I've used a couple of KiOgon's wiring kits, and they are top quality components which are well put together, and easy to fit to your bass.
If you're thinking of getting a wiring kit for your bass - you won't do better and have an easier job of fitting than one of John's looms
Buy in complete and utter confidence folks

Have a good Christmas John, Nadolig Llawen from Wales :)

Hi John,

I'd like to upgrade the electronics on my main touring bass, a MIM Fender Jazz. I have always kept all volume & tone control pots wide open when playing live or in the studio and adjusted the tone, mid scoops etc on my amplifier or rack EQ... So, as my pots are basically redundant, would it be possible to bypass them and wire directly to the output jack from the pickups? If feasible, I'd like to pay you to wire up a a suitable configuration for me, pickups + output jack (1 x Jazz setup for touring bass + 1 x P-Bass setup for rehearsal bass) and I will fit & ground. Your work looks far better than I'd be capable of, its been years since I've done any serious soldering...

I recently bought a stacked pot set for my Jazz Bass from John and am a repeat customer of his. 

As always the quality is faultless and even a buffoon like me was able to install it without setting the house on fire using his very clear, easy to understand instructions.

Hi John,  I’d like to fit your VBT kit to my Lakland Bob Glaub (basically a P. Bass with jazz bass bridge pickup. The controls are positioned a bit wider apart compared to a jazz bass. Could you provide a kit with suitable spacing, bearing in mind that the jack socket is edge mounted, a la telecaster style? Cheers, Dave B.
