the following presets represents over 3 hours of my time to try to get a preset to sound very close to the eleven rack with Epsi. the cab sim/mic/eq curve i chose is about the best i can do without using a second eq that i normally reserve for pre-amp model use.

hopefully you guys will enjoy this preset:

try changing the amp model to another amp to see which amps sound best through that speaker setup. i find that low/mid gain amps with plenty of mids works the best.
