What makes the Lehle Stereo Volume pedal 'wear-free'?

It uses a Hall effect sensor to measure the pedal's position via a magnet. Because there is no mechanical friction between a wiper and a resistive track, as found in standard potentiometers, the internal components do not degrade over time.

What is a Blackmer® Stereo-VCA?

It is a high-quality Voltage Controlled Amplifier used to adjust signal levels. By using this instead of a direct potentiometer, the pedal maintains high audio fidelity and eliminates the noise typically caused by moving parts in the signal path.

Can this pedal be used to split a mono signal?

Yes, the pedal is capable of taking a single input and splitting it into two separate outputs. This is useful for driving two different amplifiers or signal chains simultaneously.

Does the pedal support summing two signals?

Yes, the device is designed to sum two inputs into a single mono output. This allows musicians to combine two different instruments or signal paths before sending them to an amplifier.

Is the pedal's physical resistance adjustable?

Yes, the mobility of the pedal can be finely tuned. Users can adjust the low-friction bearings to make the pedal travel tighter or looser depending on their personal playing style.

Does this pedal require a power supply?

Yes, because it utilizes active VCA technology and Hall effect sensors, it requires a power source to operate. It is not a passive device like some basic volume pedals.

Where is the Lehle Stereo Volume Pedal manufactured?

The pedal is manufactured in Germany. It features high-quality German-made components, including the Hall effect sensor.

How does this pedal prevent 'tone suck'?

By using active VCA technology, the pedal ensures the input impedance remains consistent and the signal is buffered. This prevents the loss of high-end frequencies that often occurs with passive volume pedals.

Can it be used with keyboards?

Yes, its stereo inputs and high-fidelity signal path make it an excellent choice for keyboards and synthesizers. It can handle the line-level signals typically produced by these instruments.

What is the typical price range for this pedal?

The pedal typically retails for approximately £239. This reflects its premium build quality and advanced electronic components compared to standard mechanical pedals.

Is the pedal suitable for touring professionals?

The pedal is specifically designed for professionals, featuring a robust housing and wear-free sensors. These features ensure it can withstand the rigours of constant travel and heavy stage use.

How does it compare to a Yamaha FC7?

While the Yamaha FC7 is a widely used expression pedal, the Lehle Stereo Volume is a dedicated high-end audio attenuator with internal VCAs. The Lehle offers a more robust build and a cleaner audio path for primary volume control.

Lehle Stereo Volume Pedal

The Lehle Stereo Volume Pedal is a professional-grade signal control device designed for high-precision audio attenuation without the mechanical wear of traditional units. It utilizes a German-made Hall effect sensor and Blackmer® Stereo-VCA technology to provide noiseless, accurate volume sweeps for guitarists and studio musicians.

Overview

The Lehle Stereo Volume Pedal is a robust, precision-engineered tool designed to address the common failings of traditional volume pedals. Unlike standard designs that rely on a mechanical potentiometer—which is prone to dust, scratchiness, and physical wear—the Lehle unit employs a non-contact Hall effect sensor. This sensor measures the distance of a magnet to determine the pedal position, ensuring that the signal path remains clean and the physical mechanism remains durable over long-term professional use.

Technological Features

At the heart of the device is a premium Blackmer® Stereo-VCA (Voltage Controlled Amplifier). The audio signal does not pass through a variable resistor; instead, the Hall effect sensor sends a voltage control signal to the VCA to adjust the level. This architecture eliminates the 'scratchy' noise often associated with carbon tracks. The pedal also features high-quality low-friction bearings, which contribute to a smooth, steady travel that can be physically tuned to the player's preference for resistance.

Signal Routing and Versatility

As a stereo device, the pedal offers significant flexibility in signal management. It can be used in several configurations:

Stereo Control: Managing a full stereo signal path from keyboards or stereo effects pedals.
Signal Splitting: Taking one input and sending it to two separate outputs.
Signal Summing: Combining two inputs into a single mono output.

This versatility makes it suitable for complex pedalboard setups where signal routing is as important as volume control.

Sound Character and Performance

The sound of the Lehle Stereo Volume is characterised by its transparency. Because the audio is managed via high-end VCAs, the pedal avoids the high-frequency loss (often called 'tone suck') that can occur with passive volume pedals. The sweep is described as exceptionally smooth, providing a linear and predictable increase in volume that is ideal for ambient swells and precise level adjustments during live performance.

Comparison to Alternatives

When compared to traditional options like the Dunlop Mick Ronson Cry Baby Wah or common expression pedals like the Yamaha FC7, the Lehle distinguishes itself through its wear-free electronic design. While pedals like the Boss NS-2 or DD-3T focus on specific effects processing, the Lehle acts as a utility foundation. Its pricing at approximately £239 reflects its position as a premium alternative to entry-level utility pedals from brands like Behringer or Fender, targeting users who prioritize signal integrity and mechanical longevity.
