i apologize if i'm reading too much into that comment.
a broad statement was made: "do we need to reset our amps?"
the answer was "no, the firmware updates automatically."
the question is "updates WHAT automatically?"
it seems from java's latest reply above mine, that only NEW advanced parameters are "updated automatically." though this seems very obvious - a new parameter needs to be set to something, so it makes sense that the new parameter would be "updated" to the default. maybe before, a new parameter was introduced at a setting of 0 or something?
the following was written before java's latest reply directly above mine, i'm guessing it has been answered now.
i understand what update the amps all prsts, update amps defaults and "resetting the amp block" functions do.
what i'm trying to clarify is that if you update to firmware 16, does the new firmware change settings like negative feedback, power tube bias, b+ time constant (features LIKE that, which already exist in the amp block, not necessarily those features specifically if they aren't relevant or changed)?
so if i had the negative feedback set to 6.12, but the FW16 default is 2.50, will FW16 automatically change the negative feedback to 2.50?
OR...
does FW16 automatically change and default only NEW features added (not present in previous FW)?
