Another thing that was happening brie I got it here is that the solo bossy would stay on when engaged with the footswitch. You would have to turn the amp iff to reset it. I'm also noticing that when I'm testing the ground on the fx loop jack sleeves to the pt ground it will sometimes show continuity and other times not. Also the channel switching Jacks sleeve all test continuity to each other but not to any of the other Jack's on the back. But the effects please send and return in speaker output Jack sleeves all test continuity to ground into each other.
