Featuring an interesting new take on the usual three-knob EQ section, the Bass and Treble controls use traditional “tone stack” technology, yielding a familiar bright chime based on 50 years of tradition, while the active Mid control provides a more strongly voiced cut/boost function for increased versatility. Increasing the Mid control boosts the frequencies that give an aggressive “D-Style” bite to the sound, while decreasing Mid brings out that familiar clean-60’s Blackface tone.
