I just bought a BBN5A, and I'm looking for advise, experience, and/or opinions about setting the 3 position midrange control settings. The mid control is a three position switch; the three positions are are flat, EQ1 and EQ2. The control cavity has pots for EQ1 Center Point (Hi-Lo), EQ2 Center Point (Hi-Lo), and EQ2 Boost/Cut. Is EQ1 boost or cut? I'm just digging in, and any info about setting this mid control would be most appreciated. Thanks!
