I'll be there with two guitars and one virtuoso guitar player (not me, for the record). Definitely say hello!

Paint chip repair, advice for drop-fill in sunburst

I'd like to add some cherry nitro to this spot but how do I avoid the dark line around the perimeter that typically forms from adding a touch-up? I.e., what is the best strategy for blending what i'm adding to what is there?

Difficulty in making repair look better than the damage 8/10. What is your plan for application? Airbrush or paint brush?

L.R. Baggs Anthem Installation in a GS Mini

Hey everyone, I was showing this to James Roadman on the Loothalong, and I thought I’d share it here with anyone who might find it helpful. I was installing an Anthem in a GS Mini, and I couldn’t get the microphone to fit without hitting the ballends of the strings. I had thought about placing the mic on the other side of the pins, but then I decided to use a scalpel and a small file to cut some chamfers into the corners of the mic housi…

GlueBoost vs Nitro drop fill

*Photo added* Ding repair on spruce top, 2015 Collings 0002HE #23701. What are y’all reaching for when repairing dents in nitro? GlueBoost fill & finish or drop filling with nitrocellulose? This is a well-used guitar; not pristine and the owner has reasonable expectations that the repair will not be “like it never happened” Bonus question: If there is bare wood, should I seal it with shellac to preserve the color before proceeding to fil…

The coating on that 000 is a mixture of a UV poly base and nitro top coats. It seems that many of the deeper spots could benefit from steam applications. I use a paper towel, folded into four layers a…

Introducing the NutBuster

Hello All I have been using Ted Bergstrand's online nut calculator on Benchmuse.com which is excellent. It allows you to have a consistent gap between each strings vs the progressive gap that the Stewmac rule gives you. Or you can do consistent centers to the strings. I have definitely found measuring the nut with calipers to work a lot better than the stewmac rule and don't use the rule anymore. I wanted some additional functionality…

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.

modifying waverly tuners

Gibson Roy Smeck Radio Grande 7 string! in for tuner replacements... Currently has faulty original grovers, wants waverly titanium that I'd have to modify the plate shape to fit---and drill a new lower hole mount to avoid new holes drilled in the headstock ( around the "e" in waverly logo; and new plate hole and old plate hole would intersect by a whisper ). I'd have to remove the cog to mill & install, but the mounting screw head has c…

I know you're looking for the best ways of utilizing the Waverly tuners, but perhaps using tuning machines that are a better fit (maybe without drilling new holes) would be a better solution.

Discoloration inside acoustic guitar...

Hey Looths, I have a 1980 Guild 12 string in the shop and while doing a preliminary examination I noticed this odd discoloration inside of the guitar. My immediate thought was water damage, although it hasn't bled through to the outside of the guitar and lifted the finish. I also thought of glue smear but I can't quite tell. Any thoughts here?

When do you guys suggest a bridge re-glue?

At what point do you tell a customer that their acoustic instrument needs a bridge reglue? Do you do it when the corners are just barely starting to lift? Once it has begun to affect playability/tuning stability? Do you offer half-measures to save them money when the damage is not too bad (dripping in some thinned tite bond instead of removing the bridge entirely for example)? I ask this because a Godin acoustic bass just came across my…

You've had better luck than me with half measures. I'm not sure why you're diluted Titebond worked, but the one of the unfortunate things about Titebond, is that you cant glue TB to TB. It could be th…

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…

The only other potential thought I have outside of maestro's James and Ian is, while it's hard to know via photos; has the neck been refinished? I'm seeing some sheen in the worn areas which I wouldn…

It's urethane rubber sheeting. I get it from McMaster-Carr. I think the wooden jaws on the Stewmac vise uses 1/16th" urethane. The Total Vise stuff is typically 1/8 inch. You can also get it in 3…

My guitar got smashed.

It was attacked by a Martin Dreadaught on a small mountain stage resulting in a faceplant. The top is Redwood. I was able to get it to glue up fairly well and have done some splice and drop fill on the vertical cracks. I'm curious about suggestions for the deep cross grain areas. I am hoping to not re-shoot any lacquer and just rub out the finish with some Kovax dry sanding. It was never high gloss buff to begin with and it's a personal…

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…

Thoughts on Restauration Roger Archtop

Hey everybody, I should restore this Roger Rossmeissl Archtop. There is a lot of work to do. The owner is aware of the possibly-much-more-work-than-value situation. I am still thinking about how to aproach it, I want to start working on the guitar in August. It seems that there is not much warping in the top, few wood is lost. I do not know what happened to the guitar, but sometimes I hear a voice coming out the corner of my workshop mumb…

neck reset acoustic guitar with two necks (harp guitar)

I've owned this Jersey City made 12-string/drone 'harp' guitar for a few years and want to get on the repair. I've taken the necks off many dozens of Schmidt-made guitars but never one with two necks. I've searched the web looking for harp guitar neck removal and didn't find anything of use. Asking for any tips/aids/experience from the loothers. My plan is to make a custom neck removal jig that fits the necks, and then drill the typical…

Dunable Yeti with a backwards rod???

Hello! Im working on a repair for a cutsom build for a customer. Its a Dunable Yeti built in 2022. Anyway, all work was going fine till testing the rod... i discovered that the rod is working the opposite of how it should function on any other guitar. CCW is tightening (and no, no a dual action rod) Tightening this rod is adding relief. The guitar already had too much when disengaged. Trying to figure out how to approach this as this is a f…

It could be that the rod is really high on the center mass of the neck. This will produce this effect in extreme examples. This should be considered a probable defect. Are you able to set it somewhat…
