Last night it finally happened. While g string poppin' on my Carvin during 'brickhouse' at ear-splitting volume the smell of buring paper and electronics filled the rehearsal shed before the end of the song. The Foster compression horn in my Avatar 212 is toast. I can't even turn the attentuator in back - must have melted something. Anyway, shouldn't be to hard to replace. All a part of rock n roll. Actually, I was relieved the burning wasn't coming from my QSC!!! My question is, can I disconnect the fried horn and use the cab 'as is' until I replace it. Will taking the horn out of the circuit change the cab's impedence in some negative way? I want to take it out so I don't start a fire in there. Also, if you have some advice on a replacement horn that would be cool.
