The Rocktron Hex Expression/Volume Pedal is a single rocker pedal with two jobs: it works as a volume pedal in your signal chain, and it works as an expression pedal for a MIDI footcontroller or another MIDI-controllable device. Rocktron describes it as a multi-function, high-impedance (250K ohm) pedal, and positions it as its own affordable yet professional take on the format1.
What it does
As a volume pedal, the Hex uses its input and output jacks to function as a standard volume pedal: the input jack takes the usual volume pedal input, and the output jack accepts a standard guitar cable and plugs into the next effect in your chain or straight into a guitar amplifier's input. Rocktron describes the volume transitions as smooth in this role1.
As an expression pedal, the expression jack accepts a 1/4 inch stereo RTS cable and lets you plug into the expression port on a MIDI footcontroller or a MIDI-controllable device. Rocktron designed the pedal so the expression connection uses a simple stereo to stereo cable, which the company says minimizes cable use on stage1.
Rocker tension adjustment
One control sets the feel of the pedal: an adjustable rocker tension screw lets you adjust the pedal action for a lighter or heavier "touch". If you play fast volume swells you can set it lighter; if you want the rocker to stay where you put it, set it heavier1.

Questions
Can the Rocktron Hex be used as a volume pedal and an expression pedal?
Yes. Rocktron describes the Hex as a multi-function pedal that can be used both ways. Wire it with the input and output jacks and it works as a standard volume pedal in your signal chain. Plug a 1/4 inch stereo RTS cable into its expression jack and it can control the expression port of a MIDI footcontroller or another MIDI controllable device.
What impedance does the Rocktron Hex have?
The Hex is a high-impedance pedal rated at 250K ohm, according to Rocktron's product page. A high impedance like this is intended to sit in a guitar signal path without loading the pickup the way a low-impedance volume control can.
What cable does the Rocktron Hex use for expression control?
The expression jack accepts a 1/4 inch stereo RTS cable. Rocktron designed the pedal so a simple stereo to stereo cable handles the expression connection, which keeps the amount of cable on stage to a minimum when you run it to a MIDI footcontroller's expression port.
Can I adjust how heavy the Rocktron Hex feels?
Yes. An adjustable rocker tension screw lets you set the pedal action for a lighter or heavier touch, so you can match the feel of the rocker to how you play volume swells or expression moves.
Where can I download the Rocktron Hex manual?
Rocktron's product page for the Hex Expression/Volume Pedal carries a Download Manual link, so the manual is available directly from the maker's page for the pedal.
