Hey

The reason for him not using his double necked in Wanted is simply because he has a new guitar and wanted to use it.......after all, his double necked will be pretty old by now!!

As for his electric double necked, the reason he played with one live a few times before is because one was a twelve string with a capo on the second fret, the other was a regularly tuned six string only used for the solo. On the HAND tour, Bobby Bandiera played the Have A Nice Day solo so there was no need for richie to use his double neck, the single one did the job.

Hope this helps, anyone else please feel free to correct me if you think i'm wrong (after all i'm not really a guitarist.......lol)
