Sound — 8
I'm using it with a Fender Double Fat Strat and a Marshall AVT50 amp and I thought it made the amp alot less noisy, almost silent when not playing. I also have a metal master pedal and it cuts almost all the feedback from there too. If you wanna tap though you can't set the threshold to max which is the only downside. 3/4 the way will do fine though.
Overall Impression — 8
I play the old heavy metal from the '80s mostly and it works pretty good at cutting feedback. It's not perfect, you still will have to mute the strings with your fretting hand so they won't buzz, so don't expect a flawless sound like on your favorite CD. The only downside was that it was $80 which I thought was kinda pricey.
Reliability & Durability — 8
It looks pretty reliable. I've only had it for 2 days though. It was lighter than I thought it would be.
Ease of Use — 10
Very simple to use. There's only 2 knobs for adjusting how much noise you wanna cut.
