Can you folks elaborate on null filter use? What does it do and how do you set it?
It's actually just called a "filter Block," not a "Null Filter", but many call it a "Null Filter" because they are just using it as a volume controller and not using any of the filters.
I am of the opinion that using a filter block for simply boosting volume is a complete waste because every block already has a volume control that can have a controller attached to it, that can do exactly the same thing.
Additionally, a more efficient way IMO, if you want to hit the front of the amp harder and are not using any blocks (like a drive block, etc) in front of the amp block, attach a controller to the
Input Trim of the Amp Block [
[Enabling Boost (12dB) is equivalent to setting Input Trim at 4] or attach a controller to the boost control. You can even attach the same controller to both (or more) parameters if you want more boost than the boost will give you. It's just a matter of utilizing the available options and spending 5 minutes to think it through.
If you want a post amp signal boost (to increase overall volume), attach a controller to the amp blocks mixer section output volume controller.
Cliff put in a lot of time and effort to give us all these options. It's so disappointing to see people would rather use the volume control off a filter block instead of utilizing the options already available that were designed to do this. Also, For guys like myself that are using a preset per song that involves 5-8 scenes and maxed out presets hitting 85-90% CPU, adding another block, no matter how small the footprint, is not an option.
Disclaimer : My opinions are my own, and I do what seems logical and what works the best for me. Also, try to remember this is not a real amp and there really are no rules. Play with it, try different things.
