Unfortunately I've experienced some trouble with the internal mic recently, there's loud pops and crackling sounds coming from the soundhole pickup. I can avoid it by playing extremly gently, but as soon I hit the strings with a tiny bit more force this noise comes through. It also leaks through to the other mic, so whether I turn the volume down on the second mic or not, it doesn't make any difference.
Are there any others in here who've experienced the same problem, and what should I do about it? I've had the mic exchanged for a new one but it didn't help. The connections are correctly plugged in to the pickup system. Maybe I could open that box and take a look inside, but I don't own any soldering equipment myself so maybe there's not much I could do about it?
