Bypass Stomp:
Activates or bypasses the effect. This can be changed to a momentary bypass via a dip switch in
the back of the pedal if it is desired. This pedal is “True Bypass” via a relay, and is extremely quiet.
Tap Stomp:
Sets tap tempo, always honors the last two stomps.
Lower Toggle:
This switch recalls presets. The right position recalls one preset, the left position recalls a different
preset. The middle position will always reflect wherever the knob positions, toggle positions, and dip switch
positions are currently at. In order to save to the right preset slot, you hold down the right stomp (bypass) for 3
seconds and then hold down both stomp switches simultaneously for another 3 seconds. The LED blinks and your
setting is saved. For the left slot, you do the same thing but hold the left stomp (tap) first. If you recall a preset, and
move a knob, you will notice that the LED above the toggle goes dim. This is to signify that something has changed
on the preset. If you want to save this change in the preset, you will have to save it again.
IN:
¼” mono input jack.
OUT:
¼” mono output jack.
EXP / CV:
¼” TRS jack for expression pedal (parameter selectable via dip switch in the back of the pedal. Tip goes
to wiper, and we recommend Mission expression pedals (EP-1 or EP-25k). Can also be used to for 0-5V Control
Voltage (CV) on tip – the ring should be left floating in this case. There are many expression pedals that work with
Chase Bliss Audio products, the Mission stuff just happens to be what we have here.
TAP / MIDI:
¼” TRS jack. This can be used as a tap input or output with a regular ¼” instrument cable. In
addition, it can be used to interface the pedal with an Empress Effects Midibox. Much more information on this in
the MIDI section of this manual (at the end).
Power & Other Info
: This pedal consumes ~20mA and should be operated with an alkaline 9V battery or a
standard 2.1mm 9V – 18V DC center negative adapter. If you want more output and headroom out of the pedal, we
recommend powering it at 18V. We recommend Voodoo Labs Pedal Power. Input impedance of this device is 1M,
and output impedance is less than 1k.
Expression / CV Control & Dip Switches:
The Volume, Tone, Rate, Depth, and Sway dip switches in the left bank allow you to control parameters via ramping
or an Expression Pedal / CV. Whenever you plug a ¼” in to the EXP / CV jack, the pedal automatically knows that
you will be controlling parameters via expression or CV,
not
ramping.
Direct Control of Waveform with Expression / CV:
If you have something plugged in to the EXP / CV jack, but do
not
have any parameters selected via dip switch, you
are allowed to control the waveform directly. For Gravitas, this equates to an analog “whammy” type of effect. The
range of this effect can be limited by the position of the Depth knob. For a maximum sweep, set the depth knob to
its full clockwise position.
Setting Expression / CV Range:
The range of the expression / CV is controlled by the parameter knob position and the “sweep” dip switch. For
example, if you wanted an expression pedal to control the volume parameter from zero volume to unity gain, you
would make sure the “sweep” dip switch is in the bottom position and set the volume knob at unity gain. If you
need more volume you simply turn the volume knob up slightly. This will increase the maximum range of the
expression pedal. This allows you to control multiple parameters with an expression pedal, but you can fine tune
the range that you want for each parameter.
On the following page is a diagram and explanation of all the dip switches. When you save a preset, all of this
information gets saved. The parameters in
red
below correspond to the ramp function *or* an expression pedal (if
one is plugged in).
