Feature:
Input Check, True bypass check, two different distortion setings you can toggle check. The only thing I would change on this thing is that the eq on the pedal applies to both distortions. This can be fixed by running a Boss EQ on the insert channel on the pedal. The insert channel only applied to distortion 2 (red)

Quality:
A freaking tank. This product has convinced me to only buy pedals of this quality from now on. All steel, buttons are sturdy. Makes Boss pedals seem like cheapy crap.

Value:
I have bought mutiple distortion pedals over the years. All of them except for this one are broken or sounded like so much crap they were not work buying in the first place. This was actually really worth it, especially for those using solid state amps that want that tube tone.

Desirability:
I actually want another one so I can mod one just for guitar and one for bass. You can switch out the Plexi tubes with harder or softer tubes and create your own sound. The tone bone has me looking at other Radial products too... they make good pedals.

Sound:
10 on sound because this thing is so versitile. I have used this for both bass and guitar. I initillaly bought it becase I was having a very hard time finding the right distortion pedal for bass. Because of how versitile this distortion pedal was I thought I would give it a shot, an expensive long shot but man did it pay off. This thing freaking has tone and if you have tone it will do nothing but add to it. Supposedly this thing is a combo of the tone bone classic and a mutation of the tone bone hot british.

Ease of Use:
Took me quite some time to get the hang of this thing. Its a lot of pedal and you basically have to sit with it for some time to get the right sounds. Expect to rework your amp setting too. I suggest getting the best clean tone you can and then working the pedal.

Support:
Have never needed it, but the pedal did come with a great how to fix the thing yourself manual. I am sure if needed I could fix this thing with what they provided. The whole thing in pretty simple on the inside

Overall:
Overall this thing was a way better buy than I expected. I have had it for a while and it has proven to be a core element in my writing now. As I said I want two, so of course I would buy another one if it broke. But the great thing is I probably wont have to unless it falls into a trash compactor, drop it off a building or you ran it over by a bus or something you can fix it yourself.
