Compensated nut insert
It's solved intonation issues on my fender acoustic. Open chords ring out. I tune to C# standard and it slightly raised the action and stopped string buzz. Great product!
Yes, this does work!
My Washburn D10SDL acoustic guitar now sounds great! Open G, D, E, C and all other chords and notes (even with capo) finally play in tune. Sure, 16 bucks for a tiny piece of plastic sounds steep but it's well worth it! Precision cut hard material did not deaden my strings. No regrets. Fast shipping.
Worked for me, big improvement.
The strings need to make good contact with the SOS extension. That means you may have to file the string groves in the nut. You will need nuts files to do it. Just for the record, I'm writing this review as I'm ordering two more.
Soft material kills sustain on 1st & 2nd strings
No noticeable improvement in intonation on Taylor 814ce. Material is too soft and kills sustain on 1st & 2nd strings --Admin-- The SOS will make 1st position chords sound more in tune. Some will barely notice a difference while others will hear a big improvement. The SOS are made of a bakelite material and that is not a soft material. It sounds like the SOS doesn't have good contact with the 1st and 2nd string if it's killing sustain. You can use the included shims or deepen the nut slot to increase the strings contact with the SOS.
Even though the saddle is adjustable, this product improves intonation by insuring that the open strings are in tune with the rest of the notes on the guitar. I am having a guitar custom made, and my guitar maker intones at both the bridge and nut.
