There are very mixed reviews on the new Tyler Variax Firmware 1.81 Acoustic models:
Five updated models. The updated models are based on* the Martin® D28, Martin® D12-28, Martin® 0-18, Guild® 12 String, and Gibson® J200 acoustic guitars.

I'm not thrilled with the new acoustic models. I may roll the firmware back. The new acoustics have a more 'roomy' sound, as if the mic was placed farther away from the soundhole. Its a nice sound for some uses, but I would much prefer have a more direct sound.
I will load into one of my Tyler Variax's and make A/B comparisons of the old vs new Variax Acoustic Models.
I sure wish they would provide Tyler Variax owners the same controls as the old 2005 era Variax 700 Acoustic - with variable Compressison, etc.
