Torrefied Sitka Spruce Soundboard for Dreadnought Guitar

About This Item

Already "broken in" for stability and tone.
Torrefied spruce is dimensionally stable (non-shrinking), with the clear tone and warm color of well-aged vintage tonewood.

Bookmatched sets of two quartersawn halves. When joined they're large enough for a Dreadnought guitar.

  • Each half is approximately 8-1/2" x 21" (216mm x 533mm)
  • Thickness-sanded to 0.125" - 0.130" (3.18mm - 3.30mm)

#4771-U Unsanded AAA soundboards
Approximately 5/32” (4mm) thick, ready for thickness-sanding to your own specs.

About torrefied wood
It takes years for a new guitar to break in, to develop its tone and realize its full potential. As tonewood ages, its cell structure goes through changes, becoming much more resonant and responsive. After a few years, you get the payoff: you begin to hear the sound of a vintage guitar.

With the introduction of torrefied woods, professional builders are giving their guitars a head start on tone. The wood is heat-treated in an oxygen-free kiln, making it highly resonant and extremely stable. It's as if the wood is pre-aged. It looks and sounds like wood that's been broken in for many years.

Excellent product - can't go wrong

I purchased 2 sets of this wood - Classified as grade 3 by StewMac - I found one to be a Mastergrade, tight, straight grained, fully silked and the second was a High 2 - with a little it of wave - wider grained - silking over the inner 25% of the boards. So, on average they are indeed a level 3 grade. BOTH, however they looked, had outstanding tap tone - like a buddhist gong. Both had zero to very minor runout. I can't wait to finish the three guitars currently on the bench and start using this as the top wood. I also will be using the torrefied braces.

Torrefied Soundboard

Verified Buyer


The first pair I received were not a pair, one was flat the other cupped and the grain too wide and uneven. I complained and was delighted to be sent a beautiful replacement. A perfect straight, finegrained perfectly matched sheets of sitka with a lovely rippled medulary rayed surface, bright and reflective. It rang like bells. Stiff and light.

Be careful with this wood. It is very brittle. The first glue join split. I had to replane the edges and rejoin. I will be very cautious with this wood and not flex the glueline again. Although it is intended for a Dreadnought it might be better used for a Classic with fan strutting so that the centre strut can reinforce the brittle centre joint. I look forward to hearing it though.

Torrefied Top Wood

By

Verified Buyer


Ordered this wood for my first Acoustic Dreadnought guitar build. Very nice piece of wood with good grain pattern. Easy to work with & have already installed the Rossette & cut out the sound hole. Don't know if the guitar will sound any better using Torrefied wood but an hoping for the best.

Still happy with Stewmac's torrefied Sitka spruce...

By

Verified Buyer


I've completed my third and fourth Ovation re-top/restoration using Stewmac's torrefied Sitka spruce. Even though both guitars use completely different brace patterns, the torrefied wood really brings out the unique tone of both brace patterns. They both sound terrific, each in their own way.

My only suggestion to Stewmac would be to standardize the torrefaction process so that the wood has a consistent coloration. Both sets were purchased on the same order, but the set on the left guitar is noticeably darker than the set on the right. I do like the tight grain pattern and silking.

Still waiting for the torrefied Adirondack spruce tone wood and uncut brace stock...

Pretty happy with the results

Just strung up a 14-fret Martin-esque 00 with this wood. It did split when I was unpacking it but managed to trim it down and the split ended up underneath the fretboard extension. Definitely handle with care, much more so than a standard top. Although Stewmac is always great when it comes to returns if need be.

The Sitka has some nice silking and narrow grain. A fair bit of runout but not too bad.

The guitar is very resonant. It has some nice sparkle when finger-picked. I used torrefied bracing also. Tall thin 1/4" and unscalloped. The smell of this wood is wonderful. Kinda smells like burnt honey.
I happen to like the "vintage" color of this wood. Both guitars in this photo were finished with Minwax Tung Oil Finish. No toner. No shellac.
I will definitely be building more guitars with this wood.

1978 Ovation 1617-4 Legend...

By

Verified Buyer


I was able to finish the 1978 Ovation 1617 using the torrefied wood and uncut torrefied brace stock I bought and I'm very pleased with both how it looks, and more importantly, how it sounds. I duplicated the forward X-brace from the Stewmac Dreadnaught plans and customized it to fit the Ovation body. The wood isn't as pretty as the set I used on the 1967 Balladeer, but it sounds every bit as good. I will continue to use and recommend torrefied wood. If you want a guitar that looks and sounds like an old one, nothing compares to using torrefied wood. Now, if only Stewmac would offer torrefied Adirondack tone wood and uncut brace stock...

Excellent sound board

By

Verified Buyer


I found that it sands faster than untreated sound boards. The only problem I had was that there was a darker streat about three inches wide on both boards. I set the darker wood to the center rather than on the sides. After carving the braces and tuning the board, I really like the tone produced. I plan to order more of the Torrefied Sitka Spruce in the future.

Very pleased

I was slow to get on board the torrified train, but after using one of these tops I'm a happy convert. I've ordered more and can't wait to use them. I'm very pleased with the sonic and visual properties of these tops. They are are a bit more brittle than the usual Sitka, but no more so than other woods such as redwood.
Kudos to Stewmac for their customer service. My second order of these tops weren't visually satisfactory. I was impressed with their response and the replacement tops more than met my criteria.
