HI INPUT:
Controls the high frequency material in the power amplifier.
Adjusts the overall volume of the overdrive channel
Adjusts the input level of the overdrive channel.
Allows activation of the overdrive section from the front panel.
Controls the amount of valve overdrive. The overdrive is applied to the circuit just prior to the gain
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.
This input provides maximum gain from the instrument to the pre amp. It is extremely useful for
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.

POWER CONNECTOR:
POWER FUSE:
This is where the mains cable attaches.
This fuse protects the AC power of the overall amplifier. Use ONLY the correct size and rating
of fuse as specified on the panel. If a fuse blows or fails and a replacement of the same size and rating is installed
and it in turn blows, the amplifier has suffered a malfunction internally and needs immediate service from a
qualified technician DO NOT TRY USING A FUSE OF HIGHER RATING.
