Pernambuco/WRC contemporary classical guitar.

[John Parchem]

My last complete instrument for a short time (I promise.) It is just that I had two going on and the scheduled Ukulele class. In any case this is a "Contemporary Classical" Guitar. I get it, an oxymoron. The basic body shape is a Hauser 37 with the cutaway added. The contemporary features are a bolt on\bolt off neck, compensated nut, 30' radiused top. 10' radiused back 24" radius fretboard, 49 mm nut, sound port and carbon fiber reinforced falcate braces.

Three piece Pernambuco back and sides
Western Red cedar top
Cocobolo Bindings and fretboard
Brazilian Rosewood headstock veneer
CF reinforced Brazilian Rosewood bridge
Traditional French Polish top with shellac
Amboyna Burl classical style rosette
Back and sides and neck sprayed with Post catalyzed Royal lac sprayed on Silvertip Epoxy with slow hardener pore fill.
Bright Gold with Ebony Schertler Classical Guitar Tuning Keys.

Very nice John. Was this a commission build?

[Daniel P]

Very cool John. The cocobolo binding with Pernambuco is a great visual pairing.

You know we now want the video and the frequency samples...

Excellent John,
I love those little wooden flaws as in this cocobolo fretboard. It is wood! Very pleasing for my eye. If only guitarist would appreciate that more.
Your guitar is contemporary for sure.
You are very productive. I wished I could find more time for that.
Make us a sound clip, we love that.

Thanks Herman and Daniel. My productivity is an allusion of having a few instruments piled up and finally finishing them. I have nothing but a repair on the bench right now.

I will come up with a audio clip sound. I wanted to wait another week as they settled in. I do have spectrum graphs of the tap for this and the Osage Orange guitar. You will see they are very close. The Pernambuco has a sound port which accounted for the higher Air resonance. I am not sure what the cutaway does to the air resonance T(1,1)1, I do know the sound port would raise it. In any case the Gore techniques are letting me get pretty consistent.
First this one the Pernambuco.

Just closing out this thread. Here is a video my guitar instructor Doug Rice tring this guitar. His main guitar now is one of my falcate classical guitars. Here is his description of the sound he hears from this falcate bracing pattern. "Their superb basic tone color and resonance, especially their high overtones presented a harp-like quality. They exhibited a wide dynamic range and followed esponsively throughout the range, enabling a vastly broadened interpretive menu: for example, piano subitos were not simply softer, but seductively engaging to the ear.The sustaining quality enabled impressive legato lines. The treble-bass balance enhanced voice leading and unfolding rich harmonies."
