Thanks for the posts, definately some good advice for those adventurous enough to strip down the bridge. I have taken a lot of photos during the strip down and re assembly, is it possible to be an Alembic geek !!! Prior to the strip down I did check the intonation and did seem pretty good, I even measured where the point of contact was on the saddles, even they were back to front, so during the rebuild of the bridge the saddles were adjusted to a pretty similar position just to reduce the amount of adjustment, no point in having them all the way screwed one way or the other, but a good point is the position of the A string, I will attach a photo of the tail piece which is not fully central, this is how it came from Alembic and the photo shows the original screw holes, I am wondering if it is crucial to relocate the bridge slightly to bring it into centre alignment, any thoughts ? if it works all be it slightly off centre then should it really be moved, sorry is this might be a geeky question ? I have checked the position of the tailpiece with it moved into a central position relative to the bridge and there is still sufficient clearance to get a ball end hex driver in place to adjust the A string saddle. Again many thanks for sharing, great advice, many thanks Andy
