2 pickups with master volume and master tone: diagram
If you are looking for a wiring 2 pickup master volume Clear and practical, you're in the right place. Here you'll find the diagram, explanations of the connections, and tips for avoiding common mistakes.
Introduction
This universal diagram controls two passive pickups by blending them via a 3-way selector and adjusting them with a single global volume control and a single global tone control.38
Wiring diagram
Download the SVG diagram and use it as a reference while soldering. The star ground is the central point: all ground wires must converge there.
How to read the diagram
It features two passive pickups, a logarithmic master volume potentiometer, a logarithmic or linear master tone potentiometer, a capacitor, and a 3-way selector (toggle or lever).3 The hot conductors of each pickup connect to the input terminals of the 3-way switch.9 The common output of the selector connects to Terminal 1 of the Volume potentiometer.4 Terminal 2 (center) of the Volume goes to the tip of the jack. The Master Tone is wired by connecting its Terminal 1 to Terminal 1 of the Volume 33, while the capacitor connects Terminal 2 of the Tone to the casing of the tone potentiometer.33
Practical steps
- Prepare the components and check the values of potentiometers and capacitors.
- I soldered the hot wires following the diagram, avoiding unnecessary jumpers.
- Connect all the masses to the indicated star point.
- Check the continuity between the bridge, jack and potentiometer covers with a multimeter.
- Test the instrument and fix any buzzing.
Tips to avoid buzzing
Avoid the ground loopIf the potentiometers are on a common metal shield, do not solder ground wires between their caps. Use an open "C" or "horseshoe" path and connect each ground to the star center. For more information on modifications, see also guitar modification guide.
FAQ
Which potentiometers should I use?
It depends on the pickup: single-coil generally 250k, humbucker 500k, active 25k.
Can I use a different capacitor?
Yes, but the value changes the cutoff frequency of the tone. Higher = darker sound.
