For says it on the tin "clean" I like the Tucana Clean and the Hook 1a, but also amps like a JM45 (or a plexi), AC20, or Mr Z Mz-30 with the Input Drive lower (and/or Input Trim to 0.5)... the Div/13 CJ (with cranked MV and bass turned way down) sounds great with single coils, (not so much for humbuckers though).
All that said, I think my time honored preferred clean sound in the Axe has always been the Euro Blue Vintage with the drive around 3, bright switch on, and then the MV and Presence turned up between 6-7 or so... gives a little hair when you hit it harder, but has a nice body and sparkle to it played softer.
