AWESOME THREAD!!!!! I love this one, cuz it sure made me THINK... It was hard for me to differentiate fave "tone" from fave "playing" and fave "players"... So a very, very interesting mindfuck this one ended up being...pardon the language, but that's what it is at least to me...
Hmmmmmmmmmmmmmmmmmmmmmmmmmmmm, favorite TONE!!!! Alright...in no particular order:
Spiders, by System of a Down, specifically at the 2:30 mark, which then goes into a wickedly fx'd tone at about 2:39 and repeats a couple times. Haunting, and it always makes me shiver...
Aeroplane, by the Chilis... Navarro on the 6 gun for a change (even though I love Frusciante's playing, no flames please). Every bit of it - from the sparkling single coil rhythms to the slap funk to the smoothed over solos and wah work. This is a gorgeous tone to my ears.
Diamond Eyes, Deftones. Thick, potent and wickedly rich...love it.
Randy Rhoads, Live - most popular on the
Tribute release - but I heard it back in the day live off the radio and then on bootlegs...his solo that then drives into Suicide Solution. A tone that had me go apeshit for guitar.
Frank Zappa, Watermelon In Easter Hay, the lead throughout the song (FZ) gives me goosebumps. Love it.
Those are 5 of my favorite tones. I've got more, but these were the first five that popped.
Peace,
V.
