Yeah, my biggest complaint about the UA-5 here....if you need to go down or up slightly it is a bitch to re-equalize the channels once you got had gotten them perfect. So some sort of switch/knob that had settings to increase or decrease by 1,2,3,4,5 db would be perfect.
Another possible idea would be if the damn level knobs were able to turn them in visible increments(clicks). So if you do adjust each side you know you can just adjust each side by 1 equal click so they'll both be adjusted the same amount. Get what I mean?
