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…

My opinion is to avoid mission creep. Repairing instruments and authenticating instruments are two different jobs. Only one of these jobs are you actually being paid for. I've never experienced any up…

Replicating Kurt Cobains 59 Martin - bad idea?!

Greetings fellow Looths! I recently received a request from a customer to replicate Kurt Cobains 59 Martin, starting with a Sigma DM3. I have pasted the customers email to me below. While I have been a looth hobbyist for many years, I just recently opened my official business, Finger Lakes Guitar Works, and am just getting off the ground and a good flow of repair work is already coming in. While I feel 100% confident in my abilities to…

Seems kinda annoying to me. The guy wants to spend a ton of money building a replica of a guitar but he's going to not use a guitar by the actual brand to do it? I'm going to go with this is going t…

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…

neck reset guild 512

Hi, I should do a neck reset on a Guild 512B from probably 1973. I have done neck resets before, but this is the first on a guitar that has some value. I want to look out for information about this specific model before i start working. Has anyone done a neck reset on a simular model? What kind of neck joint did they use, and what are the dimensions? Is there anything specific to look out for? I will probably not start working on the guitar…

Great answers from Ian and Tony!!!! If you can paint some reducer around the joint, wait until it activates and cut the nitro with a scalpel it will improve your chances with the finish issues. You'll…

Kamouraska Classical 1979

This is a Kamouraska classical guitar, model 111, made in Canada in 1979. Internet information says it was made in La Patrie, Quebec, and later the line became La Patrie guitars. It looks like someone has been into this one before as the dovetail fit was poor, the gluing is very sloppy, and there are some rough chisel marks on the face of the heel. Note that if you drilled holes at the 13th fret you would miss the pocket by a few mm. Th…

Fretboard hump above fret #12

Is it a common problem for the fretboard on an acoustic to develop a hump around Fret #12 and higher, where the neck meets the body? If so, what is the cause, and is there something that can be done, or avoided, during the initial build process? I have two quality Zager brand guitars that both have the problem, with the problem being worse on the cheaper model. I am a newbie to fret dressing and lowering, so I first tried adjusting the…

Thanks for a great answer. I am a retired sonar engineer, so your explanation makes perfect sense to me. I figured it had to be almost an endemic problem with acoustic guitars.Next question: Can you r…

The first tool to measure longitudinal neck torsion/twist - the LTwist® gauge

Dear looth community/colleagues around the world, During 2023/24 I have developed a digital gauge to measure so-called longitudinal twist of (bass) guitar necks: the LTwist® gauge. Just to be clear, this is about the "cork screw" type of deviation along the length of a neck, not the bow of a neck. I think there is no need to explain how a too severe neck twist can make it difficult or even impossible to set up a stringed instrument (guita…
