If you are looking for a EMG active pickup wiring 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 diagram involves the installation of battery-powered active pickups (typically 9V or 18V for a wider dynamic range).19 Characterized by almost no hum and high immunity to high-frequency interference.19
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
The equipment includes two active pickups (e.g. EMG 81/85), two logarithmic or linear potentiometers, an integrated active capacitor, a 1/4″ stereo output jack, and a 9V battery clip.3 The red wires of the pickups and the red wire of the battery clip are inserted into an isolated V+ power terminal block.19 On the stereo jack 19:
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.
