With information gained by their experience and research on the AO1 process, inventor Frank Sanns has now developed a physical device that will greatly enhance the tonal and response properties of acoustic instruments and give luthiers more design freedom when designing and building their instruments. The new device is patent-pending and will be available both as a standalone, aftermarket accessory and as an integral component on new instruments. AAL has begun collaborative work with key artists & manufacturers in the acoustic instrument market. Plans to unveil private and licensable prototypes will roll-out in the second quarter of 2011.

This month, in response growing interest in their efforts, AAL has released a new level of details about their proprietary, patent-applied-for AO1 acoustic optimization service via their website, http://www.alchemyacousticlabs.com.

After an instrument arrives at AAL, the AO1 Process begins by a thorough visual inspection followed by sonic and tactile impressions made by one or more guitar techs and/or players.

After the initial evaluation is completed, the instrument is placed in an anechoic chamber and a proprietary sensor system maps the input and output response of the primary sound forming surfaces of the instrument. The I/O response is then used to establish unique process parameters that will be implemented on each individual instrument.  Just as no two instruments are the same, the AO1 process is custom calibrated for every instrument.

Once the process parameters are mapped, various locations of the instrument are targeted and then are  non-thermally annealed by focusing high energy sonic waves of extremely specific energy levels at corresponding specific  locations on the instrument while response measurements are tracked simultaneously.

The AO1 process allows for symmetrical, properly located oscillations to occur in the sound-forming surfaces of the instrument and manifests itself in greater volume/dynamic range, richer, more full sound, and greater responsiveness to the player’s touch.  Over the course of the following 4-6 weeks, the instrument will continue to transform  to its full 100% potential assisted by frequent playing.

AAL  has processed instruments for multiple large-scale manufacturers and modified versions of the AO1 process are available for manufacturer’s licensing.

We bring this up not so much as a promotional vehicle for us (don’t get me wrong, we’d work it if we could find a way, but it was only a name drop, not a cover story!) as much as to point out a well-structured bit of journalism about a topic near and dear to our hearts here.  The article discusses the properties of aging that directly contribute to the changing of an acoustic guitar’s sound.

A quote from the article:

“There is no question that stringed instruments change as they’re aging and are getting played. On some instruments, the changes people detect are dramatic, while on others they’re more subtle, making it difficult to predict the sound a new guitar will deliver in the future. For these reasons, it’s best to not count on specific tonal improvements when purchasing a new guitar, but rather to choose one that sounds great to you now; think of anything else as icing on the cake!”

Which is a seemingly obvious yet, surprisingly crucial statement that we firmly support. What we’ve said about our process from the beginning, that it’s YOUR guitar, only moreso – is still behind everything we do. We wouldn’t have the level of customer satisfaction that we do now (100% by the way) if we made people’s guitars sound like other guitars. You picked your guitar out with emotion and great care. What we do is to take your guitar to ITS fullest potential. Not make it sound like something it wasn’t meant to be, but rather exactly what it WAS designed to be, someday in the future.

We’re happy just being mentioned in the article, even if it is in the same breath as a couple device-based gizmos that throw a wacky one-size-fits-all, “Flowbee” shroud over the science of what we do. (It’s okay, we understand. $149 is hard to pass up. We’re not saying they don’t work, in um – their own way. Talk to us about it sometime.)

One thing the article talks about that we wish we had the chance to respond to formally is this notion that even in the best lab testing they’ve devised, these are super-subtle effects that human auditory memory can’t even discern between because ear memory dissipates so quickly – yadda, yadda.  Um, respectfully -  no. Maybe if you’re trying to compare two “same” guitars (note – the author does allow that no two guitars are ever truly the same, but they still used the reports from the test) or sticking an aquariam vibrator on your guitar for a 100 hours,  or just asking unassociated players which guitar tone they like better – you’ll get some varying results that could be attributed to the poor human ear memory. But we haven’t had one customer yet report back anything less than dramatic transformation in volume, balance, sustain etc. from our process. In fact, it’s been blogged about independently out in the world. More importantly, we’ve captured and graphed those unsubtle differences with our data measuring equipment. let me go further and add what we’ve said all along – if any notable publication (like AGM, for example) wants AAL to put our money where our mouths are – we’ll process a guitar for free for their scrutiny, or take part in a test or shootout.

Let’s talk.

Frank brings the freshly AO1-optimized Rodrigo Moreira Hauser replica classical guitar back to Porsche specialist John Raysich, at his repair shop (John Raysich Porsche Specialties) in Pittsburgh, PA.

This guitar has an interesting story. Moreira was commissioned to do some restoration work on Segovia’s 1931 Hauser I guitar. Having one, if not THE most prized classical guitars in the world in hand, Moreira decided to build a replica or two….

It’s February, which was pretty brutal this year in Pittsburgh, and John was busy at work, in coveralls, with beepers and phones ringing and mechanics asking him questions while he tried the guitar for the first time after being processed. So – as usual, we present a very candid, un-glamorous look at REAL customers’ REAL reactions when they get their instruments back.

The Julius Borges OM-28 was one of our favorite guitars we’ve ever played or had in our labs. The build quality and playability is just phenomenal. It was already optimized for volume, versatility and projection by design when we received it.

Post AO1 process, it did not come up as dramatically in amplitude (volume) as some other guitars we’ve processed. It had more increase in sustain than volume. But where we felt that the process enhanced its sound the most was in the evening out of the notes, filling in the bottom end in the lows and low-mid ranges. It truly opened up the guitar in the way that age and playing (a lot) would do.

We’ll post updates to this guitar as the story continues to unfold. For now, here are some audio and video files chronicling the event.

From the moment it arrived, we all liked the guitar very much, but according to David, it was his least favorite of his three Collings dreads. We heard the opportunity to help it reach its full potential and were eager to let the process do what we expected it would.

You can watch the video below (or on the Videos page) of Jim Relja and us examining the guitar before and after the process. The process added much more sustain and it really filled out the frequency range in the lows and low-mids.

One of our usual go-to reviewers, Jim was knocked out by both this guitar and by how it transformed after being processed.  “I’ve never heard sustain like this on a guitar. This is ridiculous…”

We sent the guitar back to Collings and waited for David to get back from the road to check it out. His immediate responses were good, but he waited a few weeks to give us his full review:

“The process has made a noticeable change in my guitar. It always sounded good, but was my least favorite of my 3 Collings Dreads. Now it seems louder and punchier, and doesn’t “cave in” at all when played really hard…..and holds it’s own with the other guitars which happen to be exceptional. Thank you again.”

We’re extremely lucky to have one of the best-stocked high-end acoustic guitar shops in the country, manned by one of the most knowledgeable, passionate guitar dealers in the business, right here about 5 miles up the river from our headquarters. We have no connection with Steve from Acoustic Music Works, (other than being regular customers) but I can tell you his hand-picked instrument selection is unsurpassed.

We see our share of off-the-charts high-end guitars through here and I have to say that Bourgeois makes some of the finest playing instruments available.  Frank chose this gorgeous Bourgeois Advanced Slope D Premium Madrose from Steve’s stock because of its stunning tone and beauty. This is a player’s guitar.

This video is another casual behind the scenes discussion with Jim Relja playing and reviewing the guitar directly after it had been AO1-processed. the guitar has since opened up even more in the 4 weeks since this video was shot. You’ll hear one of our returning customers, Pat, asking Jim questions about the process in this clip.

Some days I have the best job on the planet.

We met and talked with so many exceptional builders and performing artists about sending us an instrument to put through the AO1 process,  (you know who you are!) thanks to all of your overwhelmingly helpful input, advice, interest and/or participation, 2010 is looking like a big year for Alchemy Acoustic Labs.
