The PBF4 is a sophisticated Grid Series 3 grid module designed specifically for musicians, producers and live performers who value precise and reliable control. Equipped with four faders, four potentiometers and four mechanical buttons, this compact device offers a sophisticated interface for a wide range of applications - from DAW controlling and synthesizer control to individual MIDI mappings.

Every control element of the PBF4 has been developed with a focus on haptics and durability. The faders with a metal axis and medium resistance enable smooth, precise movements - ideal for fine adjustments of volume, expression or effect components. The linear potentiometers are also equipped with a metal axis and ensure a smooth turning feel combined with high resistance. The setup is complemented by four mechanical buttons with Gateron Hall effect technology, which provide fast, tactile feedback - perfect for trigger functions or switching modes.
Each control element has its own RGB LED display, which not only provides a visual
Another highlight of the PBF4 is the magnetic connection system, which allows modular expansion with other grid controllers in any direction - whether vertically, horizontally or as a complex setup - the possibilities are virtually unlimited. The robust design with injection-molded housing base and solid front panel guarantees maximum stability even under intensive use.
