Every model is different...I changed the amp model in the amp block of one of my main presets from "Friedman HBE" to "Euro Blue Modern". The level on both is set to -12 dB but the output of the Euro was much, much lower.
Can't determine what is causing the difference.
It's normal. Just use the output level to get it to where you want it to be.Yep, I realize that. But the difference this time is unusually stark. Doesn't seem normal.
