One side was sent to a SansAmp and a chain of vintage analog synthesizers that included a Serge modular system, an Arp 2600 and a Moog Modular system with a Boda frequency shifter. The other side of the signal went into a Watkins Dominator, a small but deadly vintage British combo amp. "The boda thing has octaving, phasing, flanging plus a frequency analyzer and shifter all mixed in," says Erlandson. "So I threw out a lot of plans to use a lot of pedals. Meanwhile, the Watkins provided tons of low end."
