According to Yamaha's website, Mazur is a user of Yamaha PAC1511MS Mike Stern signature guitar.

It was on this record and it was for touring up until now. I’m playing new guitars now live. I went to Gibson Canada right when this tour started and they had one of their Trini Lopez reissues. They asked me to try it out so I took it to our rehearsal space and played it and fell in love with it. It still has that great warmth that hollow bodies have, but it has a little more balls than my Starcasters did. And for our band and me being the only guitar player, it fills the sound out so much better. So I am actually playing those now and I’ve never been happier with my tone.

And this guitar is still his main guitar...

According to Radial's website, Mazur uses Radial Switchbone.

I had been running tracks out of Pro Tools and processing them through stomp-boxes but the results were hit and miss. Then I heard about the EXTC 500. So great!! Now the tracks are always at the proper impedance and the whole phase flip for different pedals is genius. I don't see how I lived without it!
