I use this fxpedal with my Warwick Corvette Standard 4, with my Warwick BC60 80w amp and it's just awesome. I use this pedal for playing metal, rock, funk, all of them with different settings ofc.
The things I love about this product is it's range in sound. You can have a full-on hard fuzzy dist, or just a slight crunch. The silicon switch is great aswell, turn it off to get a lighter sounding tone and you can hear that the input and output are 2 different tones. Turn it on to get a deeper tone where in- and output are put together.
Also its a compact and simple pedal, easy to understand, it also includes a manual with some simple settings.
The one thing that I dont like that much is a matter of taste, personally I dont like fuzz that much, but thats the one thing.
Dont forget to buy a 9v power supply and an extra cable and you're ready to rock!
TL;DR:
Great pedal with a wide range from heavy fuzz to a tiny crunch. Easy to use. Remember power supply and cable.
Cheers!
