Although I own a plethora of instruments and assorted gear I have 3 different rigs for most of the gigs I play. The format of the gig determines which rig I will use.
Jazz & Blues
Guitar: Highly modified Paul Reed Smith McCarty model strung with a stock set of GHS Boomers. I generally us a set of .011's and replace the .011 wirth a .012.
Amp: Roland Jazz Chorus 120. I use the onboard effects. Generally no other effects.
Occasionally I'll play a solo instrumental jazz gig where I'm strictly background - ambiance for fine dining or an art show or a reception of some kind. In that situation I'll use my Gibson 175 and a Polytone Baby Brute amp.
2 signal chains: the guitar goes into a Cry-Baby Wah-Wah, then to a Boss Rotery Ensemble, then to an A/B Box.
Lead Side: Marshall Guv'nor Plus Distortion > Boss Chorus Ensemble > one side of Boss Stereo Volume Pedal > Boss DD-3 Digital Delay > Boss RV-5 Digital Delay > Left Channel of JC-120.
Rythmn Side: MXR Distortion II > other side of Boss Stereo Volume Pedal > right side of JC-120. I use the onboard effects: Spring Reverb, Stereo Chorus and Tremelo.
Guitar: Martin MC28 or a Martin GPCPA3 strung with light-gauge Martin Phosphor Bronze.
Pedal Board: Guitar goes to a Korg KVP-001 Volume Pedal > Boss 7-Band EQ > Digitech JamMan Looper > Boss 7-band EQ > I rely on the PA for reverb and delay effects.
