Jeff Irwin (Will Haven)

In a YouTube interview with The Bogcast (Ep149), at 1:23:45, Jeff Irwin (Will Haven) states: "Initially I was playing ESP for a long time because Stephen (Carpenter of Deftones) hooked me up with ESP, so I was kind of an artist on ESP for awhile but I initially started playing ESP when they had like the neck throughs, they were the M-II's and they were just made so good they sounded so killer, but then they went to the LTD's and LTD's were not to me weren't as good as the originals. They were like I think just a little cheaper wood or something, they just weren't as heavy and like just as solid as the originals." This confirms that Jeff Irwin used the ESP M-II Deluxe.

In a YouTube interview on The Bogcast, Jeff Irwin of Will Haven confirmed at 1:24:16 that he uses a Gibson SG Special. He stated: "So I went and bought an SG, SG Special because we were touring a lot and ESP is really expensive and we didn't have like road cases and shit so my guitar would just get hammered like every time I go on tour, then my beautiful ESP was just getting-those guitars are very beautiful guitars, I'm like this shits getting fucked up. So I went and bought an SG Special, I was like well if I take that and break it I don't care you know like it was 500 bucks and it still sounds decent."
