the knob to the right is a dedicated tweeter volume. the rig sounds really great! i initially purchased it for a roland kit i had. then used it for learning bass. i hadn’t used it for sometime until last week a few buddies and myself from our worship band got together to write some original tunes. our bass player loved it for his p bass and fretless j bass. tried to take it home with him!It honestly looks like something I would have built in college. Looks like a good feature set for the time. What does the knob at the extreme right do? I am also assuming the Bi-amp part is tweeter and woofer since there is no speaker out. But hey man, cool little amp! How does it sound?
that’s when i figured i’d take pics and try again to find answers here.
so far, no solid leads. except a suggestion to open the hood and look around. i’ll do that and keep you all updated. thanks! louie
