With the LB-30, has anyone else noticed the "odd" behavior (at least to me) of the volume control with the EQs? For example, if all knobs are turned to the left, turning the Volume to the right does not actually provide volume (yes, I've checked the Mute switch and both Inputs). On the flip side, the actual Volume knob can be all the way to the left, and you can create volume with each of the EQ knobs independently by turning them to the right, albeit with varying frequency responses. Interesting approach, but I was convinced for the first 10 minutes that my brand new amp was either broken, or the power tubes just took hella long to warm up.
No nothing wrong. That's completely normal with a passive tone stack EQ....bit of a different animal if you're used to a "normal" active style EQ.
