Electro-Harmonix Blurst! Modified Filter
Electro-Harmonix · pedal
The Electro-Harmonix Blurst! is a modulated filter pedal from Electro-Harmonix, applying auto-wah-style filter modulation to the guitar signal with a modulation LFO that sweeps the filter rather than envelope-tracking from picking dynamics. Controls include Rate, Depth, and Filter Type for LFO-controlled automatic filter sweep. The Blurst delivers automatic filter modulation without requiring hard picking for the filter to respond.
