Front Panel (from left to right)
Input
Plug your guitar in here. Always use a good quality screened guitar lead.
Volume
This controls the overall gain (input volume) of the amplifier's preamp in both the Clean and
Overdrive mode. Turning the control clockwise increases the gain and harmonics.
Clean/Overdrive Toggle Switch
This control allows you to run in the Clean mode or engage another tube gain stage to get higher
gain tones. Notice that there isn't a large jump in perceived volume as you engage the extra gain
stage. This is intentional.
Bass
Controls the amount of low frequency in the preamp. Counterclockwise decreases the amount of
low frequency and turning the control clockwise will increase the low frequencies.
Mid
This control is very important in the shaping of the overall amplifier tone. Full counter-clockwise
will scoop out the midrange frequencies emphasizing the bass and treble frequencies. Pushing
this control clockwise will increase the amount of midrange in the amplifier. It is normal that this
control seems to increase the overall volume level of the amplifier when in the more extreme
(past noon) settings.
Treble
This control manages the treble frequencies. Turning to the right , past noon will brighten the
signal adding more high frequencies and attack. This control is designed so that generally
keeping it at the noon position is a good starting point. Turning this control counter-clockwise
can also allow in more midrange frequencies.
Presence
The Presence knob is a global control of the higher mid and treble frequencies after the Return
stage of your amplifier. Use it to set the overall brightness of your amplifier.
Master 1
The Cub amplifier has two independent master volume controls. These control the overall
amplitude and volume of the amplifier. Use the Gain control to regulate the amount of overdrive
and control the output level / amplitude with the Master. You can set one Master for rhythm
volume and the other for lead solo volumes. This is a footswitchable function.
Master 1 and Master Toggle Switch
You can toggle and activate either of the two Master volume controls using this toggle switch.
(This is bypassed when the footswitch is engaged)
Master 2
The Cub amplifier has two independent master volume controls. Like Master 1, this controls the
overall amplitude and volume of the amplifier. Use the Volume control to regulate the amount of
gain or distortion and control the amplitude with the Master. You can set one Master for rhythm
volume and the other for lead solo volumes. This is a footswitchable function.
Reverb
Controls the wet/dry ratio between the unaffected dry signal and the wet, effected reverb signal.
Turning this control to full counterclockwise will remove the reverb from the circuit. Turning the
control clockwise will gradually increase the amount of reverb in the circuit. Set it where you feel
it suits your playing style and circumstances best.
