Firstly thanks for a great forum, newbie here! I worked at the NEC arena in 1991 on the AC/DC Razors Edge tour and was lucky to have back stage entry. Met the band and had a laff and checked out Angus's rack of 6 SG's They were all late 60's and early 70's but I didn't have the common sense to ask him about them as I had hung my guitars up 2 years earlier. Sis have his used picks and strings tho (strings I lost :-(...don't ask!) I grew up playing to early DC and got every riff and song of the 70's note for note but gotta say Solo Dallas....YOU ROCK mate!! If I had the money then for the gear you probably would have been me! lol Great work on the info my friend!
