Simple to use and nice output sound. It sounds 70's and funky when you snap the guitar. Top!

Envelope filter pedal that I use with basses. As with all products from the EHX brand, which I particularly appreciate for the solidity of its products, the casing is very sturdy. 2 knobs, Drive (effect level) and Q (effect range) and a frequency band selector swept by the effect. You have to be meticulous in the settings to get the desired effect, alone for a funky effect or with a fuzz for a noisy side, everyone can find their happiness. Note the presence of a trimpot inside the pedal, but it is not indicated in the manual so I did not touch it. A must-have on a bass pedalboard in my humble opinion.
