12-567 sounds pretty good to my ears. How did you mod the horn? That's about the only flaw I've heard so far.

I'm kicking myself for not keeping notes on what I did to change the horn, as it has been quite a while since I did it. IIRC, someone pointed-out where this info was in the (extremely comprehensive and lengthy) Zimo manual. Even then, it took quite a bit of searching to find it. I'll see if I can find that info again. Incidentally, I don't use Zimo editing software and only make changes via CV's.
