Well my amp had been working perfectly with Fuse for several months....It has never mal-functioned since purchased used two years ago. Installed Fuse two to three months ago. Was seamless and had been working well.
Installed Sonar....it asked one or two questions during the install regarding devices, including the Fender Amp. I answered to the best of my knowledge (which wasn't much) Now, for whatever reason, the amp has gone silent as in "turned off" resistant to factory reset....I'm going to see if I can get it repaired. Maybe it wasn't Sonar. Don't know.
But it seems very coincidental that the amp ceased operation after having installed it.
Thanks for your comments.
