Stylish and functional

I used these to replace some worn-out shiny knobs on my custom pedalboard. The matte black finish looks professional and the grip is excellent for quick adjustments.

Perfect replacement for my old pedals

These knobs fit perfectly on my Boss and MXR pedals. The duckbill slot makes it very easy to see the setting at a glance during a gig. Highly recommended for anyone needing a quick fix.

Good quality, tight fit

The plastic feels sturdy and not cheap. They were a bit tight to push on initially, but that ensures they won't fall off easily. The white indicator line is bright and clear.

Solid little knobs

They do the job well. The indicator line is helpful for remembering settings. One knob was slightly loose on my shaft, but the others were perfect. Overall happy with the purchase.

Exactly what I needed

Lost a knob on my volume pedal and these matched the original perfectly. The slotted design is classic and functional. Great value for a 5-pack.

Great for DIY projects

Building a few budget pedals and these knobs finished the look nicely. They fit standard 6mm pots without any modification. Will buy again when I build more.

5 FAQ

Q: Can I use these for high-power amplifier main volume controls?

A: These are best suited for low-voltage effect pedals and pre-amp controls. For high-power main volume amps with larger shafts or heat concerns, we recommend checking specific heavy-duty replacements.

Q: Will these fit on potentiometers with a smooth round shaft?

A: No, these knobs are designed specifically for split shaft (slotted) potentiometers, typically 6mm in diameter. They may not stay secure on smooth round shafts without adhesive.

Q: What is the exact outer diameter of the knob?

A: The outer diameter is approximately 18mm (0.71 inches), which is a standard size for most guitar effect pedals and small amplifier controls.

Q: How many knobs come in one package?

A: Each package contains exactly 5 pieces of the Duckbill Slotted Knob, allowing you to replace multiple controls or keep spares on hand.

Q: Does the white indicator line glow in the dark?

A: No, the white indicator line is painted for high contrast visibility under stage lights or room lighting, but it does not have phosphorescent or glow-in-the-dark properties.
