Stone Temple Pilots' debut album "Core" was recorded with a Jazz-type bass prototype version of his Schecter Model-T bass, a G&L L2000, and an Ampeg SVT amplifier with an 8x10 cabinet. "Purple", their second album, was recorded with his live rig. DeLeo's usual studio rig for most of "Tiny Music... Songs from the Vatican Gift Shop", all of "No. 4", and all of "Shangri-La-Dee-Da", all by Stone Temple Pilots, was more complicated; he split his signal, bi-amping it to a '67 50-watt Marshall Plexi guitar head with '69 Marshall keyboard 8x10 cabinet, and a '59 Fender Bassman amplifier with a custom 1x15 cabinet. This configuration, which DeLeo noted in a "Bass Player Magazine" article as being an idea he lifted from Chris Squire of Yes, allowed him to use distorted and clean sounds simultaneously and produce more workable sounds on tape by blending the signals to taste.
