If you used the old 'Transformer Grind' parameter (which added some high end as you increased it), then you will notice a drop in some high end.
If you used the old .Speaker Drive' parameter (which added some compression and volume as you increased it), then you will notice a drop in volume. As the old setting is carried over to the new 'Speaker Comp' parameter, which reacts in an opposite way (it adds some compression, but reduces volume and reduces high end as you increased it). So an old value of '4' would have made the preset louder overall, than a setting of '0', but now that same setting makes it quieter and darker.
If those parameters were at '0' in your preset, then not much will change. It depends on a lot of other factors too. Which Amp models you use, and how they are dialed.....How much master volume, and other 'advanced page' edits?
