Got to finally try the Tribute out yesterday, and I was pretty impressed. It took me a few minutes to dope out the few electronic configurations that I found useful(not all 18 are to my taste ) Though I did find it interesting that even in the so called "passive" mode, the middle knob still acts as a treble knob, and the rear knob as a bass knob. How does that pan out? I figured, wrongly so apparently, that one of the knobs simply became a traditional passive tone knob. However, I found that not to be the case. The active setting seemed to act as a thick volume boost to the tones you get on the passive setting. Anyhow, my question...how does that work with a passive electronic setting, and still use treble and bass controls?
