Esquire, the main thing is to get the “always on” cap to be usable – rather than the bassy muffled tone of the older Esquires. I used a nice .047 paper in oil cap for the tone control setting – where we can control the amount of tone roll off – but for the “always on” position, I used a .0047 cap – note the extra zero! Using a .0033 cap is also popular, but the point is to get a lesser treble roll off – so it’ll be great for rhythm playing! The other thing… since you don’t have to remove the strings to swap caps, I simply left the control plate open and in seconds auditioned several different caps.
There’s a diagram on the web that showed me how to wire this guitar so that the tone control was active in the back postion of the switch and the middle was the straight through pickup. This I like!
