HI Guys, unfortunatly, I still hear bleed from my guitar … in A440. what am I doing wrong?? Carlos

Not much background to go on here, Carlos.  Written above for the H9, so I assume you’re not using an H90.  Have you followed those exact steps listed above?  What algorithm / preset are you using?

The more information about your setup you provide, the easier it will be to try & help with the diagnostics.
