First-thanks guys, for the votes of support. John Luke, you are right that there are many options to cover. But this is a forum, I tried to simplify the header.
The need is for two things: more voicing choices on the existing shots/holds, and additional shots and holds for more advanced chords.In truth, it doesn't need to be a lot, a dozen should be fine, if each has three voicing/performance selections.
Major and minor 6ths and 7ths and the b9/b5 and dim/half-dim options two or three each by the artist would be an enormous asset.
As it is, I can live with muting a guitar shot if the bass is solid, but holds I have to reconstruct in my DAW. Thanks for joining in.
