Welcome Rich, a Jnr, either SG or LP with P90 is something I would like to build one day.....just have to obtain royal assent first as I have used up all my forgiveness tokens for the time being.
Whilst an EX looks a bit 'out there' and in your face they are surprisingly comfortable and easy to play. Saw a YT video on Garry Moore a few weeks back and never knew he played one. He specifically mentioned how good they were for playing the blues on middle switch position with both pickups. Heck, even Keith Urban plays one live so it is not just Metallica, etc who use them as seems to be the stereotype.
