The guitarist for my brother's band has a Boss ME-50 and a Digitech GNX 3000. He currently uses the Boss, but Personally I thought the GNX sounded just as good. Is there a big difference in sound quality between the two? (I only heard the GNX on one or two different settings)
Nope, no sig here.

Havn't heard of the GNX but I'd get the Boss me-20, sounds a lot better.

I have both, and both are very good units but are totally different. The GNX has amp models the boss doesn't. If you have a tube amp then the boss is better. The boss is alot easier to setup and use for live use, the gnx is great for recording or going straight into the PA.
