Feature:
Don't really need too many features on this. What's on the pedal is all you need.
Quality:
It's a Boss pedal and it's built like a tank.
Value:
For the price I got this for it was worth every penny. Get a daisy chain to supply other effects pedals that you have.
Desirability:
I got tired of hearing the unwanted noise from my amp at shows and band practices, so I wanted this pedal.
Sound:
I keep reading a lot of reviews about how it kills your tone. The only difference that I've noticed was just a little bit of a volume decrease, but all I have to do is turn it up louder. I am using this pedal on a 200W Traynor tube amp head and a Marshall 1960A cabinet. It will definitely kill the unwanted sound immediately.
Ease of Use:
It really wasn't that hard to get it setup. But I will tell you right now, READ THE INSTRUCTIONS! It will tell you what the knobs do and how to set it up properly. Once I read the instructions I set it up in no time.
Overall:
Since I own the Metal Zone pedal, I expect this to last for a very long time. I've only had a few effect pedals go bad on me, but they weren't Boss products. If it ever went bad on me I would definitely buy another one.
