Its on top of the overtone page : http://ceriatoneforum.com/index.php?topic=397.0

The amp "stock"  is sounding good, but when you switch channels or engage PAB the tone/drive settings are not useable anymore.

With all the mods you have: topclass clean(much, much better!) and overdrive and PAB! All with the same tone/ drive settings. It's a balanced amp now.
Nik is making the mods standard in the amp. Soon all stock amps will sound as described.

Only thing you maybe like to do is: tweak the internal OD trimmer. Clockwise you got a more gainy sound. Counterclockwise its getting less gainy, more punchy.(Mine is 10'o clock, less gain, more punch )
