noahgolden 0 Posted February 18, 2015 I recently bought this amp, and have it paired only with the POD HD500X. Suddenly, Channel B has lost its 'oomph'. Identical knob/topology settings b/w Ch.A & B yields a pronounced difference in volume and low end, with B sounding 'tinny'. This is universal, guitar direct or Line6 Link. Tube problem? Other?

Brazzy 440 Posted February 18, 2015 You better check with Line 6 to see if your amp is one of those that need warrany work. It's important. I just had it done with mine and it's better than it was when it was new.
