hey there, first time poster, long time drive-by reader... I've been rocking a "Sunn" (Fender) 300T for a couple years now with "Sunn" 410H cabinet - acquired from different sources. The Tweeter did not work when I purchased the 410H.. And so following the 410H manual I replaced the fuse/lamp - no dice. Then a few months later I replaced the horn, and still nothing. I've been content with my rig as is, but if there is more tonal flexibility to be had then I want it. Just curious if anyone is experienced / familiar with this. I saw a similar post from 2004 - pretty sure I didn't acquire that cab. I would also appreciate any comments/suggestions/delusions regarding tweeters/horns in general.
