Les Paul Truss Rod Spacer and Nut

I have a 2024 Les paul in fine shape. One thing i’m curious about is that the nut and truss rod spacer appear to have been modified but there are no finish marks in the cavity to suggest a repair. is this a normal factory install adjustment and have other folks here come across it in les pauls?

Intonation: Ive never seen this

I'm restoring an old parlor guitar. I have just discovered that it plays 20 cents sharp. Thats not in and of itself a mystery, usually. This guitar however has exactly the same distance from the nut to the 12th fret, and from the 12th fret to the "saddle" which is now a small shim under the two E strings both are 12 3/32"...with room in front of the bridge pins to finesse the location of the saddle slot, which I have not routed yet) I s…

String radius at bridge & at 14th fret are totally different??

Hi there! Working on a Squire Vintage Modified Jag. relevelled and crowned the frets. Lovely job. Set the relief and action to factory spec. So far so good. With a capo on the first fret, I set the string radius at the saddles to 9.5" using an under-string radius gauge, everything lined up nicely... ...but when I measured the action of all the strings along the 14th fret using my digital nut slotting gauge (expecting a unifo…

If you adjusted your truss rod and action to factory spec, then you adjusted the radius at the bridge, you changed the string action height. I know some will set the action on both e strings and then…

The Neverending Fret Buzz

Hi everyone, Every once in a while, I come across a bass that simply refuses to stop buzzing. Right now, I’m working on a bass (I won't name the brand, but it’s in the €2,500 range) that has a slight fretboard hump near the neck pocket. I figured that was the culprit, so I performed a fret level under string tension. The frets are now perfectly level... yet, it continues to buzz across the entire fretboard, even with fairly high a…

After further testing on a bass with the same issue, I discovered that in some basses, the neck has a specific resonant frequency. This causes the neck to vibrate, making the string move erratically.…

Open string sitar buzz after nut slot work

Hi all, new to nut slot work world, please can you help me with this mystery? fret levelling, neck relief and string action adjustment all completed to Fender 9.5" radius spec. very happy with that. the next step: 0.011” High E string’s nut slot was a bit low. I used Dave Johnson’s (MI Guitar Craft Academy) “q-tip slot raising method”: the pulled cotton strand, plus extra thin CA glue, to fill the slot, then trim it off once dry,…

i always use a nut file that is the closest size up from the string gauge. i used a 13 gauge file for an 11 gauge string, and 16 gauge file for a 14 gauge string

Schecter Banshee Mach 6 Intonation at the second fret

I have a customer with a guitar that has an intonation issue. It plays flat at the first and second fret on the D and G string. The factory spec says its a 25.5 scale but I measure from the nut to the 12th fret 12 5/8. I plugged the number for a 25.25 scale into the Stew Mac fret board calculator and the measurement is off from the nut to the first fret. Unfortunately I now longer have the guitar in my possession so I cant tell you exac…

Any way for you to get the instrument back for those measurements? One thing about the compensated nut, is it suggests some factory tinkering with intonation more broadly. It's not uncommon for intona…

Do I need a refret?

Hi, thanks for this great resource. This is my first post here. I work on my own instruments and have little experience with advanced repairs. Recently I acquired a ca. 78 Sigma DR28H. I bought it because it sounded great and came with a pickup installed. I wanted something for open mics and gigging. With light strumming it sounded fine but I found some buzzing when I took it to a jam. I made a nut and saddle , adjusted the truss…

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…

93 Charvel Surfcaster Rolling Nut

Seeking referrals for a machinist or fabricator to replace the bass side of the rolling nut on a 93 Charvel Surfcaster. The original had been lost and replaced with something similar but not the correct dimensions and taper. Thank you, Mark Images

Pedulla Bass Truss Rod

Hello, Looking for any suggestions for replacing the missing hex nut on a Pedulla Bass. This is not a standard size and from limited past experience this is fixed to the end. A flat 5-6 mm nut seems to fit but not securely without removing material under the nut shelf. Thank you, Mark Images
