Yes, Gibson fans, J-45s are nice (although I find the thinner finish on the J-50s often lets the sound have a bit more life, and I have read the same of the WM45s too) but they are not usually the weapon of choice of those using varied open tunings, where the extra resonance of say a Lowden may be the better tool for the job. The ladder bracings tend to sound shorter - maybe even "bluesier" - still.
