Behringer BM-17 Frequency Box

The Behringer BM-17 Frequency Box is a vintage-inspired analogue effects pedal that turns your guitar, bass or synth into a wild, expressive sound generator. Centred around a voltage-controlled oscillator, it can move from thick fuzz tones to full-on modular synth-style chaos, all while letting you blend your dry signal for anything from subtle movement to complete sonic meltdown.

Inspired by a legendary 1990s pedal, the BM-17 captures that cult sound in a compact, rugged enclosure that is ready for the stage or studio. With envelope control, a wide frequency range switch, drive and blend controls, plus an expression pedal input for real-time manipulation, it is a powerful creative tool for players who want to push their sound far beyond standard distortion and modulation.

Vintage Analogue Frequency Madness

At the heart of the BM-17 is a voltage-controlled oscillator that reacts to your playing, delivering everything from snarling, synth-like fuzz to screaming, self-oscillating tones. Because it is fully analogue, the pedal responds organically to your dynamics and instrument volume, giving you a tactile, musical feel that is perfect for experimental rock, electronic textures or sound design.

Expressive Envelope Control

The envelope section lets the oscillator track the attack and decay of your notes, so the effect opens up and closes in time with your playing. This makes filter sweeps, pitch dives and frequency surges feel incredibly expressive under your fingers, ideal for funky stabs, glitchy riffs or evolving drones that react to every nuance of your performance.

Blend, Drive and Range for Precise Shaping

With dedicated blend, drive and range controls, the BM-17 gives you detailed control over how extreme things get. Use the blend control to mix your clean signal with the oscillator output for anything from a subtle edge to full synth takeover, while the drive control sets how hard your input hits the circuit. The range switch shifts the oscillator into different frequency zones, letting you dial in low, growling movement or piercing, high-pitched effects.

Ready for Pedalboard Experimentation

The compact, rugged design of the BM-17 makes it easy to drop onto any pedalboard, and it comes alive when combined with other effects. Run it into delays, reverbs or modulation for huge, evolving soundscapes, or place it before filters and pitch shifters for complex, modular-style textures. Add an expression pedal and you gain hands-free control over key parameters, turning the BM-17 into a highly playable performance instrument in its own right.

• Vintage Analogue Frequency Box Circuit - The BM-17 is an authentic recreation of a sought-after 1990s frequency box pedal, delivering rich, organic analogue tones that range from thick fuzz to wild, synth-like sounds, perfect for players who want something more adventurous than a standard distortion.
• Voltage-Controlled Oscillator with Envelope - A built-in voltage-controlled oscillator, shaped by an envelope follower, tracks your playing and modulates the frequency in real time, giving you expressive sweeps, growls and bleeps that move naturally with your picking dynamics.
• Blend, Drive and Range Controls - Dedicated blend, drive and range controls let you fine-tune how much of the oscillator you hear, how hard you hit the circuit and which frequency band it occupies, so you can move effortlessly from subtle enhancement to full-on experimental sound design.
• Expression Pedal Input and Pedalboard-Friendly Design - An expression pedal input allows real-time control over key parameters for live performance, while the compact, rugged enclosure is built for easy transport and reliable use on stage or in the studio.
