D28 blowout

Hi all, I'd like to get some input on how to address this top blowout. For starters I own this, I got it as a project guitar, 71 D28. I'm not as experienced with acoustics as electrics and this is a big project but I got it to learn new skills and I'm confident I can do it with guidance. It had been stored in the case for many years under tension and was way too humidified. The bridge had pulled up I assume in stages. The center seam se…

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…

Thanks so much Ian, much to consider. Your tip about the white glue is something I didn't consider at all.

Physical management of work-in-process instruments

A growing work flow in a small shop means I have in-process guitars stacked all over my work surfaces. I need to protect them and keep all the pieces together but also to have them readily accessible, and cases are less than ideal for that. Never mind the caseless guitars. I'd be grateful for advice on containers/stacking/shelves to protect and organize the growing mess. Thanks!

If you have the room to go 48 inches deep, this was our solution. Stores lots of projects and all the drawers slide out. Just like at the morgue.😉🙃 Of course you don't have to make it as tall as we d…

Off-Gassing

Any tips on handling the off-gassing for vintage guitars? I just took in a 1941 D'Angelico. The original tortoise shell pickguard is gone and has been replaced. New case as well. The frets up the neck are going to need to be cleaned. But are there any other precautions I should tell the client to take? Anything I should take into account? -Mike

The consensus seems to be to leave it out of the case so the off gassing doesn't create a gassy feedback loop with the existing plastic.

Martin D-35 with cracks everywhere!

Hello looths! Long time lurker, first time poster here all the way from New Zealand. I have recently acquired this 2008 Martin D-35 for a very cheap price ($1000 NZD - around 600 US!) it's dried out in a very cold environment and has two substantial cracks running all the way across the top, one large side crack, and a previous side crack repair that's been done quite poorly. I'm only about 3 years in to this repair journey and this is d…

I thought I might add an outlier of an opinion here. I understand the temptation to close the cracks with higher humidity, but you're asking a lot of adhesives, reinforcements and human attention span…

PBass has been stripped of it finish… looking for expertise, friends!

Hi friends, I just stumbled upon a 1966 P-Bass, nearly completely original. The owner bought it in 1971 and it had already been stripped of its original finish. That was a thing back then. You can guess that 55 years of gigging had the wood absorb much of the owner’s DNA and sweat. Maybe a few beers as well. Surface was quite tacky as you can expect. I cleaned it with naphta and StewMac’c brand-new cleaner (quite a great product I'd say…

Ill chime in. Go with shellac first. It may be all you need and if you decide to go with something else, youve already applied the universal seal coat. Also, it has the best chance of sticking to any…

Tremolo issues. Not returning to "zero"

Hey guys. I guess this is an old topic, everyone talks about it but I haven't been able to find a definitive solution for this. Here's the deal: I'm working on a PRS Silversky that has this old problem that when you use the trem bar, one string (G in this case) goes sharp. I made a few adjustments to the nut as we all know that's the first thing to look at...no good. This guitar is new so I'm pretty much ruling out the bridge and posts si…

Local Thrift Shop Find: Gibson Ivory Top A3 Mandolin

A customer brought in a Gibson ivory top A3 mandolin. It's in good shape and has all the parts. He found it at the local thrift store here in Bishop. He wants it mechanically sound. Here are the problems: 1) Everything that comes into the shop has a shrinkage component and the effects of course very from instrument to instrument. This instrument is no exception and the results of that shrinkage, in this case, are severe. The top, ba…

Hi Tom and John. We're trying to slip the glue joint and heat the lignin in the fingerboard. Lignin is a natural glue in wood that holds the cell structure together and acts much like glue we use and w…

Fender, Schmender

Since most of us fix or make guitars, we have probably heard something about the cease and desist letters Fender has sent out concerning the Stratocaster. I thought I would offer some thoughts. As always, caveat emptor. There are three basic ways to protect intellectual property under Federal law. Patent, trademark, and copyright. Each protects different things, and has different underlying legal theories. Lets begin with pate…

There is also a time limit to both Patents and Copyright (and Trademarks, though Trademarks can be renewed). Don't know how long they last in other countries, but Canada is normally 20 years. Copy…

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.…

Some questions on a Taylor Acoustic...

I have a Taylor Acoustic in for a setup and I had a couple of questions: 1. My main one is how you would go about gluing the label back on? I'm probably overthinking it but I'm curious if there's a universally recognized way of doing this? 2. I have some very minor finish damage which I'm not planning on touching, but I am curious how one would go about repairing it. Would this be a case of drop filling lacquer? What would be the…
