What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 01
Sized to a specific soundhole diameter. Measure your soundhole first — the wrong size won't seat properly.
Detail 02
A middle setting between airflow and blocking. Cuts feedback while letting more of the guitar's voice through than a full block.
Detail 03
Wood instead of rubber or plastic, so it damps the air column without adding the muffled quality of a solid plug.
Detail 04
Blends against most spruce and mahogany tops rather than sitting in the soundhole as a black disc.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
Measure the soundhole across its widest point with a ruler. Dreadnought soundholes are commonly near 4 inches, but confirm on your own instrument.
It reduces the low-frequency resonance that causes feedback. Expect less boom and a tighter amplified sound.
Yes, but your unplugged volume and bass response will be reduced. Most players remove it for acoustic playing.
It seats in the soundhole rather than attaching to the top. Keep the fit snug but not forced against the soundhole edges.
