That mixer may work for you
and the features look cool for an all in one solution. I just don't know how
transparent it will be as I’ve never tried it. Running the effects in parallel
sounds great but you have to consider if you want to feed one effect into
another for certain combinations.
Also, because the infamous Mesa loop will
bleed some dry signal back and cause phasing issues, you may not have any luck
with serial routing and running everything parallel may be the only option (with
killdry enabled on all processors).
The problem with that is that if you are
using a whammy effect for example, you would not be able to apply reverb and
delay to the pitch altered signal. I would find someone that can do the effect
loop mod on the Mesa and still use a splitter/ mixer configuration.
