Pre-Wired guitar harness | Telecaster 4-way harness kit | LEFT HANDED
I usually make harnesses to order, due to the variety of spec options that could be chosen across the whole range. The turnaround time for a harness orders is around 3 working days depending on quantity of orders in at the time and your order will be updated accordingly when it is dispatched. This turnaround time doesn't include the transit time. Thanks for your patience whilst I get your harness made!
The Telecaster is an iconic instrument, that defined a brand, inspired so many musicians and set the bar for the electric guitar moving forward. I want my Signature Series wiring harness for this legendary guitar to earn the right to be a small part of that through a choice of quality components and respect for it's design. This schematic is the super popular 4-way mod, retaining the traditional 3 position Telecaster sounds but with an additional position putting the two single coils in series for a chunkier sound, and the parts aim to bring out the best in your telecaster's tone, and aim to do so for many years to come.
Not sure whether Left Handed/Reverse audio taper pots are 'right' for you? Check out this article I put together addressing the subject, and hopefully it will help you find the correct choice for your playing. HERE
I have intended for my wiring harnesses to be as simple as possible to install to your Telecaster, as well as writing in depth fitting guides, how-to instructions documenting the step by step process as well as a simple to follow wiring diagram.
The parts I use, in particular the pots, are CTS branded pots which are imperial measurements. If you're fitting this harness to a far east built variant for example such as a Squier or similar, then you may have to widen the holes in the control plate to accommodate for these imperial measurement pots. Or alternatively, purchase a new control plate that is already suited to the US spec components.
For reference, the CTS pots I use in this harness have a shaft diameter of 9.52mm.
As the Left handed kits have the option between using Right Handed or Left Handed taper pots, there is a slight difference in the pots used to achieve either option. The RH taper pot version uses CTS Solid shaft pots which have a solid shaft diameter of 6.35mm. Whereas the LH taper pot version uses CTS Split Shaft pots which have a split shaft diameter of 5.95mm. If you are planning on using traditional grub screw fitment Telecaster control knobs for the LH taper split shaft harness, then you will also require a pair of additional brass conversion sleeves to convert the 5.95mm split shaft to 6.35mm solid shaft. You can order those HERE
You may also require new control knobs to fit the CTS pot 'solid shaft' diameter of 6.35mm.
If you do require a US spec control plate or control knobs, we do carry a selection of popular options in stock and they can be viewed in the hardware & plastic hardware categories on the store.
Centre to centre measurements between components are -
Centre of Switch to volume pot - 40mm
Centre of volume pot to centre of tone pot - 64mm
These measurements for my templates were taken from a USA Fender telecaster control plate.
Fitting a 4 way telecaster harness is a little different to a conventional 3 way harness, in that the neck pickup could need modifying depending on how it has been made by the pickup manufacturer. If it is a standard, two wire pickip, it requires an additional ground wire adding which allows for the series position and the small ‘jumper’ wire snipping/removing. I have written a guide to do this HERE but if you are at all unsure about doing this, I would highly recommend supporting your local trusted Tech to carry out the modification for you. This is also shown on the wiring diagram to follow, but please keep this in mind, correct grounding is essential for this schematic to work as it should.
I have also written a blog article, detailing the steps taken when installing a 4 way wiring harness! That can be read HERE
Also, the 4 way switch has a slightly increased throw angle, sometimes requiring a wider slot control plate. Not all control plates can accommodate for a 4 way switch without minor modification. Some players file a very small amount off the slot in the plate, and some players prefer to file a little notch in the 4 way lever. But it is worth baring this in mind, the 4 way mod may require extra attention as noted here.
With or without Treble Bleed?
First up, what does it do? A Treble Bleed kit takes the 'high' treble tone frequencies out of the circuit at the volume pot, and puts them back in the circuit as the signal leaves the volume pot. This means the treble frequencies are prevented from naturally bleeding out of the circuit as your turn your volume pot down. The result is a smoothed out treble and a more uniform tone from 1 to 10. Reducing the treble drop out as the volume pot rolls off. Some guitar players wouldn't be without a treble bleed, and many have never used one on their guitars. Truth is, it is very much personal preference. If you like the idea of retaining treble as you roll your volume pot down, then a treble bleed is for you!
