Some of the reviews I read are negative, which is surprising but, at the same time, something I do respect. IMHO, when it comes to sound there is nothing set on stone; it all comes down to personal taste. My very fist guitar pedal was a BOSS (actually it was a distortion pedal, but not this one), and I still have it and use it. BOSS builds quality lasting products. This company is owned now by Roland, which is mainly known for their keyboard line. I don't see any compromise in quality, though, and the tone (which is the most important aspect of getting a guitar pedal), is top notch. Again, this is for my personal taste. If you like other pedals, it's great, but trashing this product just because you don't like it, it's kind of not fair.
