Hello fellow modders! It’s time now to explore the third and final version of our master wiring schemes for the venerable Gibson Les Paul. So far, we’ve covered master volume plus master tone (“Les Paul Master Wiring #1”) and master tone plus two volumes (“Les Paul Master Wiring #2”). In this third version, the volume pot is the master and it will be supported by two individual tone controls. Although we call it a “Les Paul” master wiring, you can apply this mod to virtually any guitar with a similar dual-pickup, four-potentiometer configuration, such as an ES-335 or SG. And with a little ingenuity you can adapt it to any guitar with two pickups. For example, you can swap out the Gibson 3-way pickup selector toggle switch for a Fender-style pickup selector switch, which means you could use this wiring on a Telecaster.
He loves a rich, woody tone with nice overtones, so a certain cap from Roederstein is his standard. But he also wanted a warm, woolly tone as well as a slightly mid-scooped one, so we installed a rotary switch with his beloved Roederstein cap for the standard sound, a NOS paper-in-oil cap for the warm tone, and a standard “orange drop” cap for a slightly scooped sound. All three caps were 0.033 µF. The original Varitone design. The original Gibson Varitone design used an inductor to create a series of notch filters together with the capacitors. Personally, I think adding the inductor is not the best choice. The design may have worked in the ’50s, but today most of us are looking for different tones. (Joe described the tone of the original design in his article.)
The first things we need to do are check the compressor electrically and make sure it is safe to start; after making sure the compressor is safe to start, we need to reconnect it and see if it will start — the start assist (PTC) device may be defective; and when and if the compressor starts, we need to give the system a thorough check up to see why the technician was even doing what he was doing to cause him to disconnect the compressor,” Bob replied. “How can we make sure the compressor is safe to start?” Tim asked. “We want to make sure that it is safe to apply power to the terminals, Bob said. ”Use the Ohmmeter set on RX10K (10,000 Ohms). Second, fasten one lead to a good ground, scrape any scale or paint off the suction line, for example, and firmly hold the lead to the bare spot. Then, touch the other lead to one of the compressor terminals and record any reading. There should not be a reading. If there is a reading, the compressor has a ground circuit in the compressor. A circuit from the motor windings to ground. ”To illustrate how your meter works, you should be able to read a slight reading through your body if you hold one lead in each hand,” Bob continued. ”
Porter said he first started selling to local Oklahoma dealers ”who liked it and came back for more.” Then local distributors wanted to be involved; they now stock his products. A larger southern utility company, Georgia Power Supply, got word of his product and invited him to make a presentation at an open house in Atlanta. ”Those dealers present who were opposed to heat pumps now recognize it as a good thing,” Porter said. ”Georgia is one of our best markets.”
