3 Marshall 1960 4x12s with Celestion greenbacks, 3 Caliber .50+ heads:
Keenan: They're all modded. I have a great guy in North Carolina who does mods. He's put power soaks in some of them, taken care of a lot of grounding issues, and also made it so that of my pedals all have individual loops for them so that nothing runs through anything else. It really seems to make a big difference.
Keenan: I have an old green Ibanez Tube Screamer distortion, an MXR 6-band EQ like Dimebag Darrell had, an MXR Phase 90 phaser, Boss Flanger, Electro-Harmonix Small Stone phaser, an old Boss digital delay, and a Tsunami chorus. That's about it onstage. I have a bunch of crap at home that I don't take on the road. I have some crazy old phaser that's a two-station phaser which I think is like the one Robin Trower used way back in the day. It's got two different phase settings on one pedal, so you can change the speed on each setting, which is cool. I've got this weird little Randy Rhoads-sounding box that was made by a company that went out of business. I wish I could remember the name of it. The dude's father made all these pedals and he gave them to me at a show. They're from the '60s and one of them sounds just like Randy Rhoads' doubling effect. I don't know what it is. If you stop playing, it makes a lot of noise, but if you're playing something like the intro to "Crazy Train," you're right on it. I've used that in the studio. I also have a Rocktron Intellifex multieffects processor in my rack that has this great octave setting. It's the only octave effect I've ever found that you can play chords on and it never wavers, and it's the only octave effect I've ever heard that sounds legitimate. I've also got a Sony wireless system, which is really good.
All my pedals and effects run through individual effects loops in the amp, and I use a midi controller pedal on the stage so I can step on one program that turns on the chorus and the MXR Phase 90, or whatever individual series I want on each loop.
All you can see onstage is the Marshall 4x12s. Most of them are obviously unloaded. It's funny watching the crew take it apart. The loaded cabs are the top ones.
