First, let me say, this is a great sounding pedal, especially for the price! I have no complains about the sound at all.
The only thing I personally dislike much is the user experience. It basically force you to save your tweaks/settings into the memory (there are 2 preset memory slots). If you don't save it and try to use the pedal as other "normal" pedal meaning tweaking the knobs, then playing, then turning the pedal off, and later turning it on, you'll find out it actually loaded the current memory preset instead of honoring the knobs settings/positions. I understand that this was desired behavior by design, it's just I expected something else... And of course, if you get used to saving your settings to presets all the time before switching the pedal off, then you are good to go with no complaint.
But for me, if it didn't have those preset memories, I'd be happier :)
