Thanks for the info. M. I don't know much about any difference, if any, in the bracing of the X700 vs. the x170 or x180, all I know for certain is the lower bout size of the 700 is larger (17"). It would make sense about a difference in the bracing. With regards to amp volume, position, etc., I have tried numerous different settings in attempts to induce feedback and have found (so far ) that I only get feedback if I really WANT to get feedback. No problems with situations where it appears unepectedly. Just double checked the guitar, yup, no soundpost. While surfing the net for info. on the 700 I did come across a review that stated the following:
"An elegant and resonant working jazz box, the X-700 has a sleek neck profile and a full-depth body that is notably feedback resistant."
It's the "noticeably feedback resistant" statement that I am inclined to agree with. I guess my question remains as to "Why?" Is it the bracing as you suspect? Something else? Guilden Magic? Just curious.
Thanks again,
Dan
