hello!! my Mesa 400+ just came in, i will post some photos and tell you how it works with my SWR Goliath III and traben 5-string bass. Now some more questions, thank you, if somebody could answer.. 1. Are the two inputs 2 different preamps with different tone or is their only difference that one is active and one is passive? if they are different in tone, would it be able to use them both by buying such a footswitsch, what will be the right for it? Line Sector? 2. What does this mean (according to the mesa website) Pull Shift Bass & Treble Controls (Standard Mid Control). "PULL SHIFT"? thank you!
