Variax (VDI) --> POD HD500 (Studio/Direct) XLR --> ALTO TS212 (XLR)
I have tried using ground lift on both, not using ground lift on both, using the contour button, tweaking the patch, removing bass from the amp and cab. nothing seems to be working. The only patches that sound good are the ones that are completely clean but even those sound like they have a little too much bass.
