DRIVE SWITCH
Allows activation of the overdrive section from the front panel.
DRIVE:
Controls the amount of valve overdrive. The overdrive is applied to the circuit just prior to the gain
20
control. The drive is engaged only when the drive switch (19) is on. The drive may be operated by the switch or
remotely by the footswitch (FS4) connected on the rear panel.
HI INPUT:
This input provides maximum gain from the instrument to the pre amp. It is extremely useful for
1b
guitars with single coiled or low gain humbucker type pickups. Use of high gain pickups in this input may drive
the pre amp to severely, causing a "mushy" output.
