HI INPUT: ‘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 INPUT: ‘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.
Only use good quality guitar cable.
GAIN: Sets the level of tube preamplifier Gain or how dirty your sound is. This control should be used in conjunction with
the Volume control, setting low levels of gain with high levels of volume will give the cleanest preamplifier sound with tube
output stage overdrive at high volume settings. Setting a medium gain level and medium volume will give a nice crisp tone
with just a little break up and warmth, again with the ability to drive the output stage at higher volume settings. Setting a high
level on the gain control and a low setting on the volume will give you a nice blues tone, with the ability to again drive the
output tubes at higher volume settings. Having set the gain and volume controls to your desired sound try backing off your
guitar volume and tone controls for lots of other cool sounds. Good tube amplifiers have the unique ability to produce a
wide range of sounds by using only your guitar controls, playing weight and style.
BRIGHT: Adds brightness and life to the treble frequencies of your guitar when on the clean channel. The switch has more
effect at low Gain Volume control settings. Use in conjunction with the Treble and Tone controls for optimum performance.
BASS, MIDDLE, TREBLE: These are a traditional set of passive tone controls for the clean channel. Passive controls have
the advantage of always sounding musical at any of their settings mainly due to their unique interactive nature. This gives
players a more natural set of tools to create their ideal sound. (Try them all set at midway (5) as a good starting point).
VOLUME: 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.
