This may be a more involved question and I can take this to another thread, but what exactly was causing the volume change between 4.1 to 5 and that 5.1 addressed? The reason I ask is, I created some new presets in 5.0 after updating, and now that 5.1 is there to fix whatever happened on the volume situation, those 5.0 presets I made sound different now (not worse, just different) and I'd like to figure out what to change to try to recreate the sound I got in 5.0 on the new 5.1 firmware. Hopefully that makes sense, and I don't think it's just the channel volume because I tried that. I had finally nailed my perfect clean tone inside 5.0 and now I am not sure what dials to change to replicate it in 5.1.
