I have not heard the Salvation Legend, but I had Rob build me a Legacy...actually two of them. he said that you can't do the three amp legacy with one mod, so he built me two. The VAI is the clean side. If you play it clean, it is like a cross between a Fender and a Vox AC30....cool bell like tones. If you max the gain, it has a nice crunch, but not really even a mid gain crunch, just a nice early break up kind of crunch. The VAI AGRA is channel 2 and 3 or as best Rob could do. It starts out with a nice crunch and then dimed it screams nicely and doesn't fart out at all on the low end. Like all of my mods, there is a place for every one of them.
