This is an LP copy from Memphis guitars. It looks like it has had the headstock repaired at some point. Also, there is what looks like some separation of the fretboard near the nut. I don't know if its left over from the repair or if its something new and just trying to go this way. I'm asking the group to look at the pics to help me figure out if any corrective steps are needed. Also from a finish repair standpoint, how to deal with i…

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?

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…

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…

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…

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 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…

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…

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…
