Dunlop XP Series Expression Pedal for Kemper

The Dunlop XP Series Expression Pedal for Kemper is an expression pedal built to pair with the Kemper Profiler. Dunlop describes it as "an expression pedal perfectly matched to the device's response," meaning the pedal's sweep is calibrated to how the Profiler reads expression data, so what your foot does is what the unit hears¹.

For a player, that covers the two jobs an expression pedal does on a modeler: continuous control of a parameter such as volume or a wah effect, and on/off switching of effects, which the Kemper version handles with a built-in toe switch¹.

What it does and how it is controlled

The pedal has two controls under your foot. The rocker gives the continuous sweep, and Dunlop says "the sweep action is smooth with accurate tracking from heel to toe," which matters for effects like volume swells or wah where uneven tracking is audible¹.

The toe switch is the second control. Pressing the pedal forward past the sweep engages it, and per Dunlop "the toe switch allows effects with on/off modes to be engaged and disengaged"¹. On the Kemper, that means you can, for example, switch an effect block in a rig on or off from the same pedal you are using for expression, without a separate footswitch.

The same two-part design appears across the XP Series. On the version for the TMP, Dunlop describes the toe switch as letting you "turn FX blocks on and off without interrupting the flow of your performance," and notes the sweep is "smooth and even"³.

Build

The pedal's rocker and base are all metal. Dunlop's wording is that "the all-metal rocker and base ensure high performance and road readiness," positioning it as a pedal that can take being on a board and gigged¹. Dunlop's product page for the pedal carries a Warranty Information section, so warranty coverage is available through the maker¹.

The other XP Series versions

Dunlop builds the XP Series as a family of expression pedals, each calibrated for a specific modeler's expression input rather than sold as one universal pedal. The versions Dunlop lists are⁴¹²:

The Line 6 version is described by Dunlop as having "smooth, accurate heel-to-toe tracking, calibrated to match every Line 6 expression input," and as "matched to the exact response of all Line 6 products with an expression input"⁴. The Helix version is designed to meet the exact specifications of Helix modelers that support expression and toe switch functionality². The TMP version controls parameters such as volume and the wah effect and requires one TRS cable and one standard instrument cable³.

Dunlop also makes more general-purpose foot controls outside the XP Series, including the DVP4, the DVP3 Volume (X), and the Volume (X)8 Volume & Expression Pedal, which sits alongside the Volume (X)8 Pedal in that range.
