... I have the answer!
Well, I did not originally come up with this answer, that honor goes to Jim D. (no surprise there... lol). I was playing with the FR-8X at full volume using the deep orchestral bass and if I pushed or pulled really hard, I could get the accordion to demonstrate a wierd bass vibration. Some reading in the Yahoo FR-8X forum pointed the issue to lose screws in the bass side.
Taking the lead set by Jim, I followed his guide and even made a couple of improvements. The result is that my V-Accordion now sounds as good at maximum volume settings as it does at all other volume levels.
If you have one and it needs this modification, it is not hard, takes perhaps an hour of your time, some gaskets, a touch of silicone and some blue Loctite and a modicum of care and DIY abilities. Id rate the difficulty of this project a 2 out of 10.
Here is how I did it, pics and all: Accordion Memories - Bass Vibration Fix
