I'll admit that I haven't used a lot of compressor pedals, so feel free to bear that in mind. This pedal is great quality, and as I have found with this TC range in general, is a well designed pedal. Switchable between true and buffered bypass, but on loss of power defaults to true, so you don't lose signal. It comes across as a very well thought out bit of kit.
With the toneprint app on a computer, the range of parameters you can edit is massive. You can almost certainly get any compressor sound you want out of this. I bought it with the aim to have a really transparent compressor that you barely know is on, other than the extra sustain. It definitely achieves this, but it took me a bit of tweaking to get to where I was really happy.
That's basically my only complaint. The default settings could be a bit better I think. They aren't bad, but I don't think they show off the pedal to be as good as it can be. If you like to tinker, then this is probably the only compressor pedal you would ever want
