Dunlop Volume (X) DVP3. great for volume pedal and more then great for expression pedal (Marcin uses it with his Kemper Amp).
Kemper Profiler love it for any guitar/bass tracking and reamping. great product that still evaluate, not just been selling as mkII, mkIII version.
Monster® Studio Pro 2000 Instrument Cable. Our favourite to record guitars in studio.
Ibanez UV7 BK "greendot". Steve Vai signature guitar. Marcin has 1994 (so last year production one with upgraded tremolo to LoProEdge7 and DiMarzio BlazeII) dated UV7BK that is by his words "thousands light years above actual UV70P".
