Jeff runs his guitars into a Mesa-Boogie Mark IV amp head, which powers two Mesa speaker cabinets. Mesa amplifiers first became known when they were adopted by Carlos Santana, who used one to obtain his signature sound. Hand-built, they are used by Paul McCartney, the Rolling Stones, and many other internationally prominent acts.

John plays through Ampeg bass amplifiers. Ampeg amps are renown for being the bass amps of choice during the classic rock era. Here is his Ampeg Portabass 250/2-10 which he uses for practice sessions.

John's Ampeg SVT450 head with 1-15 and 2-10 cabinets...this is the setup he uses in live gigs.

Patrick uses a Fishman Loudbox Performer for amplifying his Taylor acoustic. The Fishman is a powerful acoustic amp--130 watts--in a small package: 19.25" x 15.5" x 11.2" and weighing 35 lbs. The Loudbox has two channels each with 3 Bands of EQ for exceptional tone-shaping capability. Digital Effects include Hall 1 & 2, Chorus, and Plate 1 & 2.

To gain foot-switchable control of vocal effects and harmonies, Patrick uses TC Helicon's VoiceLive digital processing floor unit. The VoiceLive is tremendously flexible, offering up to 4 additional vocal harmonies using scale, chord, and shift-based constructions, a large variety of vocal effects with fine parametric control over each, 99 presets, and 50 pre-programmed song sequences each of which can be up to 30 steps. Says Patrick "Learning how to use the VoiceLive was quite a challenge, a lot of people buy it and then give up and sell it again on eBay, but now I count on it. There's a worldwide forum of users who help each other out getting the most out of the unit."
