Pre-Wired Guitar wiring harness | ES-335, ES-330 & Casino kit | Right Handed & Left Handed


Order times
I usually make harnesses to order, due to the variety of spec options that could be chosen across the whole range. The current turnaround time for a harness orders is around 5-7 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 335/330 is one of, if not my most favourite Gibson guitar design. The 'Electric Spanish' semi-hollow body design is incredibly versatile and capable of some superb guitar tones. I truly hope my harness for the 335 helps bring out the best in this instrument, and hope the subtle component choices I have made help make the install that little bit easier. 335s are a little feared by guitarists when it comes to doing wiring work, due to limited accessibility via the thin F-Holes. I have chosen items like the Switchcraft 'Short Frame' 3 way toggle switch, which is smaller in overall size than a traditional Switchcraft switch, making fitting it through the f-hole easier as well as having a much longer thread length making it easier to mount up once inside the guitar. I have also chosen my usual Pure Tone multi contact jack socket for this very reason too, featuring an extended thread length as standard to help mounting that little bit easier. 
Wired '50s' style.

Left handed choices
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 335/330/casino, 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 Epiphone or similar, then you may have to widen the holes in the body to accommodate for these imperial measurement pots. 
For reference, the CTS pots I use in this harness have a shaft diameter of 9.52mm and I tend to widen the body holes to 10mm to suit.
You may also require new control knobs to fit the CTS pot 'split shaft' diameter of 5.95mm and 24 spline.
If you do require US spec 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 neck volume pot - 48mm
Centre of neck volume pot to centre of neck tone pot - 66mm
Centre of neck volume pot to bridge volume pot - 67mm
Centre of bridge volume pot to bridge tone pot - 65mm
Centre of neck tone pot to jack socket - 65mm

With or without a treble bleed?
First up, what does it do? A Treble Bleed kit takes the 'high' treble tone frequencies that would otherwise be lost whilst rolling the volume pot down, 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 (compared to a circuit without) 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. and there really isn't a right or wrong choice as standard, but more so how you like to control your guitar via the pots. 
50s style wiring already helps a little with treble frequencies through the volume pot's sweep due to the tone capacitor being attached to the output lug of the volume pot. Now, there is some argument against using a treble bleed with 50s style wiring, but I had so many requests from customers wanting it, that it's now an option available and customer response overall is really good so this only further proves that it truly is personal tastes! Some find that adding a treble bleed mod to a 50s style wiring scheme causes an overly bright tone in the lower ranges of the volume pot's sweep, but many of you love that and it helps keeps things crystal clear tonally. Again, you will ultimately know what you like to hear, so I hope this helps guide your choice. 
To summarise, treble bleeds aren't really needed for fifties style wiring due to the way fifties wiring works. But if you are certain that you would like as much top end clarity retained as possible then you can opt have them on if you like! But just wanted to give you a heads up!With or without Treble Bleed?

.01uF or .022uF neck position tone cap value?
Troubled by a dark sounding neck pickup? Well it's not totally un-common with Gibson type guitars or humbuckers in general so don't worry, you have some ways in which it can be improved. Although the standard spec harness will I'm sure help the pickup breathe and is ultimately the most popular spec choice, I now also with the choice of a .01uF value cap in the neck position instead to help clear up a darker sounding neck pickup. 
This is very much personal choice and/or how you are finding the balance between the neck and bridge pickup currently.  The main thing to consider is whether you feel your neck pickup is too dark/muddy compared to the bridge pickup. If it is and you want to try and help brighten it up a little, then a .01uF value cap in that position may be useful to you. If you like how your neck pickup sounds, then stick with a .022uF! It's the most popular choice and the 'go-to' cap value for most P90s and Humbuckers generally.

Righty or Southpaw, the choice is there to suit however your play!
Alongside the usual right handed replacement wiring harnesses, I also make these in left handed orientation. After a lot of research and customer orders over the years it seems 99.9% of Lefty players are used to using guitars with traditional RH taper pots. This is mainly because many guitar manufacturers simply fitted RH taper pots in LH taper guitars. But some LH players do of course prefer using LH taper pots, whatever your preference as a Left handed Strat player, I offer the spec to suit.

- CTS '450' Series +/-10% Tolerance short shaft pots - 500k, split shaft pots as standard on 335 kits. 
- For LH Taper kits - CTS Left Handed Audio taper 500k split shaft pots.
- .022uF 'Yellow Mustard' type tone capacitor  (If you'd prefer a different value capacitor, do please get in touch and I'd be more than happy to help, but as standard all of my kits come with .022uF value)
- Now also with the choice of .01uF value cap in the neck position to help clear up a darker sounding neck pickup.

- Switchcraft 3 way short frame toggle switch.
