That should be interesting.  With Aura you need to match similar images, that my be a challenge, I assume an parlor guitar for some sort?   One thing I like about Mama Bear is that is is not as image sensitive.  Let us know what you find, there are a lot to try.   I would be interested whether the Spectrum can get close to what you need.  I have a Mama Bear and have looked at whether the Spectrum would step it up.

I would be very surprised if anything worked to my liking.  I bought and tried to make a Fishman Dreadnought pedal work with my GXi... no dice.  The two guitar types have very nearly identical air volumes, but that's not the key.

My understanding is that the only way for it to "work" is pay Fishman to make the mappings FOR THAT GUITAR (the Cargo).  Any other parlor guitar mapping is going to sound "odd".

The technology now exists to create a truely generic mapping stompbox where the customer is responsible for sampling the guitar (with the stompbox in one mode) and then have the stompbox do its thing (with the stompbox in the "play" mode).  This will be the next true "breakthrough".
