Post subject:  B-3c German spruce / EIR

I haven't posted pictures in a long time, here's a small (00 size) 12 fret cutaway. Built over a year ago and put together last month. Some new features for me on this one: adjustable neck, floating fingerboard, double sides, solid laminated linings, shallow peghead angle. There's a small audio sample: C G D G C D.

German spruce top
EIR back & sides
Honduran mahogany neck
Ebony FB (with CF rods running in the FB and neck)
Braz bridge, headplate and butt wedge
Cocobolo trim
Bone nut, saddle and pins
Grover Sta-Tite tuners
25.59" (650mm) scale
1 3/4" nut width
2 5/16" bridge string spacing
Oil varnish

Laurent, beautiful guitar! I love the boxed end graft and back strip.

What is the angle on the neck? Is it a 90 degree?
It is hard to see the extension also, is it black wood flush to the FB or is the FB floating?
It looks like a new heel shape for you also.

I am working on a guitar now with many of these same features. I am interested in the CF in the FB. Is it tall pieces that extend from the neck into the FB or separate pieces?

I wish I could see and hear it in person, everything looks great. The varnish especially!

hi Laurent
a very elegant wee guitar, I like the 12 fret cutaway size and the idea of floating the fingerboard. It certainly handles the C-G in he bottom well and nice tone / sustain in the trebles, lovely work
yours Geordie

Laurent you are one monotonous guy - every guitar you post looks dang nice!

Would you share on the lights used.

Lovely work Laurent. I also particularly like the back stripe and butt wedge. Adjustable neck à la Rick Turner?

Lovely guitar. Gorgeous perfs and rosette!

Care to give us a tutorial on that rosette design? Eat Drink

Beautiful and restrained guitar, Laurent. You mentioned a shallow head angle. I have used 12 degrees for steel strings and am thinking of going to 10 degrees. What angle did you use?

What a huge sound from such a small box...impressive!
And, I really like your aesthetic sense, Laurent.
Beautiful work as always--thanks for posting.

Wow Laurent! Amazing!! When I heard the sound clip I couldn't believe such a huge sound was coming from a small guitar. What a gorgeous tone coming from that box! I'm curious.... what microphones, pres/interface were used? And if it was more than one mic, what configuration? Besides being a very talented luthier maybe your second vocation is as a sound engineer? ;)

As usual, beautiful work Laurent. I'm curious as to your opinion of the floating fingerboard; any noticeable difference in tone or response?

The multiple line binding on the fretboard complements the boxed trim very well. Masterfully executed and a fine instrument. My hat is off to you...... [clap] You set our standards very high...

Neck angle is 90º to the sides, the upper bout on the top slopes gently to accommodate the elevated FB extension. The black you see are the 2 x CF rods under the FB. They're .125" x .375" CF and come from Jim at Los Alamos Composites, they're dadoed about .125" in the FB .800" apart, the rest in the neck stock, à la Rick Turner. I have to say that the truss rod has some minimal effect, the neck structure in incredibly stiff. Which is great when switching tunings constantly, as I do.

I am not sure I understand the question, you mean to take the pics?

Dave Higham wrote:
Adjustable neck à la Rick Turner?

Yes, more or less. Parallelism/scale length is done before the neck goes on with two 10/32 inserts on the upper bout. This one still has a mortise/tenon neck joint and the adjustable bolts are accessible from the neck block through the soundhole (one to set the angle, the other to lock the neck). I am working on two Stauffer-inspired guitars where the bolts are accessible on the neck heel, like what Rick does. His is, I believe, the best and most elegant method at adapting the Stauffer joint for a steel string.

Flori F. wrote:

Maybe one day when I find the time… It's exactly the same principle as making a wheat pattern, or herringbone, except the angle is much shallower. I think there's a good tutorial on making wheat purflings in the Bogdanovich book. I use another method.

I think 13º, I wouldn't use shallower than that on a paddle peghead.

2 x small cardioid microphones about 1" apart, one toward neck/body joint, the other toward the bridge. The guitar is between 1" and 2" in front of the mics, I orientate myself until it sounds just right, meaning it is as faithful as possible and the stereo image is balanced. That goes into an antique dual G4 via a TC Konnekt audio interface, 44.1KHz/24bit recorded into Logic Pro 8.
I was indeed a sound engineer long before going into lutherie, still am I guess. I produced/mixed/mastered a fair amount of CDs, including my own electronic music of (almost) the last millenium.

No, but it is drastically stiffened by CF rods running under the FB extension full depth.

She's a stunner, Laurent. Exceptionally tasteful - a lovely little guitar with a glorious voice!
