Source Audio Blurst! Modulated Filter Pedal
Best creative tool for guitarists seeking expressive, experimental modulation textures.
The Source Audio Blurst! Modulated Filter Pedal offers a unique blend of filter and modulation effects, creating a wide range of expressive tones. With intuitive controls for Drive, Tone, Level, Blend, Attack, LFO Rate, and LFO Depth, you can sculpt everything from subtle sweeps to wild, resonant textures. Its envelope sensitivity allows for dynamic responses to your playing. Built with a durable aluminum housing and true bypass, this pedal is designed for the discerning guitarist seeking to expand their sonic palette. It's powered by a standard 9V DC supply, making it a versatile addition to any pedalboard. The Source Audio SA241 One Series Lunar Phaser delivers three distinct styles of swirling stereo phase modulation: Vibe, Classic, and Multi. Effortlessly sculpt your sound by morphing the LFO wave shape from sine to square using the Shape knob. Save your favorite settings with three onboard presets, accessible via the toggle switch positions. This pedal offers both analog buffered and true bypass options, along with stereo input and output jacks for expansive modulation. It's also compatible with expression pedals and tap tempo switches for ultimate control.

Know before you buy
Yes, the Blurst! is highly versatile and works well with bass, synthesizers, and other electronic instruments. Its envelope sensitivity and wide range of filter controls allow it to adapt to different signal levels and frequency ranges.
True bypass routes your signal directly through the pedal without any processing, which is ideal for maintaining a pure signal path. Analog buffered mode helps maintain signal integrity over long cable runs, preventing high-frequency loss.
While the pedal allows you to save and recall three presets directly via the toggle switch, you can access up to 128 presets by connecting the pedal to the Source Audio Neuro Hub via MIDI.
The pedal operates on a standard 9V DC power supply. Please note that it requires 150mA of current, so ensure your power brick or adapter can provide sufficient amperage for stable performance.
The Neuro Mobile App unlocks deep editing capabilities, including advanced signal routing, parametric EQ, and additional modulation algorithms. It essentially allows you to customize hidden parameters that aren't accessible via the physical knobs on the pedal.
Yes, the pedal is compatible with expression pedals, allowing you to map parameters like LFO rate or filter frequency to your foot for real-time, hands-free manipulation during a performance.
