Control Voltage
Control voltage input is configured the same way as an expression pedal.
CV Range: 0-3.3V (with over/under-voltage protection)
Tip: 0-3.3V input
Ring: 3.3V output (with current limiting)
Sleeve: ground
The expression input has current limiting in case you use a TS cable, but it is preferable to use a 1/4”
TRS cable with the ring unconnected. We sell a suitable cable at our web site, and the Expert Sleep-
ers ‘floating ring’ cable is another option. Instructions for building your own cable are available on our
Tap Tempo
Uses a normally open momentary switch. Configure it using the web editor.
TRS MIDI
Select
MIDI (TRS) in the web editor to use the control port as a MIDI input. This is a non-standard MIDI
interface, because there is no optocoupler on the input to prevent current loops, but it is used by many
guitar pedals. You will need a converter or a MIDI controller with 1/4" TRS outputs, which are available
from Empress Effects, Disaster Area Designs, and others.
Remote Switch
A remote switch has up to 4 modes of 4 switches that can access presets and pedal functions. It works
with our remote switches, some third-party switches, and is DIY friendly for different control interfac-
es. See our
for infomation on building a compatible switch. Note that the switch uses
parallel resistors, and switches with shorting contacts will not work without an adapter (most tap-tempo
switches and the Roland FS-6, for example).
1, 2, 3, and 4-button switches are supported. The modes and functions accessible will depend on the
number of buttons. A single-button switch can load or save your favorite sound.
To save a preset, hold the corresponding button for two seconds. The right LED will blink green to indi-
cate that the preset has been stored. Presets are also accessible via the
PRESET button and MIDI pro-
gram change messages.
Configuring a Remote Switch:
1. Start with the pedal powered on and nothing plugged into the
CTRL port.
2. Hold the right footswitch while plugging in the remote switch. The right LED will blink yellow 3 times
to indicate it is in
CTRL configuration mode. You can release the right footswitch and begin configu-
ration immediately.
3. Press one of the buttons on the remote switch to select a mode.
4. Hold the right footswitch for 2 seconds to save the configuration. The right LED will blink green to
indicate that the configuration has been saved.
