I can do it, I have the technology my friends!
Here's a little sample, The Beatle's "Roll Over Beethoven" with suppresed guitar track.
Roll Over Beethoven was recorded in 1963 onto a 2-track Master Track:
Track 1: Guitar Solo, Hand Claps, Vocals
Track 2: Lead Guitar, Rhythm Guitar, Bass Guitar, Drums
I am able to separate the guitar out cleanly with only a very little amount of bleed. (Note, I left the rhythm guitar in the beginning as that's when you play lead.)
First is with guitar, second is without.
