    I installed keystones and had an issue. I posted about it a week ago. Thought it better to have a local shop fix it right. It works now, but a few things jumped out at me instantly. I removed the controls and found he installed a .047 cap and it lost the sparkle high. The vol pot is a linear - I will need to play with it more to see if I like it. But the bigger issue the middle position is way louder. Thinking he has wired these in series. He has the cap running from the tone pot to the third grounded lead on the volume. I've never seen that before. Can someone tell me what a 3 way middle in series would look like so I can confirm my suspicion?

    I will ask him to switch the cap to a .022, not sure about the vol pot, but definitely want my standard middle position back.

    Let me start with saying I'm no expert and take everything i say with a grain of salt.

    1. With the tone control maxed out you shouldn't be able to hear a difference between cap values, so it might be imagination or he fiddled with the pup height.

    2. Pot taper is subjective stuff. You got to find out yourself what you like better.

    3. I can't tell you how a 3-way with middle position would be wired like, but series in general will sound louder and beefier than any of the pickups on their own. Almost like a twang HB. If it's a bit quieter than the other positions you have your standard parallel wiring. Maybe the middle position was extremely quiet and nasally before (alias out of phase wiring) and he 'fixed' it to in phase for you? More detailed info required here.

    4. It's a common way for Fender to wire caps in their production teles. Nothing wrong with that.

    Hope this helps.

    My colleague Chrom pretty much nails it. I would only add that if you're not happy, talk to your tech about it. Be nice, and give him the opportunity to make you happy. Most of these guys are good at what they do, and are anxious to make your guitar play the way you want it to.

    I've got a set of Keystones going into my current project, and am anxious to hear them play.

    This shows a 3way switch wired bridge, middle (series) and neck. It also shows a 4way switch wiring.

    I doubt if the tech just "happened" on the different wiring by accident if indeed it's wired for a series middle position. Sounds like something else is going on as pointed out in the previous posts.

    Give the guy a chance to look at it, might be an easy adjustment or fix.

    I like the tech. He's a good guy. We talked about series and maybe he assumed that's what I wanted. I think the .047 darkens sound considerably.

    Wiring the cap to the 3rd lug of the volume pot is fine. The pot and cap are connected in series, and it doesn't matter which comes first. The 3rd lug of the volume pot is a ground, and the tone network is connected to ground somewhere. It doesn't matter much which ground is used.

    I often add a resitor to my volume pots to make the taper more like a linear pot, which gives a wider sweep as I roll down. Try it, you may like it.

    Like chrom says, with the tone control wide open the cap is totally out of the circuit, so it won't be making the guitar darker. Even if he did use a .047uf cap (the standard value for a tele with 250k pots, btw), it just means that you get the same tone reduction with less rotation of the pot.

    Drob if the middle position is wired in Series that itself will darken tone when Bridge and Neck are played in combination. It may be that which you're hearing as opposed to that change in cap values.

    Just a suggestion but maybe you should ask your tech to install a 4-way. I have Keystones in one of my Tele's with a 4-way and I can honestly tell you that they have a killer tone in Series. Even better than the Nocasters I have in other Tele's. More transparent and defined and with more character.

    4-way switching with those pickups will really give you another very nice useable tonal option whether you're using .022 or .047 caps.

    This is why if I do some work on a friend's guitar I always give them a sheet of paper with everything listed and the reasons. Takes me five minutes to write but it keeps everything clear for all concerned. (I'm not a proper tech but can do set ups and some repair stuff.)
