About a month ago my POD worked fine, I put it away and left it untouched for a month until now. Suddenly the input is extremely weak, even at +12dB and at maximum master volume. Barely anything, and what is there isn't an accurate representation of the preset.

I thought this may be simply be an output problem, but recording via USB to a computer still picks up the same sound. Playing a song from my computer through the POD as an interface works, but seems to be much quieter than it should be.

I have reflashed my POD and updated all firmware.

Could someone please tell me where the problem lies?
