Hi! I recently bought the AA12, and soundwise it has been awesome, but when I brought it to the rehearsal place and started jamming, I found out an annoying volume drop while changing presets. The silent gap between presets is so huge, it makes the AA12 completely unusable in live situations at the moment. I've installed the latest firmware, and my setup is really simple, no midi included. I found some threads about the same issue, but it seems like there were no solutions to the problem. Are there any fixes for this? Thanks in advance!
