re: Your favorite guitar sounds (example)

The John Cipploina sound. Per Wikipedia:
Cipollina had a unique guitar sound, mixing solid state and valve amplifiers as early as 1965. He is considered one of the fathers of the San Francisco psychedelic rock sound.

"I like the rapid punch of solid-state for the bottom, and the rodent-gnawing distortion of the tubes on top."[2]

To create his distinctive guitar sound, Cipollina developed a one-of-a-kind amplifier stack. His Gibson SG guitars had two pickups, one for bass and one for treble. The bass pickup fed into two Standel bass amps on the bottom of the stack, each equipped with two 15-inch speakers. The treble pickups fed two Fender amps: a Fender Twin Reverb and a Fender Dual Showman that drove six Wurlitzer horns.[3]

Cipollina used a custom foot switch setup to select reverb, tremolo, Maestro Echoplex (the unit mounted on the right of the Twin Reverb), and Standel Modulux (on the left of the twin reverb). 12 volt automotive running lights indicated which effect was being used.

Cipollina also employed a Gibson Maestro Fuzz and Vox wah-wah/volume pedals.
