I had in my mind some kind of modeling pedal with different instrument sounds, different mic models and effects in a compact pedal for live use. Today I discovered the Zoom A3 which tic's most of the boxes, so I went shopping for one. They have been discontinued and if you can find a new one they go for around $300! Luckily, I found one for $132.00 so I snagged it. I don't have it yet, so I can't tell you if it's the acoustic modeling pedal of my dreams. The replacement has less features and less of the features I'd like. But are there any other pedals out there like an A3 with modeling features and effects in a pedal? Maybe something more for other acoustic instruments as well. I play mandolin, too and I know fiddlers who could use something like this for live shows.
