Big problem with Zoom A3

[Pablomago]

I'd like to see something like the A3 but with modeling for common acoustic instruments. Besides acoustic guitar I play mandolin and Weisenborn. I have friends who play banjos and fiddles and zukes and other acoustic instruments. It would be nice to have one box to quickly switch to a preset set up for that instrument, it's EQ and whatever effects I need. I tend to use compression, chorus, delay and reverb in varying degrees. One box that could do it all and be phantom powered from the mixer's XLR input would solve a lot of problems for me.

I bought the A3 as it ticked most of the boxes for the majority of my needs. Before I just used a Baggs Para Acoustic preamp, the one without the XLR output. It's ancient but is still going strong!
