JUPITER JUNIOR FRONT PANEL
[1] INPUT: Input for all types of instruments, e.g. guitars
with single-coil, humbucker or active pickups.
[2] CHANNELS SWITCH: Selects the COOL or the HOT
channel if no external channel switch (e.g. the FS2
footpedal) is connected to the FOOTSWITCH jack [6].
[3] VOLUME: Controls the volume level of the COOL
channel.
[4] GAIN BOOST: Selects Medium Gain for Crunchy
sounds (down) or High Gain for Lead sounds (up), in the
Hot channel.
[5] GAIN: Controls the amount of distortion in the Hot
channel. A cleaner sound is achieved at lower settings (1-
3). At middle settings (3-6) the sound will get more
distorted and harmonically richer. At high settings (6-10)
high-gain overdrive occurs with more sustain and
distortion.
NOTE: High gain settings (GAIN knob "over 5" and Gain
BOOST "on") may cause squealing and/or excessive hum
and noise, due to microphonic guitar pick-ups and
insufficient screening of guitar-circuitry.
[6] VOLUME: Controls the volume level of the HOT
channel.
[7] BASS, MID & TREBLE: Classic (post-distortion)
passive tone controls for both channels.

[8] REVERB: Controls the amount of spring-type reverb
signal mixed with the original dry signal.
[9] DIMMER: This control is a unique feature and controls
the output power of the amp continuously between zero
and full power, without any loss of tone.
It can be used to control the overall volume level of your
amp, but also to create power amp distortion. This power
amp distortion can be created by turning the Dimmer knob
down and turning the channel Volumes [3] [6] over 5.
[10] MAINS SWITCH: Turns AC power On (red LED on)
and Off (red LED off). When the switch is Off the amplifier
is completely shut down.
