Kurt Cobain

Hand-written note with Kurt's settings for the Electro-Harmonix Polychorus, new version of the 1977 Echoflanger, (for Heart-Shaped Box and Radio Friendly Unit Shifter):

Effects:

10). Electro-Harmonix EchoFlanger (32)(40) and Electro-Harmonix PolyChorus (37)(seen at various photographs/concert footage.).

Despite the different names, the Polychorus and Echoflanger had the same internal circuitry. Kurt supposedly only had one EchoFlanger, despite what is said in (32). Kurt used the EchoFlanger on the Brazil shows (source info? Rio perhaps?) and the song "The Priest They Called Him" (found on various bootlegs, etc.). Both pedals were taken on the "In Utero" tour.

The EchoFlanger sometimes "acted up" and Earnie gave Kurt his PolyChorus as a back-up. This PolyChorus was used on "In Utero" for the "Heart-Shaped Box" solo, "Radio Friendly Unit Shifter," and "Scentless Apprentice" (41). Earnie sent out another PolyChorus to Kurt, hoping to get his back, but the "new" one broke and was given to Eric Erlanderson of "Hole" who had it fixed. Earnie did eventually get his PolyChorus back, but not before Kurt marked his settings on it with nail polish and put Velcro on it.

The EchoFlanger was supposed to be used on "Unplugged" but caused too much 60-cycle hum in the control room. Courtney now has Kurt's EchoFlanger (40).
