I currently own the Digitech BP200 and I notice that it just doesn't live up to what I want in an effect pedal... So the question is in comparison to the Bp200, is there a difference with the Boss ME-50B?

Any input would be nice.

*I notice that Digitech has released several remakes of the guitar multi effect pedals, but it seems as though they have forgotten about us bass players?*
I've used both, I can tell you now the ME-50B is far more superior and versatile in terms of usability and sound/effect quality.

However, if you want a real effects pedal, I suggest saving up the extra for a Boss GT-8B or similar.
