I live not to far from you, in Sterling. I have a BFR Roasted Neck Bongo 4 H. With it, I have had to make adjustments to that neck as well because it was having extreme changes even though I kept it in a climate controlled room but when summer or winter would arrive, the neck for some reason kept adjusting one way or the other. Now with my other roasted neck, my PDN Honeyburst Bongo 4 HH, it hasn't had a single issue so it may have just been that one neck acting weird for a while because we just hit extreme winter and I was naturally expecting to have to adjust the neck once again but so far it has remained stable. With mine, in the winter, the action would raise very high off of the fret board so I would have to adjust it back but then when summer would hit, everything would go back and the strings would almost be touching the frets so I would have to adjust it again. Then when winter hit, it was more high action and vice versa in summer again. But like I said, this year everything has been good on that bass so maybe the neck just needed a few years to settle but that is only a guess on my part. In any event, it has always been an easy fix that only took seconds to take care of and EBMM customer service has been awesome because I always called them afterwards and they would help me out.
