Personally I would go with an AC30... but any Fender tube amp is good for clean stuff honestly. They're not good for much else... but atleast they're reaaaally good at that.
Normally for the best clean tone I go low volume and mic my Deville and run it through the PA... so that's something to take note of too. You may not need as much wattage with a clean amp as a distorted one if you run it through the PA.
