Hendrix is well known for his unique tone. There's a famous quote about his music being 'like listening to heavy metal falling from the sky'. Often attributed to the first coinage of the term 'heavy metal' in music (
but it's not actually the first usage). Hendrix, again, has a lot of timbre expression in his fingers and his choice of distortion and tone - a lot of it can be heard in Little Wing, including harmonics, scrapes, double stops, doodly-doos, :

Another popular component of Hendrix is the wah wah pedal. The opening to Voodoo child has a notable tone to it. And again note how the expression of the wah wah pedal is being used on the
attack and then a bit like a vibrato (and along side an actual vibrato) in the sustain. Wah wah pedals basically change the ratios of tones, favoring low end tone when it's bottomed out and high end tone when it's topped out.

Sevie Ray Vaughn reproduced a lot of Hendrix style and did excellent covers of both of the above as well as developed a sound of his own that put a southern twist on the Hendrix sound.
Perhaps my favorite song by Hendrix is All Along The Watch Tower. Originally written by Bob Dylan, but Dylan - a great song writer - is not a God of Trimbre. He probably shat himself when he heard Hendrix's version.

In terms of both vocals and guitar work, Hendrix dominates the timbre of these two songs (also way more interesting melodic phrasing in the solos).
