Leslie West's Mountain tone in 1970 came from one P-90 in a Les Paul Junior driving Sunn amplifiers. There was no fuzz or distortion pedal in the path.

## Signal chain

**Order evidence — Not applicable.** No floor effects to order.

No pedals are documented in this signal path.

## Reconstruction note

Asked specifically whether a Fuzz Face was used for the classic Sunn-recorded material, West answered no and confirmed the Junior went straight into the amplifier. This snapshot is limited to the early Mountain sound: his later rigs did add distortion, octave, reverse, chorus and delay devices and must not be conflated with this route.
