I recently acquired an X-170 in very nice condition. However, like one I previously owned, I cannot lower the bridge enough to get decent action on the neck. I even removed the adjusting wheels. Action is still high, particularly on the bottom (heavier) strings. I am using D'Addario Chromes light jazz strings (10s). I adjusted the neck so that it is flat (no relief). Still too high at the 12th fret. I would like to get a lower profile bridge if possible but I haven't been able to find one. I realize that the Guild bridge is already pretty low profile. This is the second X-170 I've had with this issue. I have read in some older posts that the X170 neck angle is part of the problem. Basically, I'd like to find an after market bridge that has a lower profile, and that I can tinker with if necessary. I don't want to destroy the original bridge. I have also been thinking that an ebony bridge might be interesting.
