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.

Watch the sanding!

By

Verified Buyer


This is the second guitar I've built with this wood and I've found it's easy to crush the fibers with even the lightest of sanding. First top didn't crush as much as the second, so sand very lightly if you can. The wood sounds good, but I probably won't build with this wood again unless the customer wants it.

Yes, Torrefied soundboards do make a difference..

My first exposure to torrefied soundboards was with a D-28 based on a vintage design from the 30's. It is a wonderful sounding instrument. So, when I built a 000 I used a Torrefied soundboard and I also made all the braces using the Torrefied brace wood, I also used hide glue for all the braces. I have to say this 000 does have a presence beyond "typical" ..great tonality, sustain, and as if it is already opened up as a much older well played instrument in a new build.... look all of this is subjective, I can only say I really like using it. I like the tap tones even in the thick un-sanded state and most of all, can't beat the price.

Another beautiful guitar...

I'm really loving the torrefied Sitka spruce I get from Stewmac. No matter what brace pattern I throw at it, the guitar always ends up sounding spectacular. The torrefaction process brings out the beauty of the wood grain and silking.

Not AAA, but OK

the torrefied sitka spruce tops I received were not AAA tops, at least in my understanding of the grading of spruce tonewood. They are reasonable for the money, and I don't see much out there that is better, and certainly not for the price. If you want to experiment with torrefied wood and make your own determination about it's benefits, this isn't a bad way to go.

I have not built a guitar with this wood yet, but it's a decent product. I love Stew-Mac and hate to give anything but the best review, but this is my opinion.

Response from StewMac


John, thank you for your feedback. We are sending you a new top today, hand-picked and inspected by our technicians. We hope you can still use the first ones on a future build. Thanks!

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

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.

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...

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...
