As a followup, I don't use an incident light meter for guitar shots. I just relied on the on-board reflected light meter within the camera.
The camera I'm currently using is the Sony RX-100, a pretty high-end compact.
In the past I've had pretty good luck with our Canon A720, which is totally fine for still-life-type shots. The RX excels at focusing speed and minimal shot-to-shot delay and flash recharge, which are imperative when trying to capture action shots of my toddler (with a toddler ALL shots are action shots!).
I took a look at the link posted by Nomad, and one thing I really like about those is that the background is blurred (wide aperture) so the subject really 'pops', and that the blurred background contains complementary items, other guitars, that work well with the composition on the whole. If you're unable to 'eliminate' background clutter by using felt or another backdrop, the next best option is to blur it and include complementary objects.
