The triaxis is not a mark series amp, and I do not see why they cannot add a larger selection in eq presets, when they decide to do so. If they can add a tone stack pre or post gain they can , add a second eq post gain , or post amp pre cab , or post cab, in respect to the cost of their programming, or processing.
Apologies. I was thinking about the actual 5 band graphic and not the Triaxis rack.
