*The volume thing was just a warning that if you play at real loud levels and you go and crank up the PEQ with that narrow band cranked like I explained you could potentially damage something. You’re NOT running a risk if you're not pushing your gear already close to its limits however.* Just do it at a comfortable listening level, that’s all I’m saying.
As long as you’re using Axe Edit using the PEQ should be somewhat self explanatory by looking at the graph. Although it’d be helpful if it were a bit bigger, you’d be able to see it & dial it in, in finer detail. Just remember when using it, Bands 1 & 5 the Filter type can be set with the drop down box.
And like 666 above was saying the Filter Block can be a great tool as well, I use it all the time, just about all my patches, but as a clean boost and low/high cut & sometimes mid boost before the Amp Block.
I could send ya a patch if ya wanna take a look at how I use it if ya like.
