If you play a dual-humbucker guitar with individual volume controls—like our Artist 58 Series, AP1, AG1, or AG100—you might have run into a quick quirk that leaves a few players scratching their heads.
Flick your pickup selector switch to the middle position, roll just one of the volume knobs down to zero, and suddenly… total silence. The whole guitar cuts out, even though the other volume knob is still sitting on 10!
First off: don't worry, your guitar isn't faulty! This is completely normal behaviour for standard two-humbucker wiring. Here is a quick breakdown of what’s actually going on under the hood.
When your selector switch is set to the middle position, both your neck and bridge pickups send their signals down the exact same path toward your output jack.
Because of this setup, your volume knobs don't just act as simple on/off switches—they turn into a blend control for your tone.
You can roll one knob back a bit to dial in the perfect balance for your sound:
Inside your guitar, each volume control (a potentiometer, or "pot") acts like a traffic controller. When you turn the volume up, it sends your signal out to your amp. When you roll it down, it diverts that signal off to "ground."
When you drop a volume control all the way to 0, you open up a direct, path-of-least-resistance straight to ground.
Since both pickups are sharing the exact same output path while you're in the middle switch position, that open ground path pulls the signal from both pickups down with it. That’s why the whole guitar cuts out instead of just one pickup!
This design is called dependent (or standard) wiring, and it’s been the classic factory setup on dual-pot guitars for decades. Guitar builders love it because it keeps your high-end clarity nice and crisp when you back your volume off slightly.
Some players prefer to rewire their guitars for "independent wiring," which lets you turn one pickup completely off in the middle position without killing the other. However, modifying it this way can take away a little bit of your top-end sparkle when rolling back the volume.
If your guitar operates as expected when switching to just the neck or just the bridge pickup on their own, your controls are working 100% as intended.
Instead of turning a volume knob to zero to kill a pickup in the middle position, simply use your pickup selector toggle to switch between them. Use those dual volume knobs for fine-tuning your blend, finding unique tonal sweet spots, and shaping your overall sound!
