It’s all about ESP guitars and cranked Marshalls for one of death metal’s most melodic shredders.
The guitars run into a Sennheiser G3 500 wireless unit. From there, the signal flows to a Boss NS-2 Noise Suppressor that lives on the top of his amp. Within the loop of the NS-2 lives the rest of his pedals: a Dunlop Kirk Hammett KH95 wah, Boss CH-1 Super Chorus (which is always on), and finally a Boss DD-7 Delay. A T-Rex Fuel Tank Junior keeps everything juiced.
Thanks to tech Mikko-Pekka Laine for help with the details.
