Guitar effects on non-guitar instruments
Instruments other than the guitar that use effects that are traditionally reserved for the guitar, like fuzz, guitar amps, volume and wah pedal. If you want to use bass guitar as examples that's fine also.
Black Sabbath- NIB, The Intro is all Bass Wah
Eddie Van Halen would put an electic piano through a Marshall amp on "And the Cradele Will Rock"
The Beatles "Savoy Truffle" which is one heavily distorted production features a wall of sax sound heavily distorted or fuzzed.
King Crimson "21st Century Schizoid Man", I think also has distorted sax, fuzz bass and vocals
The Beatles would put pianos and harmoniums through their Vox guitar amps "Penny Lane" especially the feedback at the end is from a piano through a guitar amp and "Birthday with tremolo effects
John Cale would put guitar strings on his viola and you hear it on songs like "Venus In Furs" or the screeching sound that you hear on "Heroin"
The Beatles, The Rolling Stones and Soft Machine would put their bass through fuzz boxes.
Sistar Ray? organ through amp
Thanks, I remember reading that "Sister Ray" organ sound was recorded through a Vox amp.
In the Dirty Three, Warren Ellis uses a guitar pickup on his violin.
