He seems to use custom 7 and 8 string ibanez guitars. I'm sure these are ridiculously expensive. From what I've seen, it looks like he keeps the treble strings of his guitars taped off, since he doesn't use them and he doesn't want them to give unnecessary feedback.
Here's a list of amps and effects he uses:
* Amplifiers and Effects used Live:
o Line 6 Vetta II Head Units
o 33 MIDI Breath Controller (built by Johan Haake)
o Clavia Nord G2 Engine
o Digitech Delay Pedal
o 2 Unknown Pedals (probably MIDI controllers that control parameters of the Vetta Head Units)
o T.C. Electronics Pre-Amp
* Other Amplifiers and Effects used:
o Marshall Valvestate 8200
o Mesa/Boogie .50 Caliber+
o Mesa Engineering Dual-Rectifier
o Marshall JCM800
o Marshall 1960A cab
o Line 6 POD Pro
o Rocktron Juice Extractor
o T.C. Electronics Chorus & Flanger
o Homemade "Les Amp" Head Unit
o Homemade 1x12" Cabinet
o Yamaha Breath Controller
o Volume Unit (Yamaha BC controls amount of volume that the unit will allow through)
o ADA Rackmount Delay
Note that among this list is the Dual Recto
, digitech delay pedal, and Chorus and Flanger. These are all very cool effects.
