Great product, Makes a lot of difference in sound and play ability. To say nothing of staying in tune. I put one on a Ovation Legend made in 1972. The guitar always sounded good but was a little tough to play. This made a world of difference. It is now amazing. I have a friend who can't keep his hands off of it. He likes it better than his Rainsong.
I bought a Gold Tone OB 150 Masterclone banjo that is equipped with a Zero Glide nut. This nut is amazing. YES it will help with tone. No more string binding with Zero Glide. Ever notice on a new instrument how when you are tuning up and on occasion you hear a sound like a string is catching in the slot You will not have that issue with Zero Glide. Once you actually play an instrument with a Zero Glide nut you will notice some differences. You may want to outfit all of your stringed instruments to Zero Glide. No need for slot files to set the action at the nut side of the neck. No more smoothing out string slots with high dollar files that snap really easy. No more using graphite or grease on the nut. Zero Glide takes care of that. Might be the first healthy choice for a nut for your instrument. Get one and install it. You will love it.
I was having a very hard time finding the right nut replacement for my mandolin. Finally found this one at StewMac. Have never used the zero glide before, but this one works great. Had a good deal of sanding to do for a perfect fit, but it works great and sound is super on my mando. Thanks guys!!
I have 3 instruments with a Zero Glide nut that I play regularly on shows and in jam sessions. My Gold Tone OB 150 has one as standard equipment from Gold Tone. Next is my Martin D custom Acoustic and next is my Washburn M3SWK F body mandolin. I did the install on those last 2 instruments. YES, you WILL have to do some fitting. Follow the instructions to the letter on this. YES, you may find it to be a pain but the gain is more than worth it. Once the Zero Glide is installed and once you start playing a few tunes, you will wonder why you have not installed a Zero Glide nut a lot sooner.
No more string binding issues, no more graphite in the slots or any grease either. You don't need that stuff anymore. No need for nut slot files either with a Zero Glide unless you get one un-slotted. You will still have to fit the Zero Glide nut so you can make it a part of your instrument. No getting around that. It is all part of the fun so enjoy the pain and take your time with the fitting. Once that is done, the action at the first fret will be perfect. Your tone will be better. You will get some sustain you haven't had before. The Zero Glide nut should be the ONLY nut to go on your instruments. I like what it does for playability and tone.
