I think you may be thinking of Mel from PBX. He disappeared a few yonks ago and many guys weren't happy.
Anyway it's funny I happen to see OP post....Josh asked me about that marker mod a while back when his project was in an earlier phase. More often than not we're interested in helping each other out, or at least in this case that was my position since it was just a one-off modification I temporarily installed in that particular Impulse. I won't fill in any details since I don't really know his timetable from back then (or now, really).
Needless to say, it's refreshing to work in a side of the industry that simply wants to make parts rather than complain, steal, and litigate each other out of sanity.
