Thanks guys for the suggestions. FJ also suggested to run the original RT at half-time. To my ear half-time did eliminate the odd fret noise which was due to stretching. However, I really didn't want to hear any fret noises in my tune.

Steve, I didn't get to try to frequency filter and I will tell you why: I have been doing this long enough that I no longer need to labor in BIAB to get my tracks. I have discovered after 25 years that I can go to my DAW and generate guitar accompaniment with little difficulty. Honestly, for Guitar, Piano and Durms, I find midi in my DAW, with various VSTis, can sound just as "real" as the BIAB RTs but with much more flexibility for composing and arranging permitting me to be more creative.

One BIAB feature which I still like to implement is the general chord chart. I still favor the Chord Grid outline for sight reading my chords over any other option I have found. At least up to now. So while most of my projects still get into BIAB at some point, the heavy lifting is done in my DAW.
