I would like to discuss something that most people here on Ultimate-Guitar seem to overlook, which would be jazz guitarists and overall it seems to be jazz in general.
I wonder why such an influential genre alone that was formed alongside the blues as blues bands may have evolved from early jazz bands, gospel choirs and jug bands has been so overlooked. Although they may not be obviously the same thing and their is a firm differentiation as jazz fused elements of western styles but played in its own form relying on improvisations and overall being a vast and hard to define genre but also growing up alongside the blues and having also been formed in the southern states of America.
Although jazz relies heavily on instruments like the saxophone, cornet, trombone and piano for example the guitar itself has played a crucial role since it was first incorporated into the sound of jazz as blues musicians would sing and use it for accompaniment. Guitarists like Karl Cress, Django Reinhardt, Tal Farlow, and of course Charlie Christian. I just wonder what is it about jazz that doesn't really appeal to most people here, after all the genre alone has yielded so many great guitarists and just because it isn't "hard rock" or as appealing as the so called "rock god" guitarists I think these musicians are greatly underplayed and often times overlooked; they may not make their guitars scream but there is just as intricate, speedy, and meticulous playing going on that is in my eyes just as beautiful and highly professional and for me alone I think the greatest guitar players are mainly jazz guitarists.
Please forgive me if this list isn't actually complete as their are many jazz guitarists that are so great in their own right, I will have to compose this into a top 100 list most likely in the future but I will try to include the ones that are really essential to listen to if you aren't aware of them already and I will try to include highly influential guitarists too.
20. George Benson

8. Grant Green
Green's primary influences were saxophonists, particularly Charlie Parker, and his approach was therefore almost exclusively linear rather than chordal. He would perform various kinds of soul infused jazz with smooth grooves and overall is a terribly underrated guitarist in general.
7. Allan Holdsworth
Holdsworth would utilize a vast array of complex chord progressions and intricate solo to give him a distinct and unmatched sound. He would use his unique legato soloing technique because his original intentions were to in fact play a saxophone but he successfully created his own unique and complex sound of diminished, augmented, whole tone, chromatic and altered scales giving that "off" and unpredictable genius sound.

4. Joe Pass
Joe Pass would use walking basslines, melodic counterpoint during improvisation, use of a chord-melody style of playing and outstanding knowledge of chord inversions and progressions which would open new possibilities towards the jazz genre and he is often thought to be one of the greatest jazz guitarists of the 20th century... Need I say more?

2. Django Reinhardt
Often considered one of guitar players of all time and also the first important European jazz musician, making major contributions to the genre.
