On the Bench: Western White Spruce/African Rosewood Concert Guitar

...the art of knowing and working with Mother Nature's wood is one of the noblest occupations created for the development and enjoyment of human beings.

Manuel Rodriguez, The Art and Craft of Making Classical Guitars, 2003


We've had a cold snap here in our neck of the woods, thankfully the temperature hasn't dropped below 0 degrees Fahrenheit at the house, but daytime temperatures haven't gotten about 25 degrees F. The relative humidity has dropped and my little humidifier is having a hard time keeping moisture in the air of my new little upstairs workshop, which means I have to watch the hygrometer and the wood very carefully. I doubt I will be doing much glueing until the temps get above 30 degrees.

That said, I have parts for another guitar ready for the bench, a spruce and African rosewood (bubinga).

I bought two white spruce tops from Stew-Mac several years ago, it was a limited time offering, the wood sold out quickly and Stewmac no longer offers this wonderful tone wood.

White spruce - aka, cat spruce, skunk spruce, western white spruce, picea glauca - is very similar to Sitka spruce and even smells like it when you work it. I have found one source for it on the internet, I am sure there are others, but I am not looking too hard.


This five strut bracing pattern is adapted from ones used by Marcelo Barbero, Hernandez y Aguado, and Antonio Torres. It's a experiment for me, I want a looser top with a quick response and perhaps a few more overtones.

I used a beautiful rosette handcrafted in Russia by a father and son team.

Notice the medullary rays present in this guitar top.




This guitar will have a three piece back - bubinga with a Macassar ebony insert.



Bubinga is harder than East Indian rosewood and has a brilliant, glassy tap tone to it.

I think the Macassar ebony really compliments the bubinga.




The headstock overlay for this guitar echoes the three piece back...


The Guitar Foundation of America 2016 convention is just six months away. I already registered for a table at the vendor expo, I have so much work to do to get ready for the show!

Off the Bench and For Sale: Miguel Rodriguez Style Guitar

This guitar has a Western Red Cedar top, Claro walnut back and sides, Royal ebony fretboard, Indian rosewood bridge and a 650mm string length.

This guitar has a beautiful voice and is loud! I was amazed at how loud it is as soon as I got the strings on and tuned to concert pitch. It is easy to play and I am blown away by the musical nuances that can be created with this guitar.

1961 Hernandez y Aguado Style Classical Guitar, Redwood/Indian Rosewood, For Sale

Please note that this guitar is currently for sale at Savage Classical Guitar. Please click here to see this guitar!

I made this guitar several years ago, but because of custom orders, I had to set it aside. I put strings on it two weeks ago and it is a most magnificent sounding guitar! It has good, clear separation string to string, wonderful sustain with evenness and balance throughout with a very lyrical voice. I originally made this guitar for myself, but someone with a good strong technique and a good understanding of musical interpretation should own this guitar and play it on a regular basis.



This guitar is a fairly close copy of a guitar made by Hernandez y Aguado in 1961. The body length is 480mm, most of the HyA guitars had a body length of 490mm; string length is 650mm, many were 655mm and longer; other than that I trie…

Late Summer, Early Fall and a Spruce/Ziricote Classical Guitar

Thus begins what many residents feel is the Southern Rockies' most beautiful time of the year - Indian summer.

Audrey DeLella Benedict, The Southern Rockies, 1991


It is sunny today with bluebird skies highlighting the golds and oranges of the aspen trees.

Fog covered our little hollow all day yesterday, the sun came out at exactly 4:45pm and shone upon us for fifteen minutes, then the clouds came back.



The aspens and ferns in the backyard...



A few wildflowers are blooming, like this harebell...


Our little flower garden is going to seed...



I dropped six ponderosa pine on our property last week for firewood and fire mitigation, as you can see I have much work to do splitting and stacking the firewood.


This is the latest guitar on the bench, a 1961 Hernandez y Aguado style guitar, with a Colorado Engelmann spruce top...



and ziricote back and sides.

I am in the process of pore filling, later this week I will start the French polish.

It has an incredibly loud tap tone, it will be wond…
