I've used an ME-50B for the last year or so, although I've just stopped using it in a band setting as I've just got a standalone compressor.
The Compressors in the ME-50B are great btw
Yeah the FX are cool! I assume that most of the technology is based on the single pedals anyway, so its going to sound good. The tuner is my only real gripe, again the technology is probably the same as the TU-2, but its got less LED's, and so therefore is less accurate.
I only really used it as an analog pedal, thats how its layed out, but it does have digital elements such as saving patch settings etc. But i have no time for that haha, much prefer my analogue stuff. And so if you need different FX during or between songs you need to physically bend down and turn the knobs or, like was mentioned above, get a latching footswitch. And you would need to program the settings for each effect to be remembered.
However, if you literally only have 2 or 3 sounds for the band, that don't vary, then its perfect!!
I use mine just for solo playing now.
If i was giving it a score, i'd go for a 7/10
Cool
