We proudly introduce our custom ‘Radioshop Telecaster Wiring Mod’ for your enjoyment in pre-wired harness form. We love the 3 main sounds that a Tele offers but have always felt that a little more could be teased out of the setup with a bit of simple modding. On the neck pickup and feel you just want a tiny bit of the bridge pickup mixed in to liven things up? Or maybe the bridge is just a little too much for you at times and could do with a little taming? A lot of us guitarists spend most of our time in the Middle position with our Teles just wishing for one simple thing … a bit more control over the volume of each pickup. With only space for two knobs on a Tele control plate, the options for modding are fairly limited but we feel we’ve hit upon something which solves the problem nicely. The ‘Radioshop Telecaster Wiring Mod’ gives you a new world of sonic possibilities.

Keeping the normal array of three way selector switch and master tone knob, we’ve swapped out the traditional tone knob for a dual concentric pot which gives you a new level of control over the sounds available. The upper knob controls the master tone as it would in a standard Telecaster wiring setup, whilst the lower, wider knob acts as a blender pot to blend in the bridge or neck pickup when not normally in action. This control is via a no load modification so when on 10, the knob does absolutely nothing and the pot is removed from the tone circuit. When dialling down from 10, the blend control comes into play giving a new tonal palette to play with. In the neck position, dialling down adds as much of the bridge pickup as is desired to the neck sound and when in the bridge position, dialling the knob down adds the neck pickup to the overall sound. Dial all the way down to Zero and you have the same sound (in all three positions) as the traditional middle sound so the mod is utterly pointless at this setting! The real magic is in the mid to upper reaches of the control. We can now subtly add the bridge to the neck sound and vice versa. Our personal favourite is the neck position with a little bit of the bridge added – a great sound for rhythm playing! The bridge pickup too with just a little of the neck added is a really useful sound – it just seems to take our Tele up a few notches in the Twang stakes. Of course, the amount you blend in by is up to you and there’s a lot of fun to be had just playing around!

Delivery By default all of our pickups are shipped with Royal Mail who we find to be excellent both within the UK and Internationally. Their rates enable us to offer prices that are very reasonable for our customers and the timeframe is great for the vast majority of countries. We find that, once despatched, Royal Mail tend to take 1 working day within the UK, 2/3 working days within the EU, 4/5 working days to North America and Worldwide. These are guidelines and of course some countries differ and the level of ‘officiousness’ in customs departments differs massively worldwide. If ordering from a country which is notorious for taking a while to process imported goods (we can think of a few!) please build this into your expectation on the timeframe after despatch. How long will it take to make? As a small pickup maker handmaking within an extremely busy workshop we expect to complete all pickups sets within 16-20 working days (Relic’ed orders 5 days longer). We sometimes work quicker than those timeframes and we’ll always endeavour to finish your pickups as quick as we are able to of course. We can sometimes process a rush order if you have an upcoming, important concert or perhaps if you are buying for a relative’s birthday etc - feel free to message and we’ll always see what we can do.
