What mine amp does: operates fine for one hour, or ten, then suddenly puts out white noise, like an AM radio that's not tuned to a station. This has happened indoors and outdoors, in heat and cool, and medium and low volumes, even with the amp just idling with a guitar plugged in but not being played. When the noise happens it's noticeable louder than the music that preceded it. Once the noise pops up, it stays there regardless of the volume settings of channels 1,2,3. When the noise is there, it goes up and down with the master volume. I have seen the noise go up and down with the master level for Effects 1 (not channel 1), and it may have also done that with Effects 2 but can't remember. Rebooting cures it, but the problem comes back and it comes back faster than it did the first time.
Sigh. I've bought used gear for decades, this was my first time buying a new piece of fairly expensive gear. I really wanted to like it. But about a year after I got it, it would just suddenly cut off on me, no sound, and not driven that loud either. It was ~2 weeks out of warranty but I talked to their very helpful technician, then Carvin fixed it for the cost of shipping ($14). But several months later this problem rose up. Spent 45 minutes yesterday just to talk to a sales guy who recommended sending it in for repair or trading it in to get 30% off a new one. I'll see if I can get hold of the technician today. But I am pretty disappointed with Carvin, over $500 and I hardly got a few gigs out of this amp. When it works it's a great, but cutting out or spitting out white noise, can't risk it on a gig.
Thanks all,
-Steve
