Yesterday saw the release of FW: 1.12 for the AXE-FXIII. It features, among other things, some great enhancements to the Multidelay and Reverb blocks. Cliff put up a demo preset featuring a nice clean Twin which I've turned into lava with a FAS 6160 and matching cab. Crikey, what a sound. Here's a taste. I'll put up something a little more comprehensive shortly.
