Screeching Halt Acoustic Guitar Soundhole Cover - Acoustic Guitar Accessories - Eliminates Feedback

Good quality item, fits my Martin guitar perfectly and reduces feedback when plugged in to the PA.

Does as expected, fair price (I would rather pay this for a trusted brand instead of an unknown brand for cheaper). Feels robust and secure when in use but flexes enough to not damage guitar

It does it's job, very snug and secure fit with a decent finish. Sadly, mine came packaged stapled to a cardboard backing, leaving a hole in each side of the front of the item. PW did previously ship the item in a clear bag, with the cardboard holding the bag closed at the top, but they have changed this packaging for some reason. In any case, the product does a great job of reducing feedback, and reducing the volume for bedroom practice etc.

My guitar has a slightly smaller than standard sound hole (which is about 100 mm) - so this was too big to fit without risking damage to the guitar. The solution is the file down the edge of the cover - which is quite thick so you get plenty of adjustment room. I don't have a file so I used sandpaper which did the job. Took about an hour to get a good fit. Now fits perfectly and completely eliminates feedback when playing at gigs. Nice quality and rubber is quite soft so it will not damage the finish on your guitar.

Works well.

I have a Fender 60CE and strangely it doesn't fit my guitar. I did my best to press it as hard as I could but still... So, because it was really marginal I had to trim it a bit, but I didn't have the skill to do it perfectly so it works but not as good as I would like to. I have no idea why it fits the other peoples' holes (pun not intended) and although it might have not worked for me but seems of good quality. Btw, I had seen that it was advertised 10cm, but as I said the discrepancy was very marginal, so I dont know if my guitar hole is smaller or this thing is bigger.

The product is excellent and fits the diameter of the opening on the guitar which is larger than usual. Exactly what I was looking for.

A nice solid piece of rubber which is a perfect tight fit in the soundhole. only minor quibble is that I had to detune the guitar in order to slip it under the strings. I don't have a particularly low action so it was slightly (only slightly) annoying. guess I'll just have to keep one guitar with it permanently in place. However one big plus is that it makes the guitar sound more mellow and fuller even when unamplified. Well worth the money.

Perfetto, si inserisce con grande precisione nel foro della chitarra, si avverte che il materiale è di alta qualità.

Not suitable for acoustic guitar. You blocking the glory hall but strings still making sound. Rubbish

Gutted that they didn't mention the size

まあまあ音が静かになるかなぁ〜といったところです！

Produto excelente!
