The Lehle Dual Expression is an active expression pedal built around a Hall-effect magnetic sensor that eliminates mechanical wear entirely. Unlike conventional expression pedals that rely on physical potentiometers prone to drift and failure, this German-engineered controller uses a contactless magnetic field measurement system calibrated to a fixed internal magnet. Two digital potentiometers generate expression data with analogue voltages, delivering accuracy far beyond mechanical designs. The result is a pedal that never needs adjustment or maintenance while providing repeatable, precise control over two independent outputs.
Both outputs accommodate expression inputs from 5kΩ to 100kΩ, with switchable polarity for TS, TRS, or RTS configurations stored via soft-push buttons. The 10kΩ output doubles as a latching or momentary switch when the pedal reaches full toe-down position, enabling amp channel switching or device function control. USB connectivity transmits MIDI data directly to software without additional interfaces. High-performance polymer bearings ensure low-friction movement, with an adjusting screw for pedal tension customisation. Lehle reduced weight by 50% and size by 35% compared to their Mono Volume pedal, standing 2cm flatter while maintaining full pedal range and the same rugged construction standards.
