Saxophonists like Charlie Parker, John Coltrane and Michael Brecker will take your fingers to new places that don't sound spawned by guitar.
Fast trumpet lines sound really good on bass.
Interesting that Charlie Christian got his ideas from Lester Young. Wes Montgomery got his ideas from Charlie Christian. Both of those guitarists influenced generations of guitar players. And saxophonist Michael Brecker was influenced by guitar players (lots of pentatonics). Full Circle.
Yes indeed. I've been using sax, clarinet and cello music for a few years to expand my melodic sensibilities in terms of phrasing, dynamics, form etc, but nothing with the complexity of what you've posted here. Indian classical music has also been a great source of inspiration, as much for it's use of flexible tempo as part of the melodic form as anything else.
