‘Hi’ stands for high gain. This input is designed for the connection of low output level guitars making it well suited
for guitars with single coiled or low gain humbucker type pickups. Use of high gain pickups in this input may drive the preamp
too hard causing a "mushy" sound. Only use good quality guitar cable.
Lo’ stands for low gain. This input is attenuated down approximately 50% from the Hi input and is designed for
high output level guitars. It is useful in obtaining output that is "tight" not "mushy" from high gain humbucker type pickups
Also use this input for the cleanest full range sound with extended low end response. Only use good quality guitar cable.
Sets how loud the clean channel is. Try cranking it up a little to drive the power tubes harder for that real
retro sound and feel that only a quality tube amplifier can deliver. Now use your guitar volume to control the amount of
distortion. (Wind it up for distortion back it off a little for clean)
Adds brightness and life to the treble frequencies of your guitar when on the clean channel. Adds edge and picking
emphasis when on the drive channel. The switch has more effect at low Clean Volume/Drive control settings. Use in
conjunction with the Treble and Tone controls for optimum performance. Switch up to enable.
Sets the level of tube preamplifier drive or how dirty your sound is. This control should be used in conjunction with
the Drive Volume (6) Setting low levels of gain with high levels of volume will give a clean preamplifier sound with tube output
stage overdrive. Setting a medium drive level and medium Drive Volume will give a nice crisp bluesy lead tone, again with the
