Dunlop XP Series Expression Pedal for TMP

The Dunlop XP Series Expression Pedal for TMP is an expression pedal from Dunlop built to be compatible with the Fender Tone Master Pro. Dunlop describes the sweep as smooth and even, matched to the device's response, and the pedal adds a toe switch so a player can turn FX blocks on and off without interrupting the flow of a performance¹.

What it does for a player

An expression pedal lets a player control a parameter of a modeler or multi-effects unit in real time, rocking heel to toe to sweep a volume level, a wah position, a delay mix or anything else the unit assigns to its expression input. The XP Series for TMP is calibrated for the Tone Master Pro's response: Dunlop says "The sweep is smooth and even," so the parameter follows the pedal predictably across its travel¹.

The toe switch is the second control. According to Dunlop, "the toe switch allows you to turn FX blocks on and off without interrupting the flow of your performance"¹. In practice, that means the pedal handles two jobs at once: the rocker sweeps a parameter while a firm press forward with the toe brings effects blocks in or out, so both hands stay on the guitar.

Build and enclosure

Dunlop describes the pedal as having an all-metal rocker and base, which the company says "ensure high performance and road readiness"¹. The same all-metal construction is used across the XP Series, including the XP Series Expression Pedal for Kemper².

Cables and connections

The pedal connects to the Tone Master Pro with two cables. Dunlop's product page states: "Requires one TRS cable and one standard instrument cable"¹. A TRS (tip-ring-sleeve) cable is the standard connection for expression inputs on modelers, carrying the pedal's sweep signal; the standard instrument cable handles the toe switch connection. Neither cable is a special or proprietary part, which keeps replacements simple on a gig.

How it compares in the XP Series

Dunlop makes the XP Series as a family of expression pedals, each version matched to a particular modeler's expression input³²:

The idea across the range is the same: rather than one general-purpose pedal, each version is calibrated to the exact response of the device it is sold for. For the Line 6 version, Dunlop describes "Smooth, accurate heel-to-toe tracking, calibrated to match every Line 6 expression input"³, and the Kemper version is described as "an expression pedal perfectly matched to the device's response"². The TMP version applies that approach to the Fender Tone Master Pro.
