Thanks. > > Avery Todd, RPT > Houston, TX I tune one Boston regularly that tends to do this, that takes me an extra 15 or 20 minutes to tune because of it. It's a rendering problem. Some of it seems to be at the capo/counter bearing, and some through the bridge. It takes me two passes through the top third, doing everything I can to insure strings are stable, only to have some (too many) move slightly after the first pass. I'd suggest that they have someone in the area that's known for leaving unusually stable tunings give it a shot. Ron N
