A soundhole cover is a plug that sits in the opening of an acoustic guitar. Makers describe them as a way to cut feedback when the guitar is amplified, and some list them for quieter practice. The size of the opening decides what fits, so measure it before you order.
The six covers below span soft rubber plugs from D’Addario and Ernie Ball, a flexible tapered cover, a four-piece silicone set and a wood and sponge model. Sizes, materials and contents come from each listing page. We have not used these products ourselves, and performance claims are the makers’ own.

The 6 Best Soundhole Covers
1. D’Addario Screeching Halt
A soft rubber soundhole plug that the maker says fits most standard 4 inch soundholes and installs and removes without tools. The listing says it needs no modification to the instrument and is meant to cut feedback and raise stage volume. Weight is listed as 0.07 kg.
Suits: a standard 4 inch hole. Strengths: a well-known maker and a rubber insert. Weaknesses: the listing has a stray battery-power field. Skip it if your hole is 3-3/8 inch.

2. Ernie Ball P09618 (4 inch)

Suits: larger 4 inch openings. Strengths: clear sizing advice. Weaknesses: only one size per listing. Skip it if you need a wood look.

3. Ernie Ball P09630 (3-3/8 inch)
The smaller sibling of the 4 inch model, made of the same non-abrasive rubber and sized for 3-3/8 inch soundholes. The maker says it fights unwanted feedback and noise and fits without tools. Listed weight is 2.46 ounces.
Suits: smaller soundholes. Strengths: the same rubber as the larger cover. Weaknesses: will not fit a 4 inch hole. Skip it if your guitar has a standard dreadnought opening.

4. Alucinico Feedback Suppressor
A black cover with a flexible, tapered contour meant to adapt to most 4 inch soundholes without adjustment. The listing says it works with most pickup systems, is safe for finishes and inlays, and lets you play louder without feedback. Weight is 2.39 ounces.
Suits: a pickup-equipped guitar. Strengths: a tapered fit. Weaknesses: a lesser-known brand. Skip it if you want a name-brand rubber plug.
5. Piutouyar 4 Pack
A set of four covers: two for 38/39 inch guitars and two for 40/41 inch guitars. One bullet says they are silica gel and another says they mute sound for quieter practice. The same bullets say they suit electric, folk and classical guitars, which is broader than the acoustic wording elsewhere, so check the fit.
Suits: owners of two guitar sizes. Strengths: four pieces in two sizes. Weaknesses: loose listing wording. Skip it if you need only one cover.

6. Bnineteenteam Wooden Cover
A wood and sponge cover, 4.13 inches across and 0.35 inch thick, listed for 41 inch guitars. The maker describes the sponge as soft and elastic, quotes a weight of roughly 31 to 34 grams, and says it needs no change to the instrument. The title says classic guitar while the bullets say acoustic.
Suits: a wood-look finish. Strengths: a sponge layer and light weight. Weaknesses: a mixed title and bullet wording. Skip it if your hole is smaller than 4 inches.
Fitting Notes
- Measure the soundhole across before choosing a size.
- Press the cover in gently and check it sits flat.
- Remove the cover when you want the guitar’s open sound.
- Wipe the cover and the rim of the hole with a dry cloth now and then.
Mistakes to Avoid
- Ordering without measuring the opening.
