PROEL GF14L Medium Impedance Stereo Volume Pedal for Digital Keyboards and Pianos
The Proel GF14L establishes itself as an essential dynamic control solution for keyboardists and studio musicians seeking precision without compromising signal integrity. Part of Proel's acclaimed "Golden Feet" series, this stereo volume pedal has been specifically designed to work with line-level sources, distinguishing itself from conventional guitar pedals thanks to its medium-impedance architecture.
Its hybrid construction combines the lightness of a high-strength thermoplastic ABS body with the stability of a counterweighted galvanized steel base. This ensures the pedal remains firmly planted on the floor during performance, even on slippery stages, offering a secure and robust feel. As a fully stereo device (2 inputs and 2 outputs), the GF14L preserves the panoramic sound signature of modern digital pianos, synthesizers, and organs, allowing for smooth crescendos and fades without sacrificing the instrument's spatial richness.
Inside, the GF14L houses a long-life 20k Ohm main potentiometer, calibrated to deliver a linear and musical response curve. A key feature is the 100k Ohm side control , designed to adjust the maximum output level. This functionality allows the musician to calibrate the pedal's volume "ceiling," ensuring that even at full volume, the signal never overloads the input of the mixing console or amplifier, granting absolute control over the dynamic range.
Main features
-
Real Stereo Design: Equipped with two inputs and two outputs, ideal for maintaining the stereo signal from keyboards and effects processors.
-
Medium Impedance (20k Ohm): Specifically optimized for line-level signals, avoiding the loss of high frequencies common when using high impedance pedals on keyboards.
-
Output Calibration: Side 100k Ohm potentiometer that allows setting the maximum volume limit for perfect integration into the audio chain.
-
"Golden Feet" Stability: Galvanized base with non-slip rubbers that provides exceptional grip on the floor.
-
Universal Connectivity: Four 6.3 mm (mono) jack connectors compatible with the vast majority of standard instrument cables.
Benefits for the musician
The GF14L solves one of the most common problems for keyboard players: the difficulty of controlling accompaniment volume without taking their hands off the keys. By incorporating this pedal, you gain superior expressiveness, allowing you to create natural swells (progressive volume increases) on pads and orchestral strings. Furthermore, its passive circuitry requires no batteries or external power, simplifying your stage setup and eliminating potential power failures.
Use cases
-
Direct with Keyboards: Master volume control for stage pianos or synthesizers connected directly to PA.
-
Organ Configurations: Emulation of the expression of classic volume pedals in digital organs.
-
Recording Studio: Manual volume automation during recording to give "humanity" to virtual instrument tracks or external hardware.
Frequently Asked Questions
-
Does it need batteries or a power adapter?
No, the Proel GF14L is a passive pedal and works without any electrical power.
-
Can I use it with an electric guitar?
While it will work, it's not ideal. This pedal has a medium impedance (20k) designed for keyboards. For passive guitars, a high-impedance pedal is recommended to avoid tone loss.
-
Does it work as an expression pedal?
Its primary function is volume control (audio passes through it). To use it for expression (parameter control via MIDI/CV), a special insert cable would be needed, but it is primarily designed to regulate the audio flow.
-
What does the side knob do?
This allows you to limit the maximum volume. If the sound is too loud with the pedal fully depressed, you can reduce this control to set a safe limit.
