I think there could be other ways of accelerating breaking in, maybe more effective. The Tarhead transducer may be a way towards that!
What I first saw used was this huge bongo like looking thing that shook the whole guitar like crazy. Timber Tech it's called. Lot of reports of that thing helping out too!

Here's a print out for Laurence Juber Taylor(one heck of a good guitarist BTW saw him about a year ago)

The straight line represents the frequency response at the peghead before the shaking; the jagged line shows the response afterward.
This was from an article in
Acoustic Guitar magazineI don't see a lot of Luthiers getting one for their shop
