Yeah, I troll a bit with the comment. Clapton is really good IMO, but his status as a guitar god makes little sense. Garcia repeats himself endlessly with four note descending and ascending scale intervals, and a lot of the time he and the band were too high to make much sense.
Granted, I weight my ratings in the following order:
1. improvisational fluidity and melodicism
2. technical ability
3. multi-style integration/versatility
A lot of the rock/blues gods are one-trick ponies, staying in one dominant mode and repeating licks. Some people who catch a lot of guff - Frampton and Mayer for instance, are really fluid and melodic improvisers. But if you want a (incomplete?) list of people who do all three-
- Guthrie Govan
- Larry Carlton
- Pat Metheny (we could debate how far-ranging his styles are, I know, but the synth and prepped guitar is a pretty good flex)
- Andrew Synowiec
Heroes that have great technique and improvisation but stay mostly in fairly narrow stylistic lanes (some of them invented their stylistic lanes, tho)
- David Gilmour
- Jimi Hendrix
- Pat Martino
- George Benson
- Joe Pass
- Peter Frampton
- John Mayer
- Tommy Emmanuel
- Mike Stern
- Eddie Van Halen
Then there are the speed/shred guys who seem like mostly technique, without melodic improvisation or style versatility to me, e.g.:
- Steve Vai
- Joe Satriani
- Al Dimeola
Here's Guthrie imitating a bunch of guitar gods in rapid succession:
