Hi,

In Mark IV's manual, HARMONICS / MID GAIN SWITCH section :

"To duplicate the sounds of our fabled MARK II-C, switches should be set for HARMONICS and TRIODE, with the PRESENCE controls pulled out. This produces a great balance between punch, smoothness and rich overtones to deliver a guitar voice that’s truly classic !"

Earlier :

"Most noticeable is the big increase in gain and sustain when MID GAIN is selected. This added gain is focused in the mid-range “punch” region and is most noticeable when the LEAD DRIVE control is set very low - at the “threshold of distortion” point discussed earlier. Using this low setting with the MID GAIN on (switch in the down position) produces a punchier, fatter blues sound, especially when used with Pentode and Simul-Class."

My question : is the MID GAIN switch position a ++ mod for the Mark IV ?


Thanks
