D'Addario Accessories Screeching Halt Acoustic Guitar Soundhole Cover - Acoustic Guitar Accessories - Eliminates Feedback,Black

I bought this for an ovation electric/acoustic, to use effects and hear it only through the amp, plug the acoustic and turn it into an electric...ish, have fun.It has a nice tight fit. pops out easily enough, sturdy, heavy rubber. D'Addario have never let me down. I'm not a fanboy, but this was under $6 and I also have a Martin and I'm interested to see if I can put it into "practice mode" past midnight.I literally just used it for the first time for 5 minutes, on a blues DeVille of all things (it was "right there"). I know it's to cut feedback, but for my intentions, it works well. and yeah, no feedback, but ovations use a piezo, so no magnetic field.I'm thinking of leaving it in the ovation and getting another for the martin. for less than $6, this is competing with all the other knock offs, and has a name I've come to personally trust, and yeah: lots of guitar accessories are tony plastic pieces of whatever, but there's a way to do it right, and I've never bought a new tool after buying one built by D'Addario. Then again, i've never tried another version, and I cannot stress this enough: I bought mine for less than $6.Ok, I've convinced myself to buy another for the Martin. My dudes, they had D' clip tuners for like $6 once and I bought one for each case. The batteries are probably dead now because i use a poly3. but it's under $6!!!

I’ve been a professional musician for 30+ yrs, and I’ve used this brand many times over the years. It works perfectly and does what it’s suppposed to do. Just make sure it fits! This will depend on your guitar. The actual dimension of this plug is 4.040”, so, roughly 4 and 1/32”. My Martin’s sound-hole is 3.990”, and this particular plug will not fit, it’s too tight. I could probably force it in, but I’m not doing that. No worries, I have other guitars that it’ll fit. But for this particular Martin, I found (on Amazon) a sound hole cover that is 10cm which equals 3.937”, and it’s a perfect fit. No forcing. So my advice is to try this 4” plug first, it’ll probably fit. But if it seems too tight, don’t force it. Search on Amazon for the 10cm plug and you’ll be happy.

This fixed feedback issues with my Taylor 314ce. It was a little tight but not difficult to install. Stays in place.But it absolutely does change the sound of the guitar and make it a bit more dull. It's just the nature of things, all brands/models of feedback eliminators do that.

I'm being very generous with this review.I own a fender sonoran SCE acoustic electric in seafoam green. However, if you know this guitar. The fret board actually hangs over the soundhole just a tiny bit. Making it an excessively tight fit. To the point it almost worries me.With that being said. I put it in my other fender acoustic and it fit fine. But It doesnt serve my purpose because the one it fits is far from what i prefer to use for recording. I could probably snip it and trim it. But it just sounds like a pain to make it look good.So. The verdict. And my honest opinion.This is a solid little sound hole plug. Rubber type material. USA made and by a good brand. I will keep it. Throw it in the bin. Who knows when youll need something like this. If you have a full circular soundhole. Its definately worth a try.

It was tough to get it in place on my Guild OM-240CE but once I did, it worked as it should.

It doesn't fit either of two Martins, nor my Epiphone. It's closer on the epiphone but just can't be forced in safely. All these guitars bought in last fifteen years. So I returned it.This leads me to believe it will fail to fit a good number of guitars. If you don't want to deal with returns I'd recommend measuring your guitar and reaching out for actual dimensions before ordering.

Very durable and solid hunk of rubber. Fits perfect in my Taylor 214. Makes a big difference for fighting against feedback and can also be used to quiet the guitar in a small room

Highly recommend for acoustic/electric guitarists who perform with full-bands! Works as advertised, especially when performing on stage surrounded by mid-low and low frequencies that can cause feedback. I perform with an Orangewood Echo Live with Fishman Flex-EQ preamp, and it does not affect sound quality of the guitar when performing live. It is easy to remove when not needed, and stores perfectly in the storage compartment of my guitar case.
