I see that last posts in this thread are from 2016 and it's now 2019 and I am all of a sudden experiencing the same problem. I bought my G30 in December of 2016 and it's been great since then. I gets used weekly. Recently it started having the dropout problem. My question is, this. Our bass player just got a G30 a few months ago, so his is a recent version - could it be causing the dropouts with my older G30 - assuming there's a difference in firmware or something else? Thanks in advance for any help!
