I bought a Clarus in 2007, it's been gigged hundreds of times and on 2 separate occasions, someone tripped on a cable and jerked it out of the amp. So, broken 1/4" input on Ch 1 and no XLR input on Ch 2. Rick fixed both, no charge and upgraded a couple of components, also no charge. I didn't miss a payday as the amp was fixed and home in a week. Rick Jones is my hero.
