OK. I've had a few. Whatever was on an old Warwick Streamer, The Bongo 5HH and a John East Retro. [edit: I did have an 18v EMG thing on a Precision and I think an old Ibanez Musician had actives, but it was a long time ago.)
I'd say the Bongo was the best by a country mile, so long as you didn't abuse it. I'd start off with everything flat and just tweak to accommodate who and where I was playing, but by the end of the night after some excessive twiddling, everything would be ramped up full and it would sound horrific. I'd say the Bongo was the reason I decided to go passive thereafter. (I even posted a thread here at the time asking whether I could pull the active stuff out somehow; it was kinder to just sell it on.)
