Fret levelling: How low is too low?

I finished levelling frets on a mandolin last week, and was surprised that the frets with the worst divots worked down to .020" Had I known that I'd go that low, I might have replaced them, but it's hard to measure divot height, especially those caused by thin strings. I haven't seen much discussion on standards for fret height or guidelines to know at what point should I switch from levelling to replacement. What standards are peop…

I’ve found for most guitar players anything below .030” starts to get into refret territory. Might be different for mandolins though, I don’t work on many of those. I have a client that loves the fret…

Weird situation with PRS SE Angelus acoustic truss rod

I've got a PRS SE A50E acoustic in with complaints of high action. Checked the relief and it was sky high. Tried to flatten it, and it wouldn't go, so I started experimenting. When there's no string tension and the (single action) truss rod is slack, there's loads of relief. Tightening the truss rod works fine and the nut turns easily until the neck is flat, then resistance goes up but the neck won't go past dead flat. It behaves as…

With all that extra relief it's probably hard to tell, but is this a double action rod? As far as compressing into a back bow, it can be done if the untensioned relief isn't crazy. It dounds like you…

Any helpful tips with bar frets?

Hello, One of my commissions is coming down the pike and it's going to be my first time using bar frets. I could use a once over for any helpful tips if you have any. About the guitar: Aged HD-28 but mahogany back and sides. I think Martin called this a HD-28 M? Skipping the truss-rod and using two carbon fiber strips. My process for Frets: 1: I CNC my fingerboards to a 16" radius and for T-frets I use a .023" to cut slots with a mat…

Depending on the carbon fiber strips and the gauge of string, you're compression may be moot, or at the very least, a fairly subtle factor. I would do a lot of testing before you glue the neck on to t…

1964 jazz bass calamity

Any suggestions if this can be saved? It is a neck I received for free upon replacing it for a customer. The wood was missing and the rod is missing the adjusting nut. The truss rod had pushed the inlay out as well as the wood damage . I wasn't sure if it could be a structurally sound repair. I have no idea of the neck rigidity or action with strings. I wont be online because of a previous dr. appointment but I figured it would be a go…

The Elders are correct .It is a 1976 neck. I was presently working on a different neck , a 1965, so it was on my mind. Thanks to all for the suggestions. My initial instincts were what Doug had reco…

Buzzing following nut replacement

Hello, I replaced a nut with a tusq nut. Nut slot height is correct, neck relief is good, action is good. But I’m still getting buzzing on low E and A strings on frets 1-3 primarily. I checked the fret height on fret 1 and it is sitting lower in that area specifically .038 inches. Vs .040 inches for the rest of the frets. I’m thinking this is what’s causing the buzz. Is my thinking correct? Is there something I can do other than a fret lev…

GoBar deck adjustment

Hi folks, I thought you might be interested in this approach to having easy height adjustment for a GoBar deck. I learned this tip from my buddy, Don Parker. He lurks around here too from time to time. :) The basic idea is rather than having a booster platform on the base for use when gluing braces to plates you bring the roof down lower. There is a 3D printed spacer in black in the pics. I linked to a downloadable STL and 3MF of…

Just FYI, as far as I know, go bars have the same clamping strength no matter how much they are bent. If you want a different level of force, you need a heavier go bar. Or vice versa.

1917 Gibson U-type Harp Guitar

I’ve had a customer come to me wanting to electrify the guitar without any modifications to it. No drilling, routing etc. I did convince him an end pin jack would be the only mod I would make, and he was ok with that. After a little thought, I thought, a K&K with a microphone (K&K Mini Pro) might work, using the transducers on the six string side and the microphone on the ten string side. I have no doubt the transducers would work fine.…

Just a follow up, K&K is making a custom 3-4 transducer system for this. Vance at K&K was a pleasure to work with... thank you Vance!

Nut slot and action trouble

Hi everyone - I recently ran into trouble making new nut for one of my necks that needed to be trued and re-fretted. I roughed in the nut as usual and then, with the bass guitar fully assembled and strung up, I started cutting the slots to depth. I use the StewMac digital nut slot depth gauge and have had good results in the past. I marked the nut's lowest points (radiused) using the guitar nut scribe tool (first time using this!) and c…

That's actually not how that tool was intended to be used. That is essentially plotting a like to the top of the fret. With a bass, you would need much more than that. When James and I came up with th…
