I have a Relay G50. The other day I was playing some clean tone stuff and noticed that if I hit a chord and let it ring, the sound started clear but began to fuzz, crackle, and break up as the sustain from the guitar faded. If I roll back on the guitar volume and pick very lightly, everything I play at low volume is distorted and fuzzy. I use a DT-50, so at first I thought it might be related to the tubes, but when I removed the Relay from the signal and used a cable, there was no issue. Definitely a G50 issue. I had the firmware updated by a service tech who sent it out to Line 6 when the cable connection on the transmitter needed to be repaired, so it is the latest firmware to the best of my knowledge. I've tried switching channels, I've tried Lo and Hi power. Any ideas?
Thanks!
