Here's What Lehle Say About the Mono Volume S

With the LEHLE MONO VOLUME S you get an active and wear-free volume pedal, which is lighter and smaller but not less efficient: equipped with the proven and evolving magnet sensor VCA technology of the other LEHLE VOLUME pedals, you control the volume of your instrument precisely.

As it has no mechanical potentiometer, the typical noise, endlessly expensive repairs and complicated adjustment can be avoided.

Your foot is just moving the magnet, while the Hall-sensor measures the distance, with great precision and very fast. An ARM Cortex CPU processes the data of the sensor in a matching, musical taper and controls the VCA. Here, the signal path is always kept completely analogue – and in your hands.

Stability – both electronic and mechanical.

Over the entire control range the LEHLE MONO VOLUME S transmits the full sound spectrum of the connected sound source. The input and output impedance always stays the same, ensuring that unlike with potentiometers, there will be no damping of higher frequencies.

The input voltage coming from your power supply (9 – 12 V) is internally rectified, then filtered, stabilized and transformed to 30 V, thus achieving a total dynamic range of 120 dB. The high-end preamp with discrete

Class-A input stage brings every little sound nuance to life – your tone becomes touchable.

There are no initial difficulties with the LEHLE MONO VOLUME S: low-friction bearings of a high-performance polymer bed the shaft gently into the aluminium enclosure and reduce any mechanical stress towards zero – thus, it runs mechanically extremely smooth and steady. By means of an adjusting screw the tension of the pedal can be modified with great precision from feathery to Vintage Car.

In addition to the mains output, a second also buffered direct output is available: without affecting the sound negatively, you can provide a signal to a tuner, to a DAW or even a second amp.

Zero to hundred or boost à la carte? The LEHLE MONO VOLUME S has a boost available, which can deliver up to +12 dB more gain with a little extra emphasis (push) in the toe position. When and how? By means of using a little button you can recall presets: 0 dB, +5 dB or +10 dB. The preset P4 is the chef’s speciality and remains an audiophile surprise.

The USB-C socket provides the functionality to calibrate, program and update the LEHLE MONO VOLUME S – by the way it sends MIDI data to your DAW or amp simulation of your choice.

Compared to the LEHLE MONO VOLUME we were able to reduce the weight by 50 % and the size by 35 % – with the same rugged stability and yet more dynamic. It’s even 2 cm flatter, however the pedal range stays the same – just as comfortable and responsive as the larger models.

This is the LEHLE MONO VOLUME S: more volume – but half the size.

Brand

Lehle

Lehle is a high-end manufacturer of guitar pedals, known for their precision engineering and sophisticated signal routing capabilities. The brand is highly regarded for its innovative designs, particularly in the realm of volume pedals and signal processors. Their products, such as the Lehle Mono Volume S and Lehle Parallel SW II, are favoured by musicians for their transparency, tonal clarity, and durability. The Mono Volume S, for example, offers a smooth operation with low friction bearings and a boost function that can enhance the gain for specific tones. It also features programmable presets, a USB-C socket for calibration and updates, and a buffered direct output, making it versatile and highly functional for modern pedalboards.

Lehle pedals are built with high-quality components, including discrete Class-A input stages, which contribute to their excellent dynamic range and ability to handle various instruments, from electric guitars to keyboards. Their use of true-bypass circuits and advanced switching technology ensures minimal signal loss, allowing musicians to maintain the integrity of their sound even when switching between effects.

MIDI

MIDI pedals use the Musical Instrument Digital Interface standard to communicate with other guitar pedals, effects units, and hardware. They allow control over presets, parameters, and switching across multiple devices from a single controller. MIDI integration makes it possible to build complex, synchronised pedal setups while keeping control simple and consistent.

New

This is brand new, fresh in, and a UK warranty is included. New Gear always comes from trusted UK music retailers.

Preamp

A preamp pedal shapes and boosts your guitar’s signal before it reaches your amp or recording interface, giving you control over tone, gain, and headroom. It acts as the first stage of amplification, adding warmth, clarity, and character while preparing your signal for the next part of the chain. Some preamps emulate the response of classic valve circuits, while others offer clean, transparent tone shaping ideal for acoustic instruments or direct recording setups.

Used on its own, a preamp pedal can serve as the foundation of your tone, providing a consistent core sound wherever you play. When combined with other effects, it enhances dynamics and helps each pedal sound more defined and natural. Whether you’re looking to push your amp harder, bring life to a dull signal, or refine your sound for the studio, a good preamp pedal adds presence, punch, and musicality to any rig.

Tuner

A tuner is an essential pedal or device that helps keep your guitar perfectly in tune by detecting the pitch of each string and showing whether it’s sharp or flat. Tuners come in many forms, from simple clip-on units to advanced pedalboard models with bright displays and muting options for silent tuning on stage. They ensure accurate pitch, stable tone, and a more professional sound, making them one of the most important tools for any guitarist.

Volume

Volume pedals control the output level of a guitar signal using a foot-operated treadle. They allow smooth volume swells, dynamic control during playing, and easy muting between songs. Volume pedals can be placed at different points in the signal chain to either control overall loudness or adjust gain and drive behaviour when positioned before distortion or overdrive pedals.
