ARCADE BUTTONS

JUMP

The Jump button feature lets you quickly skip to presets and 
can be used in conjunction with the preset foot switch to 
create a subset within a bank. If the Jump is active, when you 
hit the PRESET Stomp it will jump to either 0 or 5. For example 
if you are on Preset 6, and the Jump button is lit Blue, hitting 
the Preset Stomp will skip to Preset 0. If you are on Preset 6 
and the Jump button is lit RED, hitting the Preset Stomp will 
skip to Preset 5. This option is saved with each preset. It’s an 
easy way to toggle between 2 presets or create groups inside 
the Bank of any number to allow quick scrolling through your 
favorite settings.

MIDS

The parametric MIds control can be moved before, or after 
the Benson Preamp circuit. If OFF is selected the parametric 
Mids circuit is removed from the signal path and the MIDS and 
FREQ faders are inactive.

Q

This button will affect the MIDS-FREQ faders. It selects the 
“Q” for the parametric Mids control providing three Mids 
resonance settings. Select the LED OFF for a wider hump/
scoop, Blue for more focused, and Red for very narrow.

DIODE

The selectable diode clipping control includes transistor only 
(which is stock for the Benson Preamp) a symmetrical silicon 
setting (think tube squeezer flavor), and an asymmetrical 
germanium setting (like a tone pony flavor).

FUZZ

The fuzz circuit has two modes, a full on wide open Fuzz,  
or a Gated version. It is inserted before the Preamp and 
midrange controls in the circuit of the pedal.

EXPRESSION

While on the T and H pages, faders not selected  
on the E page will reference their Preset settings,  
do not need to be moved, and will not effect audio. 
This allows you to safely audition the core preset
sound while fine tuning the T and H ranges of faders 
selected for expression control.

Finally this expression mode is referred to as Local,  
in that it only effects the preset which you entered 
the Setup Menus from. So you will have 30 presets, 
and 30 expression settings one for each preset.  
Plus one more…

EXPRESSION MENUS

There are three pages in this setup. Page “E” will 
assign which faders expression will control. Page “t” 
will set the position of each fader when expression 
is all the way at the max toe on your treadle (or 5v 
on CV). Page “H” will define the position of each 
fader when the treadle is at full heel position (or 0v 
on CV). When adjusting you can skip to any page 
and modify only that page. No need to do each 
page each time. The settings created or changed 
here will only be saved to the preset when you exit 
and HOLD BYPASS (or send a Midi Save CC). Worth 
noting: we are only setting the faders range, not 
your expression pedals range. There is no need to 
move the expression pedal during any of the setup.

To connect an expression pedal, insert a TRS cable from the expression pedal to the EXP jack on the back of the pedal.  

By default, the expression pedal controls no parameters and will need to be assigned to the sliders. This can also be used  

for 0-5V Control Voltage (CV). When using CV instead of expression, you should use a TRS cable with the ring floating.
