I was wondering, can effects pedals affects you amp tone quality?
Ever since i have been using my zoom G2, my amp without the G2 sounds terrible.
It is fine with the G2 though, so does anyone know whats happened?

Maybe you've got so used to using the Zoom that you forgot what your amp sounded like before, and it's just not as good as you think you remember.
A recent study shows that 8% of teenagers listen to nothing but music with guitars in it. Put this in your sig if you're one of the 92% who isn't a closed-minded moron.
