Well you know the old saying.I think I know why he didn't model the ADA MP-1, it would have sounded like shit. I had the chance to play one, and I was not impressed. I think the people that used it in the 80's had a massive amount of post processing done in order to make it sound decent. It sounded shrill to me, overly compressed, and noisy as hell!
Opinions are like A$$holes everyone has one and they all stink!
