I heard some truly awesome fiddling at the Red Shoe Pub in Mabou last time I was there. Good food too. The original Cajun country.

Re: New 17" archtop

An interesting thing I discovered with this guitar (at least I think it's interesting) is that I can get a strong helmholtz resonance from the body by blowing over the sound hole, just like you would with a jug. Of course I immediately tried this with my round-hole flattop guitars, and it didn't wor...

Re: tone and volume on top plate actual effect?

Don't know how pertinent this is to your inquiry, but I built this fully hollow carved archtop with the intention of making an electric guitar, with only enough acoustic sound to hear myself practice. That's pretty much how it turned out, but even with the thin body, maple top and hole-mounted elect...

Cool instrument, Chuck! How is the extension for the two bass strings attached to the neck? And what does your neck block look like inside the guitar?

Re: Help with D'Angelico plane

Steve, I haven't tried the full-size turbo planer, but from what I can see, it looks better suited to flat surfaces and shallow angles. The mini turbo planer works well on an archtop guitar, especially in the tighter curves at the waist. I think you have to use the extension arm with it. I don't fin...

Re: Help with D'Angelico plane

Good advice above. As an archtop guitar builder, I'll add a plug for the Arbortech Mini Turbo Planer as an excellent tool for the roughing-out work. I discovered this after trying many other methods, and I think it's probably the best option short of a big CNC machine. It takes off wood really fast,...

Re: What is the feature of good transducer

What I've noticed many times with folks who play amplified music is that many of the musicians have experienced hearing loss especially in the high frequencies and that absolutely colors their judgement when it comes to choosing what they think sounds good or "right" to them to the detriment of wha...

Re: New 17" archtop

My thickness estimates are not very reliable. I'm much more the intuitive rather than metrics-driven kind of builder. And as D'Aquisto pointed out, the measurements are going to be different for every piece of wood anyway, so you just have to develop a feel for it. I'm pleased that with this guitar,...

Re: What is the feature of good transducer

Is there such a thing? I've still never heard one I liked. I much prefer the sound of magnetic pickups on acoustic guitars, even though they don't reproduce the acoustic sound. Of course microphones are the best option for that purpose.

Re: New 17" archtop

How thin is 'thin'? Also, do know what the top tap tone was before and after you tightened the strings? Unfortunately, I get carried away and forget to measure and record things as carefully as I should. But I know I carved most of the top to a uniform thickness of just over 1/8", except for a slig...

Re: New 17" archtop

Thank for the nice comments! I hope it holds up to the string tension over time. I carved the top thinner and braced it lighter than I have previously dared to go. I think that paid off in sound quality (despite some conventional wisdom to the contrary), but only time will tell if the structure is a...

Re: They said it couldn't be done (truss rod tool)

I've been using those low-profile rods too. I like them so far. I use round-nosed router bits - a 1/4" for most of the channel, and a 3/8" for the end part with the weld and allen wrench socket. I may be losing a few millimeters of wood vs. the counterbore technique, but it sure is easy.

New 17" archtop

I just finished this 17" archtop. Cedar top, cherry back and sides, cherry/padauk/maple neck, cocobolo fretboard, headstock veneer, tailpiece and finger rest, ebony bridge. I was trying to get a little more bass response on this one, and succeeded somewhat. The air resonance from the soundhole is ab...

Re: Burst and French Polish?

Shading on violins is often done using transparent 'lakes' pigments. Lakes are made by precipitating alumina in a dye solution. Some of the dye is incorporated in the colorless and transparent aluminum oxide particles, which protects the normally fugitive colors from degrading, and makes them perma...

Re: Banjo saddle moving

No, don't glue the saddle (bridge) to the top. It's meant to be held in place only by the pressure of the strings. If it's moving lengthwise (parallel to the strings), that means it's too loose. This could be caused by (1) the head needing to be tightened, (2) the neck angle needing to be reset, (3)...

OK, the visual aides on the UNSW physics website finally managed to clear up some of my confusion about the relationship between traveling waves, standing waves and modes of vibration: http://www.animations.physics.unsw.edu.au/waves-sound/oscillations/index.html#1.6 http://newt.phys.unsw.edu.au/jw/s...

Re: Graduated thickness of top plates

Well, I'm out of my depth here because I can't do the math. I have Gore's book, where he explains how traveling waves work in strings, giving the illusion that the string is simply moving up and down, when actually this effect is created by a wave moving back and forth along the string in both direc...
