Single best upgrade I ve ever done

Jan 11, 2025
Replaced a stock plastic nut on my Squier Jaguar short scale bass with a zero glide today. Hand down the best upgrade I ve done to that or any instrument since I ve started playing. Action is now perfect intonation is spot on tuning is even better/easier as there is less friction to deal with. My initial reasoning for this upgrade was to minimize any nut work needed when changing string gauges now I just have to set intonation and tuning and it s good to go I didn t expect the immense open string clarity change nor did I expect that this bass could get any more sustain out of it but I stand corrected I ll be upgrading every bass and guitar I own to a zero glide now If you re on the fence just go for it - you won t be disappointed

Zero Glide ZS-17F

Jul 7, 2017

I purchased a '97 Squier Vista MusicMaster Bass locally. The stock plastic nut needed replacing or filing. I had already pulled the nut off of the MusicMaster and had all measurements noted before replacing the stock nut temporarily. The Zero Glide ZS-17F Precision Bass Precision Bass model specs matched up with the MusicMaster specs. Cool. After my Zero Glide arrived I pulled the stock nut and lightly sanded the nut slot on the fretboard with fine sandpaper to remove any debris or adhesive residue used on the stock nut. Next I slid the Zero Glide nut onto the fretboard. Nice snug fit. The width of the Zero Glide was perfect. My next step was to make sure that the top / flat surface of the nut was flush with the fretboard. This is crucial to allowing the fret to seat correctly on both the fretboard and the zero fret nut. On my MusicMaster this required a very thin shim under the Zero Glide nut. Once the nut was seated properly it was just a matter of selecting which of the fret sizes provided is required for the instrument. In my case this was the longest installation step time-wise. Once you have selected the proper fret, mark the fret and cut with the proper tool. Examine the cut end of the and correct any imperfections due to cutting on the tang of the fret by filing. A small bench top vise with padded jaws and high quality file makes this step a snap. Installation time in my case : - shimming me the nut, less than 10 minutes - selecting the correct fret size, 45 minutes - all filing on the fret ends and top corners of the nut, less than 15 minutes I'm very pleased with the results. The open string notes sound like fretted notes of course, and I was able to achieve noticeably lower action without fret buzz after a setup. I'm especially pleased with the improved note definition of the open E and A strings. I did not check the intonation with the stock nut on the 1st five or so frets before I installed the Zero Glide, but the intonation is fine on the lower frets. My order was processed and shipped promptly and Gold Tone customer service is excellent. Thanks for a great product !

Nice Banjo Upgrade

Apr 18, 2016

The bone nut was easy to install. I sanded the length and depth with a table sander. The instructions are complete and easy to follow. Four zero frets of different sizes are included in the banjo kit--you try the smallest and work your way up until you have no open string buzz. Use medium viscosity cyanoacrylate (available from Stewmac) so you have time to set the nut and fret properly. I'm pleased with the results, improved tone, and hammer-ons and pull-offs are more defined.

Good stuff The rest of the story 2

I just put the Zero Glide on my guitar. Very impressed. This is as close to perfect as I can get. I can bend all over the guitar and 95 of the time the notes come back to the original pitch....the few times they don t it s so minimal most people wouldn t notice it....I really believe that it s probably the tuners....they re decent low grade tuners. Nothing special. Amazing considering this is a 300.00 guitar. I checked the space between the 1st fret and the E and B strings fretted at the third fret...distance between 1st fret and bottom of string .....they looked like they were less than a thousandth and the guitar was not buzzing on an open string. The action is very low with extra thin strings on it. This made the guitar play even easier. I had the strings set at about 4 thousandths from the first fret while fretting at the third. This took them lower....especially on the first 5 frets. Good job on this I do wish they would have sent me a smaller fret.
