![]() Don’t spray any cleaners, magic in-house recipes, or other funny things inside a switch as part of regular servicing. This keeps all the contacts clean and will guarantee years of trouble-free operation. The only reliable way to protect and pamper your switches-closed or open-is to use them often. This area is already protected against dust and moisture, and I’ve never seen a rusty or dusty open switch on a Tele control plate. The 3-way switch is mounted underneath the metal control plate and is resting in the more-or-less isolated electronic compartment. Okay, this may be true, but is it an important factor? Look at your Telecaster. One argument in favor of closed switches is they offer protection against dust, humidity, and moisture. I can only say I’ve never had a problem with an open switch, but I’ve seen and serviced countless guitars with faulty and noisy closed switches. What’s the best switch design for guitar? Well, as you can imagine, it’s a never-ending debate. These sport an open PCB based construction, as shown in Fig. Some switches, such as the Eyb or the Schaller units, are mixtures of these two main types. 2 shows a budget closed 3-way switch with a completely different layout. 1 shows the classic CRL 3-way switch from both sides.īy comparison, Fig. For example, you can easily clean the contacts and rework the tension of the spring if necessary. It’s so much easier to understand what’s happening in a given position when you can view which lugs are connected.Īnother benefit of this construction is that it is serviceable if there’s a problem. The open switches-CRL, Stew-Mac, and OakGrigsby-offer robust construction and the benefit of letting you see what the switch is doing when you move the lever. You can divide these pickup selector switches into two main groups: closed and open. The only reliable way to protect and pamper your switches-closed or open-is to use them often.ĭesign basics. And Seymour Duncan and DiMarzio use it as their standard, so we’re in good company. Here’s why I’ve decided to use the CRL switch: It’s the most common switch in the guitar world, and you’ll see it configured in many wiring diagrams. Because of these physical disparities, we need to settle on a standard before we start our 3-way switch odyssey. These switches I’ve mentioned are all different, yet they do the same thing. Though production stopped some months ago and currently offers the CRL 3-way switches, I’m sure some Stew-Mac units are still available as remaining stock at a few guitar shops. Stewart-MacDonald also sold some switches with a special layout. As you probably know, many companies produce guitar switches, and popular brands include Central Research Laboratories (CRL), OakGrigsby (now owned by Electroswitch), Neutrik, Schaller, and Eyb. Please put on your white lab coat and pull out your dissecting case. We’ll start with design basics and then learn how to install a new switch, discuss how its individual lugs work, and also figure out ways to apply this info to other switches and guitars. I’m going to split this switch tutorial into three installments. Ultimately, this information will help you develop your own mods and comprehend many different wiring schemes, even for other types of guitars. Many future mods depend on this knowledge, and acquiring it isn’t as painful as you might think. But believe me, it’s important to understand the basics of this switch. for some of you this topic will be as entertaining as a case of athlete’s foot. Now we’re ready to explore the 3-way Telecaster pickup selector switch. We’ve even done our homework by studying different eras of Fender’s stock Tele wiring schemes. So far, we’ve learned how to prepare the guitar’s standard 2-conductor single-coils for hot-rodding and taken steps to reduce feedback. We’re making headway in our epic Tele-modding journey. Some switches, like this Schaller unit, sport an open PCB-based construction.
