It is the first single effect (well... dual) pedal I bought and I am very impressed so far! I've been using it for the past two weeks with a Schecter diamond Omen extreme Fr and a Vox VT20+. The sound is amazing! The versatility and the sensibility of the knobs is huge, I was never able to get the same sound twice. It also reacts very well with dynamic playing and with the toggle switch of my Omen extreme. The result is an endless cloudscape of sound possibilities. Still wasn't able to get clear delay repeats (like in Dream Theater's surrounded solo for example), but I still need to get to know Cirrus better.
I have also tested it connected with my Boss GT100+ and both the delay and the reverb remain very clear and distinct even with more complex distortions or effects. If you're into Explosions in the Sky and Post-Rock, this is the thing!
The pedal seems really well built and I love the design and the led placement. It arrived well packed in a card box with some sort of paper straw which I really dig: extra points for sustainability, KMA!
Definitely in love with KMA, can't wait to test other pedals.
