I love this amp and use it as a stage monitor, It sounds awesome as a slide guitar amp, but the microphone channel seems to have gone out. With a dynamic mike in channel 2, I get no sound. With a guitar in channel 2, I get nothing. With a condenser mike and the phantom power on I get some vocal, but not anywhere near the volume it used to have. Does it sound like the pre-amp on the channel has gone bad? I have built amp kits in the past, so am handy with a soldering iron, but wonder if I'm on the right track. I asked Fishman to point me in the right direction, but haven't heard from them yet. Thanks.
