Since his work in Steel Panther, Parrish has been endorsed by Kramer Guitars. He plays Kramer Pacer guitars into EVH 5150 III 100 watt amplifiers which go through EVH Cabs. He runs his Kramer Pacer to his amp through a Line 6 G90 Wireless Relay system. For pedals, he is currently using a Boss TU-3 Tuner, a Boss Turbo Distortion, and an MXR Carbon Copy Analog Delay Pedal - all powered by a Voodoo Labs Pedal Power. In the past, he used Marshall JCM 2000 (both TSL and DSL) amps, and both Peavey 5150 and Triple X amplifiers. He uses custom printed Tortex TIII 1.14mm picks.
The Kramer Pacers Satchel uses are made out of USA manufactured parts rather than off the shelf Kramer Pacer guitars manufactured in Korea and Indonesia. The most noticeable difference is the bubinga skunk stripe on the back of the necks on all of his guitars. He currently uses a Seymour Duncan JB TB-4 pickup in the bridge, and a Seymour Duncan 59' in the neck, and an original Floyd Rose tremolo with an EVH D-Tuna is fitted to all his guitars. He uses D-Addario EXL Super Light (.09 -.42) gauge strings tuned a half-step down to E flat(Eb).
