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

fits a Yamaha acoustic perfectly and works as advertised. great price too.

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!!!

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’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.

I was skeptical but thought I'd try this five dollar fix to tame persistent feedback on my Taylor/Fishman combo. This rubber disc definitely lives up to other positive reviews here. When facing the amp two feet away, I am able to get higher volumes without any discernable feedback. I can only imagine what this will do when the amp is 5-10 feet away in a gig situation. Great product.

The item itself fits a bit too loose on my guitar. It still gets the job done tho... It seems to be quite durable however.

I was seriously thinking about trading in my PRS Angelus SE because I couldn't control the feedback while playing amplified through my Traynor AM 100 acoustic amp. As a last-ditch effort, I ordered one of these sound hole covers. Not only is the feedback problem (at considerably high volume solved, I found that playing single string lines and arpeggios were crystal clear and far better articulated than playing the instrument in open sound hole mode.

My sound man now loves me. Took the screach out of my K&K pickups in my jumbo acoustic. I only use this for stages with lots of lights and messy frequencies.

Ajusta perfecto. Buen material

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

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

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！
