Most guitar players don’t actually know which tone cap they want.

Not because they don’t care —
but because finding out the traditional way is a pain.

To compare caps properly, you’d have to solder one in, restring, play, take the guitar apart, then do it all again for the next cap. By the time you test another one, the previous sound is already gone from memory.

Real A/B testing is almost impossible — so most players just guess.

The BTone Tone Cap Tester Fixes That

The BTone Tone Cap Tester lets you hear what different capacitors actually do without installing anything.

• Plug your guitar into the tester
• Plug the tester into your amp
• Clip any capacitor to the alligator clips
• Play and roll the knob

You can swap caps in seconds.
No soldering. No disassembly. No restringing.

Same guitar, same amp, same strings — only the cap changes.

Choose the Right Pot, Hear Real Results

The Tone Cap Tester is available with:

• 250k pot – standard for single-coil guitars
• 500k pot – common for humbuckers

Choose the pot that matches your guitar so what you hear translates directly when you install the cap.

Commit With Confidence

Once you find the cap that sounds right to your ears, then you install it — knowing exactly what it does.

No guessing.
No wasted time.
No regret.

Dial in your tone before you commit.
