There seems to be 2 types of firmware upgrades, the ones where the amp modeling is altered only slightly, or not at all, and results in a better sound without any adjustments to existing presets, and the major ones like this.
To be more specific, pre V3, I spent a lot of time on the advanced parameters for my two, high gain stereo, L R amp blocks. After V3, I made many small adjustments in basic and advanced parameters. It’s a bit tedious, a few hours, but I think the end result is better than before. I thought the highs were a bit harsher in 2.05 as a result of my trying to to get the detail I need. After V3, I was able to back off the highs and dynamics and make more use of the MV, resulting in more roundness and clarity with less harsh highs. I’m talking values of less than 1.
Also, the improved interaction between the power amp sections and cab blocks which, along with some slight IR alignment adjustments, seems to allow frequencies to stack up better with multiple IRs. I think I was fighting against some notchy, phase things between the 3 IRs per side I use, and their individual interactions with the power amp sections of the amp blocks. Post 3 tweaking, dialing in the balance between the IRs got easier, as did the L R balance between the 2 amp blocks themselves.
So, for those of us who adjust advanced parameters and use gain settings at the more extreme end, why would it be a good idea to reset the amp block? I know which advanced parameters I adjust, why not just go back and make small adjustments in those areas? From a workflow standpoint, I don’t see the point of resetting all parameters and starting from scratch after a big firmware change, unless other stock parameters I haven’t adjusted, have been changed as a result of the upgrade. If that’s the case, I’d rather have a list of those new baseline parameter values as opposed to a reset/starting from scratch or tweaking advanced parameters without knowing what other values have changed. One way is more work than the other, but forces you to use only your ears to get where you want to go, but it can be a lot of work. I think knowing which parameter values have changed first will intuitively enhance my understanding of how everything works together, and may also give some indication which advanced parameters to readjust first.
Does all this make sense?
