I recently purchased an Acoustic AG60 amp. The first on I received I returned because on of the channels didn't work. The second was excited about, the sound of my guitars and vocals were great. I took it out and did a gig and before the night was over it developed a popping sound kind of like a purr. Has anyone had any experience with this amp or this problem?
Sounds like a connection / cable issue to me.
Did you run the usual suspects in for interrogation?
