Dave Grohl’s Electro-Harmonix Deluxe Memory Man Analog Chorus/Echo/Delay

Dave mentioned using this effect on Foo Fighter’s 1999 album There’s Nothing Left to Lose.

The main riff [on Headwires] is an Explorer playing through the Memory Man and the Vox, and the harmonics were done with the same setup. The choruses are the Duo Jet running through a Rat and the Vox. The high, picking part in the middle eight is an SG through the Memory Man.
