D'AddarioScreeching Halt Acoustic Guitar Soundhole Cover - Acoustic Guitar Accessories - Eliminates Feedback

I bought this to try to control the howling feedback I was getting when putting my acoustic guitar through my new Blackstar amp. The feedback was making the guitar almost unuseable, so I thought I'd try this. I'm glad to say that it's quite effective. Some reviews say it doesn't mute the guitar, but it isn't meant to. It has definitely improved the guitar's useability, I can use it at a sensible volume with no problem. I used it for a gig with the guitar going directly into the desk and it was excellent, no feedback at all. It's a perfect fit in my Gibson J100, my friend uses one on a Takamine, so it seems fairly versatile. I'm more impressed than I expected to be with this cheap little gadget, it does pretty much what it says on the tin, and all for the price of a chip supper!

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.

Good quality product. Perfect snug fit, so won't be coming loose and causing problems during playing. Time to add the blues overdrive 👌

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.

Well impressed ! I live in a semi detached and didn’t want to annoy the neighbours with my heavy strumming. This is perfect! Reduces the noise but still sounds perfect. Also a perfect fit for the GS mini ! Would recommend

Very effective at doing what it does. A little awkward at fitting but, once on board, a handy little addition to making life better on stage with others kit around and sensitive amps.

It solves the problem of feedback with acoustic guitars.
