Ok, I got an Avatar B410 with the Foster horn and I run a GK 700RB-II head into it. My question is, has anyone else rewired the horn to be powered by the GK's tweeter amp? The little 50 watt tweeter only amp inside the 700 and 1001RB heads? I'm curious if it's worth doing, and how I would go about doing it, or if I'm just wasting my time. I know a lot of people complain about some hiss from the Foster horn and I'm thinking this might help a bit, but who knows.
