    May require some modification
    I bought this to reduce the sound of my classical guitar for midnight practice. I already have something under the strings that removes most of the high frequencies. This removes most of the low frequencies, balancing the overall, reduced sound pretty well.I had to trim some material off the edge of the item where it interfered with the fingerboard on my classical guitar — after that, it fit. I made it so that I would have to force it into position and this would hold it in place, because despite my measurements of the sound hole, the product was slightly to small for a snug fit. Also, the material is strange — a fairly hard, primitive rubber/plastic that smells strongly between tar and black licorice. The smell is almost too much. Not sure why they didn’t just use a soft silicone rubber that would flex more (and fit better) and not smell so bad.

    Not accurate sizing
    The size is not as advertised.

  5. Frankie miles

    Load of rubbish, doesn’t fit or stay in the sound hole. Binned it already

    As described, does the job, but heavy
    Got this to keep cat hair out of my guitar while on the stand. It does that just fine.Pros- snug fit on my Fender Dreadnought guitars (3.93″ and 3.95″ sound holes on the digital caliper). Almost too tight, but I’d rather that, than have it fall out.Doesn’t diminish tone very much.Cons- not hard to install, but go slowly,lest ye ruin the finish around sound hole.Adds significant weight to the guitar, so…. be ready for that.

    4” cover is smaller than 4” so falls out of sound hole. Waste of money, DO NOT BUY.

  8. Carole Evans

    It fit the acoustic I own and works great. Looks pro.. what else can you ask for.
    Works great..

  9. Shane

    Perfect Fit
    Perfect, 4″ standard sound hole size, I have a Art and Lutherie guitar.

    Might not fit your guitar
    This fit my Martin D28 but it is too loose for my Taylor
