Re: Advice for changing bridge type mid-build

Mario Proulx put a brace very similar to the Musser brace. It helps keep the top flatter behind the bridge when tension is applied to the strings. I forgot he used acronym but it was for ". . . magic tone producer" or something similar. It works. Also, just adding to the rear of the bridge plate wou...

Re: Help Identifying an old Parlor Guitar

Check the detail of the sound hole binding. Does it cover just half way through the soundboard or does it cover the entire edge of the sound hole? Some detail shots of the interior might provide more clues (lining, braces, neck block, etc.). I would guess the inlay on the headstock is an add-on some...

Re: Tap tones for archtop top-plate, help needed

". . but perhaps not as loud as I was hoping." Give it some time and use. Some things take some time to develop. I would focus on the 'set up' to make sure it is as playable as possible and PLAY IT! Tone can vary significantly as you change the pick or strength of attack or a hundred other things.

Re: Ibanez Concord 751

I realize this is a bit late, but have you given any thought to a JLD Bridge Doctor? It was designed to flatten tops of deformed guitars, and it does what it is designed to do. I have used them in guitars that would otherwise have been discarded, and made them playable. This is for the area around t...

That coat was probably a vinyl sealer, very common for commercial nitro lacquer finishes.

Re: Crack repair

A particularly noticeable problem is discoloration along a crack. This is often due to dirt or some other substance getting into the wood fiber, especially...

Re: Can this live again? 1941 Epiphone Triumph

Brian Evans, can you tell what type of finish in on your Epiphones? I recall a '40s Broadway model in my shop about 15 years ago that had some issues to sort. The back and top had loose areas and the finish was flaking. The finish was not effected by lacquer thinner, so I surmised it was a varnish, ...

Re: FP finish repair

There are some people that don't care about other's stuff, and obviously don't care much about guitars. Red cedar is what it is, so either just live with it, put an opaque guard on, or replace the top. Those dents/scratches are there in the wood.

Re: Martin bass guitar

You might call Customer Service Dept. at the Martin factory and ask where you might find such specs. That is what I would have had to do when I was a service center. I never came across one of these so I have no notes about them. You will need the serial number as well as the mode number at hand whe...

Re: Banjola buzz fixing and new tailpiece/bridge?

Oh yeah, you have to isolate the buzz before you can fix it. That can be an entertaining process. Without hearing the particular buzz I can only offer some ideas of where to look. Tuning machines: buttons can loosen, washers under the bushing on the face of the headstock, loose bushing, loose screw ...

Re: Banjola buzz fixing and new tailpiece/bridge?

Have you looked at the Stewart/MacDonald catalog?

You want a glue on type bridge with no pins? Maybe more like a classical guitar bridge? What sort of structure is on the inside of the soundboard? 5/8" is pretty tall for a glue on, but much more realistic for a floating bridge.

If you are operating a repair service the Bridge Saver from StewMac can be a real money maker. I used to charge $25 per hole, or $100 for repairing the whole bridge plate. It sure beats removing and replacing the whole bridge plate. The exception would be if the hole has been excessively eroded, in ...

Re: Fixing separated neck laminations, any tricks out there?

David, you say one wood is standing proud, is that because it has shrunk more than the adjacent wood? If that is the case then there likely is shear stress along the whole glue joint if it hasn't already let go. Just trying to visualize the situation, to re-do the joint would require a lot of work b...
