I've been using a Zoom MS-50G for a few months and know the basics of the UI for the A3. Even so it took a little work to figure the A3 out. The manual is written in a way that is confusing if you don't have the A3 powered up and in your hands at the same time. The A3 gives you two effect slots and one guitar model per patch memory. You control the guitar model target in the patch and you control the description of the source instrument through a knob and switch. Compared to a Fishman Aura, it sounds best at 100% processed mix, which would sound horribly chorus-ie for the Aura. It does a really nice job making my solid body Traveler MkII (LRBaggs Active Element) sound good (it normally sounds mediocre -- but for travel you make some compromises) and it takes my RainSong S-OM1000N2 up a notch to (near?) perfection. For the solid body Traveler I went with a D-28 target, and a Yamaha Silent Guitar plus Piezo source. For the RainSong I used the Taylor 314c target and the single cutaway plus Piezo source. A touch of tiled room reverb and the Neumann U87 microphone model (set pointed at the sound hole) nicely fatten up the amplified tone. Now at this point (target guitar model + reverb + microphone model) I've completely consumed all three simultaneous effects, which means no added chorus, delays, etc. without dropping the mic model or the reverb. I am looking for a nice clean signal and don't see that as a limitation for me. I did turn off the auto save feature to make sure I did not trash my saved patches by mistake. There are knobs for equalization and I found a little treble roll-off was good for both of my guitars. The Traveler through the Zoom A3 gives my Telecaster Acoustasonic (Fishman Aura Image Casting equipped "solid body acoustic") a decent run for the money. I think you could choose to like either the best, though I prefer the Tele Acoustasonic. (Posted on 7/10/2013)
