Jim, (it's Olson, by the way) is a good friend of mine, and he makes amazing guitars. Of all the small shop builders out there, his have by far the best fit and finish. The sound of his guitars is very much in the lightly built, heavy overtones style. To my ear, they are a little "new age" sounding, but that's just because I'm used to my dad's guitars which are much more traditional sounding (i.e., they are built a bit heavier, and have a stronger fundamental, a wider dynamic range, and can be pushed harder than a lighter built guitar). This is not a matter of one be better than the other - just different - both are good, and Jim's guitars are fantastic at what they do. Also, my language in this paragraph is very heavily colored by the fact that I have a strong preference for more traditional sounding guitars. If I had a preference for the more modern lighter guitars, my language would be much different.

Light, IMHO, I'd say your characterization is definitely the case for his current guitars and the ones he has been building for at least the last 10-15 years or so. Some of his early guitars, however, do sound more "traditional". As a result, anyone contemplating a used Olson really ought to play it first, especially if it is one of his older guitars. The sound might not be excatly what you expect. On the other hand, I've had the opportunity to play a variety of his guitars - old and new, and they've all sounded and played just great. Different in some cases maybe, but great nonetheless.
