Any of you guys mess with the preamp and piezo settings in any of the Peturcci guitars?

I was just curious who here has messed with the preamp settings on their JP models and what kind of settings you have if your willing to post a picture or share. Also curious if there’s like a factory default that comes with them which I’d love to see also if anyone has one they haven’t messed with. I’ve been messing around with the settings a lot so I was just curious what people are using. Would be especially cool if Maddi showed us johns preamp settings.
