Tone
The Clean channel EQ is a simple single-knob Tone control. This is essentially a variable frequency notch filter
that allows you to dial in a nice clean tone regardless of your playing style and guitar. A little movement on
this knob can make for a big change in sound.
Level
Each channel has a Level control that allows you to dial in the respective channel’s volume. You can also use
this to boost (or cut) the volume of one channel relative to another, such as a solo boost, for example. Note
that the Clean channel naturally needs a bit more Level to balance with the more compressed distortion
channels.
Depending on your power amp sensitivity, these will either be set relatively low, or relatively high. For
example, if you run the Ceres into the effects loop return of a head without a global Master Volume or Loop
Return Level control, the Level knobs will need to be set very low for non-ear bleeding volume. If the amp has
a global Master Volume, as all of our amps do, then start with the Level controls around 12:00 (noon) and
boost/cut from there to balance. Then, use the amp’s Master Volume to adjust your overall volume.
Buttons
When you press the Bypass (left) footswitch button the pedal activates either the Rhythm or Lead
channel. The KSR logo lights Blue for Rhythm and White for Lead. Use the right footswitch button to toggle
between the two distortion channels.
Note that if you press the right button while the pedal's bypassed it will blink the color of the channel you
switched to, but it won't actually change to that channel until you hit the Bypass button again.
You can Mute the pedal by holding the Bypass button for a couple seconds. The logo will start blinking and
you can re-enable the pedal by hitting either button.
External Control Input
Overview
The Control Input jack allows you to change channels and bypass the Ceres from any control-closure output,
such as from a loop switcher or effects processor. This should be a “dry” (relay) contact only, without a
common ground to the audio signal path in order to prevent ground-loop (hum) issues.
Control
The jack is an 1/8” TRS style jack. If the contact closure output is two relays already presented with a TRS jack,
this will likely work with a simple cable to connect the two. If the contact closure output is split between two
TS jacks, a Y-cable to combine these to a TRS connection will be needed.
To operate the pedal remotely, simply connect the Tip to Sleeve to activate the distortion channels. Connect
the Ring to Sleeve to activate the Lead channel. These require latching-style relay control.
Note if you press the pedal buttons the state of the pedal will be overridden from the control input
connections. This is handy if you want to change things up on-the-fly from your programmed presets. As
soon as the external control changes state, it takes over the state of the pedal.
