| Come on, guys... tritone subs are so 'bebop'! Yawn ;)
j/k.
I highly encourage you to check out Jerry Bergonzi's book on Minor Pentatonics... for a modern sound. I also have a few methods about minor 6, minor pentatonics, altered pentatonics that eventually I'll get off my tail and put YET another improvisation book out.
Over G7/F7 you could really go nuts ala Woody with some intervallic improvisation! Set a four note "cell" with four intervals... m2/p4/m6/m7 for example.
I also love to improvise intervallically as well as using chords with a half/whole step pattern, ala George Garzone/Bergonzi/Leibman, etc.
Feel free to pm me with questions.
