The thing I noticed with tonex and the pa is that patches that sounded good in the daw isolated vs daw mixed vs playing at home through frfr vs playing through poweramp vs playing through frfr with a band were ALL different... so good luck!
A lot of the patches that sounded bad at home did the best with the band, go figure.
Its good to have options though, would be nice to be able to test a bunch in context as much as possible. PA speakers will sound different as well but hopefully you can get a good all-rounder.
