Essential Information About the Lehle Dual Expression Pedal
Essential Information About the Lehle Dual Expression Pedal
- Dual Control: two expression outputs to control two devices (or two parameters) from a single pedal.
- Wear-Free Precision: magnetic Hall effect sensor and data generation via digital potentiometers, without a mechanical potentiometer that crackles.
- Wide Compatibility: works with most expression inputs on the market (range 5k to 100k, TS, TRS, or RTS wiring) with switchable and storable polarity.
- USB MIDI: sends MIDI data to a computer to control MIDI-compatible software.

A "Lehle" Approach: Frictionless Expression Designed to Last
The Dual Expression embraces a core Lehle idea: replacing wear-prone parts with contactless measurement. Here, the pedal's travel moves only a magnet, whose distance is precisely read by a calibrated Hall sensor. The result: a smooth feel, stable response over time, and a pedal that remains reliable even under intensive use on stage or in the studio.
In line with the product range, Lehle has also optimized the format: more compact and noticeably lighter, while maintaining robust construction and a comfortable pedal travel underfoot.
Who Is the Lehle Dual Expression For?
If you use a multi-effects unit, a modern amp, an amp simulator, a delay, a reverb, an expression-controllable wah, or a synth, the Dual Expression quickly becomes a central tool on your pedalboard. It suits both musicians who simply want to control volume or effect mix, and experienced guitarists automating multiple parameters live (gain, filter frequency, modulation speed, reverb depth, preset morphing).
Its major advantage also appears in professional contexts: studio, sessions, tours. The precision of control, mechanical stability, and compatibility with various expression standards prevent unpleasant surprises when switching devices or setups.

Questions frequently asked
Is the Lehle Dual Expression compatible with TS, TRS, and RTS?
Both outputs accept TS, TRS, and RTS wiring. The polarity is adjusted via soft-push buttons and can be stored according to the controlled device.
Can this pedal be used with a multi-effects unit or a synthesizer?
This model is suitable for multi-effects, modern amplifiers, amp simulators, expression-controlled effects, and synthesizers. It notably allows controlling volume, mix, gain, a filter, or modulation parameters.
How does the end-of-travel switch mode work?
One output can be configured as a momentary or latching switch when the pedal reaches the toe position. This function can trigger a tap tempo, channel change, or scene.
Can the Lehle expression pedal send MIDI via USB?
The USB socket transmits MIDI data to a computer. It then becomes possible to control a DAW, plug-ins, or virtual instruments with the pedal.
What are the dimensions and required power supply?
The unit measures 200 mm long, 90 mm wide, and 47 mm high, weighing 766 g. The power supply requires 9 to 15 V DC, with a maximum current draw of 100 mA. The maximum rated voltage is 10 V.
