Good question Alan, and yes the change in the action can happen after adjustments. It sounds like the strings are raised higher off the fretboard which will add some stiffness to the playing action. Personally I offer very low smooth fast action and I love the E first 9 guage. But it is a matter of personal preference. Lower string action can be achieved if the technician will take careful time to do it. Sometimes it takes several sessions of these adjustments until the neck has finally settled in. I did an expensive Gibson 355 that took 5 times to get it right over a period of about one year. It was my own personal guitar at the time back before I started building my own guitars.
