Despite being built like tanks some Boss pedals are better than others !

I had a run in with a Boss "Amp factory" (GP-20) some years a go and I'm only just beginning to forgive them !

I also think that like everything else it is important it get the right tool for the job. Example, you are not going to be impressed with the results from a blues driver or a tube screamer if you want a flat out death metal sound.
