What is the primary technology used in the Lehle Dual Expression?

The pedal utilizes magnetic sensor technology based on the Hall effect. This allows the device to track the position of the treadle without any mechanical contact or friction.

Does the Lehle Dual Expression use a potentiometer?

No, it does not use a traditional potentiometer. Because it uses magnetic sensors, there are no mechanical parts to wear out or become scratchy over time.

How many devices can this pedal control at once?

It can control two separate analogue devices simultaneously via its dual expression outputs. Additionally, it can send MIDI data to a computer via USB at the same time.

Can I use this pedal with a computer?

Yes, the pedal features USB connectivity. This allows it to send MIDI data directly to a computer for controlling software plugins and DAWs.

Is the pedal prone to mechanical wear?

The manufacturer describes the pedal as wear-free. The absence of a mechanical potentiometer eliminates the need for frequent maintenance and part replacements.

What is the typical price for the Lehle Dual Expression?

The pedal typically retails for approximately £189. Prices may vary slightly depending on the specific retailer and current market conditions.

Does this pedal require a battery?

Like most active expression pedals with sensor technology and USB capabilities, it requires a standard power source to operate the internal electronics. It does not operate as a passive potentiometer-based pedal.

How does the size of the pedal compare to others?

The pedal features an optimised size designed to fit efficiently on modern pedalboards. It balances a comfortable treadle surface with a footprint that saves space compared to larger vintage-style pedals.

Can the Lehle Dual Expression be used for studio recording?

Yes, its USB-MIDI functionality makes it highly valuable in the studio. It allows for precise automation and control of virtual instruments and effects within a recording software environment.

Is this pedal suitable for live performance?

Absolutely, its robust construction and wear-free design are specifically intended to withstand the rigours of live touring. The dual outputs also allow for complex live routing setups.

What makes the Lehle different from a standard Boss or Yamaha expression pedal?

Unlike the Boss or Yamaha FC7, the Lehle uses magnetic sensors rather than physical pots. It also offers dual outputs and USB-MIDI, which are features not found on standard budget expression pedals.

Can I control a Digitech Whammy Ricochet with this pedal?

While the Whammy Ricochet is a related effects pedal, the Lehle Dual Expression is designed to work with any device that accepts a standard expression pedal input or MIDI over USB. You should check the specific connectivity requirements of your effects pedal.

Overview and Technology

The Lehle Dual Expression represents a significant advancement in expression pedal design by replacing traditional mechanical potentiometers with magnetic sensor technology. Utilizing the Hall effect, the pedal measures the movement of the treadle through magnetic fields rather than physical friction.

This design philosophy addresses the primary failure point of standard expression pedals: the potentiometer. By removing mechanical contact, the pedal is effectively wear-free, eliminating the scratchy signal and eventual component failure common in older designs. The unit is housed in a robust chassis designed to withstand heavy touring use while maintaining a footprint optimised for modern pedalboards.

Connectivity and Functionality

A defining feature of the Lehle Dual Expression is its ability to interface with multiple systems simultaneously. It provides two separate analogue expression outputs, allowing a single movement of the foot to control parameters on two different effects units at once.

Beyond analogue connectivity, the pedal features a USB port. This allows the device to function as a MIDI controller when connected to a computer, sending expression data directly to Digital Audio Workstations (DAWs) or MIDI-compatible software plugins. This hybrid nature makes it equally suitable for live pedalboard integration and professional studio recording environments.

Performance and Character

Because it relies on magnetic sensors, the Lehle Dual Expression offers a smooth, linear response that is not affected by dust or dirt. Users can expect precise manipulation of data, which is critical when controlling sensitive parameters like delay feedback or filter sweeps. The lack of mechanical resistance from a potentiometer contributes to a fluid physical action, providing a consistent feel regardless of how long the pedal has been in service.

Target Audience and Comparison

This pedal is intended for professional musicians and sound designers who require reliability and complex routing capabilities. It is particularly well-suited for users of high-end digital delays or multi-effect systems where dual-parameter control is advantageous.

Compared to entry-level alternatives like the Yamaha FC7, the Lehle offers significantly higher durability due to its magnetic sensor. While traditional pedals like the Boss series are industry standards for basic tasks, the Lehle's inclusion of USB-MIDI and dual-output functionality places it in a specialized category of high-performance utility gear.
