David Lynch - Sound Design & Boss Pedals:
"Another favorite is the OC-2 Octave, which they deliberately try to confuse with dirty tones so that it struggles to grab the note, which results in what Neff describes as a "broken up, jarring effect."
"I remember Jocelyn took a glass bowl and made a ringing sound going round the rim with a wetted finger, which we then recorded onto the 24-track and vari-speeded to make these really eerie chords. I printed many tracks of the bowl at various different pitches, and by moving faders on the console I could change the chord, a little bit like drawbars on an organ. The way we were able to accurately tune it was with the BOSS tuner."
