This pedal was featured in 2018’s Bass Magazine and this is what they said:

The Filtron envelope filter pedal offers an auto wah-style effect with high and low settings depending on the definition and tone you require. With controls for Range, Attack and Decay, a fine selection of funky tones can be coaxed from this unit.

    A really sweet and dynamic envelope filter.
    Reminds me of a Q-Tron with more headroom and tonal possibilities.

    Love it.

    Brilliant Pedal!
    Very Musical Envelope Filter .
    Bin gigged the past few weeks in various different venues and I love how when you get it tuned in you retain that clean low end you’d usually loose with these kind of pedals . You can go from fast slapping funk to boarder line 80’s choppy synth ! Still Finding new sounds.
    The Pedal that keeps on giving.
    Can’t wait to really explore the rest of the range .
    Cheers Paul !
