Well, almost all good jazz guitarists have their own "sound" to a great degree, so it's a little hard to recommend someone who necessarily sounds like Metheny or Benson. That said, however, you should check out the following electric jazz guitar greats, whose "sound" should probably appeal to you:
1. Tal Farlow
2. Barney Kessel
3. Kenny Burrell
4. Wes Montgomery
5. Grant Green
6. Pat Martino
7. Bill Frisell
8. Larry Corell
9. Herb Ellis
10. John Abercrombie
