"Robertson is a full-time musician who splits his time between studio work and filling in on live dates. He says, ""I do a lot of sound effects like airplanes and violin tones, car chases, little stuff like that."" He uses a Korg Tone Works AX3000, Ibanez DE-7, Electro-Harmonix Pulsar, Modtone Stutterkill, Line 6 DL4, Boss TU-2, Biyang Phaser, and a Snarling Dog Bass Wah (""cause I like the lows""), all run through a Hughes & Kettner Redbox run straight into the soundboard or his amp rig."
