Impressions...I like it, and for me and what i play (Death Metal), it's a keeper. I have only tried briefly but I like the way the knobs interact and seem to impact the sound, you can get quite a few sounds out of this box . Tested with ENGL Fireball100, Deliverance 120, Soldano Avenger and a Mesa Tremoverb heads. Used my Parker pdf85 w/ bare knuckle painkiller and a Vader 412 cabinet. The pedal matched the first 3 amps immediately and I had no trouble dialing shit up. The one where I had the most trouble was with the tremoverb's red channel, but finally found some good settings. All my testing so far has been at low/moderate volumes, will test in band practice on the weekend, but i will be keeping this pedal (first time i like a fortin product)
Disclaimer: I got the pedal almost for free since a friend ordered it for me and I gave him an Agile guitar i was selling. Guitar had no value for me so he ordered the pedal for me and kept the guitar. Maybe if I had to fork out the $250 out of my pocket i would not be as enthusiastic, but even if you wait for the pedal to hit the used market for $160-ish give it a try.
