Because the Pico Attack Decay was not what I expected, I ordered this one instead. Immediately a click ! Very usefull for me. The volume pedal effect is just spot on, no artefacts, no searching for combinations of different knobs and ecountering useless knob combinations. Simple and straightforward. Good Sound. And the filter is really good and also simple. with two possible strenghts. You can also choose between only static resonance filtering or with a little sweep. I don't need a boss ft-2 anymore for non resonance filtering. So, this makes that this pedal is capable to give more shoegaze soundscapes then many reverb pedals can do. If you take away the attack of the guitar, add a resonant filter on high notes and then put it in front of some dirt.... you get this sonic curtains that remind of Ride and Chapterhouse and maybe Husker Du, with sixties 12 string jangle. With a very loud, ear destroying sound because of these high harmonics. And of course the all wet effect from reverse reverb is also in the sound because of the attack that's removed. I am convinced ! A pearl.
