In general the improvements are subtle but there should be improvements in the "bounce" and slightly smoother power amp distortion. I realized I wasn't accounting for the fact that bias excursion is a function of the B+ voltage. I also derived more accurate formulas for the behavior of the various power tubes when they enter saturation. The improved OT modeling results in fewer ultrasonic overtones which, while inaudible on their own do result in more intermodulation "garbage" when playing multiple notes so you should hear better string separation and chord clarity.
)? After updating, I noticed my Mark IV patches sounded/felt tighter & the lower strings didn't sound as full. This seemed like too big a change in sound & feel for this update, not that I really understood all that tech-talk in the release notes. :mrgreen I had by chance messed around with the Power Amp Hardness parameter just a couple of days ago (trying it at 4 vs the then default 3), and it dawned on me that's what I was hearing after updating, which is what led me to discovering the setting had changed.
