feedback on Les Paul Headstock repair

I need some suggestions from the many great repair senseis out there.The customer is fine with a structural repair and not concerned about making it invisible. I told him you will see anything I do. He was fine with that and has a budget of between $700-1000. It's a clean break. nothing missing, It closes tightly.. I was thinking either 1) the generic double splines one on either side of truss rod and touchup as best I can. Or 2) the ab…

With a break like this with plenty of surface area, I would just glue it without any additional supports. My glue of choice is hot hide glue, but there will be lots of opinions on that and many option…

Sad Old '71 Hagstrom Swede

Greetings Wise Elders and fellow seekers of the Looth Group! I hope you're all keeping well. I humbly beseech thee for thine sage wisdom and experience. I purchased a 1971 Hagstrom Swede. This guitar was basically put in a case and then forgotten about for a few decades. I felt sorry for the old man and have taken it in as a stray / project. I would like to get it playing again. There are many scars on this guitar, I have looked for as…

70's Tele Neck w/ truss rod issues and a bulge behind first fret

I've got a client with a '72 Tele. It needs a re-fret, but the truss rod isn't functioning. In fact it's backed out of the channel significantly, and there's a bulge in the neck underneath the first fret which suggests to me there's something going on with the truss rod anchor. The puzzling thing is the wood in the neck has bulged, but the skunk stripe and the finish don't appear to be disturbed at all. I'm thinking I'll probably hav…

Bass Neck Stiffness, Can't Get Enough Relief

Hello, I hope everyone is having a great 4th of July weekend so far. I was recently asked by a friend to work on a cheap S101 bass someone had given to him. It had no electronics and it was severally back bowed. After finishing up the electronics, I did the set up. He wanted the guitar tuned low, to Drop C. So, I went out and bought some Ernie Ball Power Slinkies 55-110. Once I got to the nut depth check, it was clear there were large, g…

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?

Help needed to pinpoint my mistakes please!

Hi all, I am a newer guitar tech and after dozens of repairs this particular Simon & Patrick Luthier Cedar top SP6 acoustic dreadnought from the 90-ies with a bolt-on maple neck has been an incredible challenge. It came with a maxed out and stuck truss rod with a considerable up bow in the neck, extremely low saddle with barely any string break angle, so it needed a neck reset. Later on I figured out that it also has a pretty dras…

What do you do when you get a knock off guitar on your bench?

I have a "fender", which I believe is a knock off, in my shop. I didn't immediately catch that it was a fake, but as I worked on it it's become fairly undeniable, in my opinion. For the neck — the fretboard is made from two pieces of rosewood, the headstock decal doesn't look right, the truss rod is metric, the tuners don't look like a MIA Fender, and there's no walnut plug on the truss access. The model name being wrong is suspicio…

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.…

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…

1950's Gretsch Neck Reset

I had a vintage Gretsch semi hollow come through the shop this week and it's left me with some questions. First off identifying the instrument's model has been a trick so far. The only information I can find is that is was likely built in and around the early 50's Second, it's in need of a neck reset. I'm not particularly well versed in resets for hollow and semi hollow guitars, especially one of this age and design. I'm very curious…

That neck is coming off because it wasn't put on very well when it was made. In my opinion, slipping some glue in there and trying to clamp it shut will result in the next guy (often you) having a har…

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…

Pedulla Bass Truss Rod

Harmony H167 Neck Reset...

Hey everyone, recently I've been getting more requests for neck resets from customers, and up until this point I haven't been offering them since I don't have the practical experience. I'm keen to change this, and I've borrowed my fathers Harmony H167 that has seen better days. I've done an initial cleaning and assessment, the truss rod works although I may need to force it into a backbow to have a fully adjustable neck. This shouldn't…

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…

Can't access truss rod

I bought a boutique guitar, used from Guitar Center. I really want to like this guitar. I just got it a couple of days ago. Looking forward to doing a setup. The neck is straight. I went to add some relief and found that the wood around the truss rod keeps the 4mm hex key from engaging. Any suggestions on how to hog out enough wood to get access? I was thinking of superglueing some 180 sand paper to a 4.5 mm hex key and sanding the…

If I really liked it (or it was a client's guitar) - I might go fearless with a drill bit on a low setting to remove some material for access.
