Yep, these videos were recorded in his studio. Trev has been a member here in the past, I think he has built at least 5 kits.
From the first video, the EVH Franken Strat, Two LP's, Double Necker, and the Cracked mirror IC-1 are all kits.
A little later in the video, there is a green Tele he built for his daughter which won him GOTM.
Behind the Tele is his latest purchase, a Richie Sambora Signature Strat. He also has a Black Kramer, and EVH Kramer hanging there. The black Kramer is his workhorse guitar.
