Independent shopping perspective
The Korena take
Blurst applies oscillator-controlled filter movement to guitar or bass. Instead of following playing dynamics like an envelope filter, its internal oscillator drives the modulation, making the effect independent of how hard you play. An analog low-pass filter with adjustable resonance and three waveform choices lets you shape that motion. Tap tempo and expression-pedal control add further control, while the included power supply gets the pedal powered from the start.
Strong match
Who this is for
- Guitar or bass effects chains that need internally driven filter modulation alongside other effects.
- Players who want to control the modulating filter with tap tempo or an expression pedal.
Consider the trade-offs
When to look elsewhere
- Players who want the filter movement controlled by their playing dynamics rather than an internal oscillator.
