Ah, that makes perfect sense and kinda fits with what I had assumed from looking at a couple of the pedal layouts.
To the OP - I'm also looking for a ME pedal and given that I'm too tight to pay for a new one, have narrowed my options down to a 2nd hand GT6-B (good sounds, but seems a bit complex by all accounts), GT10-B (just as good, if not better sounds, but less complex), Line 6 XT Live (simpler to use that the Boss ones, but not sure about the modelling) or the Zoom 9.1u (probably going to be a bit pricey, even SH).
I'd be interested to know which pedal you opt for in the end.
