The collaboration of guitar and organ has long been embedded in jazz. The tone and the timbre of the two instruments make a very good blend in different contexts. Also, being that they’re both electric instruments, players can command their dynamics. On the guitar they have touch, which gives them control of volume and articulation, but they also have the volume knobs to make the signal louder or softer, which is the same as the organ. I use a volume pedal a lot when I play, and basically that’s an organ thing. They are definitely in the same family.
