From the vendor
Envelope filter, i.e. an automatic wah controlled by the signal envelope, is an effect commonly used in funk and reggae music as well as among guitarists who like to experiment with the sound. Thanks to the nomal / bass switch, it works great not only with the classic E tuning as well as with very low tunings, seven-string and bass guitars.
PCB. Dimensions: 51mm x 31mm.
