Patrick Simmons

"This 1982 Westwood was built by Simmons’ guitar tech, Joe Vallee. It has been on every Doobies album since 1990."

"For all his amp needs, Simmons rolls with a single Mesa/Boogie Mark V. He uses the various channels to gain up his signal (or become Keith Richards, as he puts it) and depends on tube saturation for distortion. Simmons does have a second Mark V in the rack for backup purposes."

"“Living in Hawaii, I’m more appreciative of its wonderful Hawaiian motif.” This ’22 Gibson L-4 was given to Simmons by a friend for whom he posted bail. Pat Simmons/guitars photos: Nadav Benjamin."

In a video by the Roberto-Venn School of Luthiery, the creation of the Joe Vallee Pat Simmons Custom Koa Guitar is showcased, highlighting its design for Patrick Simmons of The Doobie Brothers.

"This ’62 model was Simmons’ first Fender Stratocaster, and set him down the path as a “Strat guy.”"

The item can be seen 30:04 into this video.

"Handling some of the acoustic songs is this Rick Turner Renaissance. Simmons really enjoys how this one sounds because it's more piano than guitar and it generally sees the stage for “Clear as the Driven Snow.”"

"The acoustic workhorse is this Taylor 712ce that hits the stage for “Black Water.”"

"His pedals out front onstage include a Boss RT-20 Rotary Ensemble, a Boss CH-1 Super Chorus, TC Electronic Flashback Delay, Electro-Harmonix Micro POG, Pedalworx Doobie Double Drive. Simmons has one tuner for electric and another for acoustic: a Boss TU-2 Chromatic Tuner and a Peterson StroboFlip. Everything is powered by a single Voodoo Lab Pedal Power 2 Plus."
