DeLeo's usual live rig while with Stone Temple Pilots consists of an Alembic F1X preamp, a QSC MX1500 poweramp, three Eden 2x12 cabinets and three Eden 4x10 cabinets. One 2x12 and one 4x10 cab are placed on either side of the drum riser, and the third stack is placed on DeLeo's side of the stage and kept in reserve as a backup. He mostly uses Marshall and Fender amplification, but has been seen using vintage Ampeg amps and basses as well.
