I was going to buy the smaller version, when i saw this "Pro" variant had just released. I assumed it would be a bigger and better version.
I'm disappointed in the handling/interface of the product. The software that i found here on Thomann (but not Harley Bentons own page), is not working at all (crashes on start). And working with the product using the display is not great. There's no preset overview, so flipping to a desired preset can take ages (All presets + their variants). The physical knobs for tuning the virtual knobs are hard to control, a little to fast and you increase the value 50%, too slow and it takes ages.
The sound is really good IMO, this is my first multi effect pedal and I've only used Guitar Rig before, but i much prefer the physical control and sound of this already.
