PROEL GF12L - Mono volume pedal for keyboard and line input with 20k Ohm potentiometer
The Proel GF12L is an essential tool for keyboardists and musicians who require precise, dynamic control over their sound in real time. Part of Proel's renowned Golden Feet series, this mono volume pedal has been specifically designed to handle line output signals, offering a smooth and natural response that respects the integrity of the original signal.
Unlike standard volume pedals designed for passive guitars, the GF12L features an internal architecture optimized for low- and medium-impedance instruments, such as synthesizers, digital pianos, and sound modules. Its core technology consists of a high-quality 20k Ohm potentiometer , ensuring linear and precise volume control. This allows for subtle level increases and complete silence without abrupt jumps or unwanted noise, maintaining the instrument's tone throughout the pedal's entire travel.
The device's construction is remarkably robust. It utilizes high-strength thermoplastic materials combined with a metal base that provides stability and weight, preventing the pedal from slipping during energetic performances. Its ergonomic design offers a comfortable operating angle, allowing the musician to keep their foot on the pedal for extended periods without fatigue. Connectivity is simple and straightforward, with 6.3 mm mono jack inputs and outputs located on the side for easy integration into any stage or studio setup.
Main features
-
Line signal optimization: Designed specifically to handle output signals from keyboards and other active instruments, avoiding impedance matching problems.
-
Precision potentiometer: Equipped with a 20k Ohm component that offers a smooth and musical volume curve, ideal for creating "swell" effects or controlling the live mix.
-
Golden Feet Series Construction: Combines a durable casing with a non-slip base, ensuring durability and stability on any surface.
-
Standard connectivity: It has one input and one output via 6.3 mm (1/4") mono Jack connectors, compatible with the vast majority of instrument cables.
-
Passive operation: It does not require batteries or external power sources to operate, simplifying setup and eliminating worries about lack of power.
Benefits for the musician
Using the Proel GF12L transforms the way you play. It frees your hands for playing while you control the dynamics with your foot. This is crucial for organists who need expressiveness, or for keyboard players who want to gradually layer sounds (pads). Furthermore, it acts as a safety feature: by turning the volume down completely, the musician can disconnect their cables without creating dangerous clicks in the PA system.
Use cases
-
Live keyboardists: To control the overall volume of the synthesizer or digital piano without releasing the keys.
-
Samplers and Drum Machines: Volume management for individual mono outputs in electronic music setups.
-
Active stringed instruments: Basses or guitars with active preamps that require a medium/low impedance (Low-Z) pedal.
Frequently Asked Questions
Does this pedal work for a normal (passive) electric guitar?
It's not ideal. Guitars with passive pickups require high-impedance pedals (generally 250k or 500k Ohms) to avoid losing brightness or tone. The GF12L is designed for line-level or active (20k Ohm) signals.
Does it need batteries or a power adapter?
No, the Proel GF12L is a completely passive pedal. It works simply by being inserted into the audio signal chain.
Is it a stereo pedal?
No, this model is mono (1 input, 1 output). If you need a stereo version, you should look for the standard GF12 model.
Project description
