First post so here goes. Got the Krank Rev Jr Pro 20 head last week but I'm wondering if something could be wrong with the amp. When the FX Boost button is engaged the volume is loud and going strong. But when I turn off the FX boost the volume is almost gone completely. I have to turn the amp up to 10 to get the volume back to where it was at 1 with the boost engaged. Even then the tone sounds more fuzzy than with the boost engaged. Anyone else with the amp have the same problem? Emailed KRANK yesterday and haven't heard back from them yet so I figured I try here. thx
