Joe Satriani signature Tonex one with expansion touch screen that provides easy and instant access to all needed parameters of amp models and effects. It also has the ability to hard wire physical switches. I have a TRS jack set up for a common two button foot switch that will allow the user to scroll up and down the presets. The screen will also allow Bluetooth connectivity with a midi pedal such as the MVAVE Chocolate and allows for assignable foot switch control. Power the touchscreen with the standard 9 volt center negative barrel connector and the screen can power the Tonex through usb which is a nice feature. The screen can be used as is or it can be put into an enclosure. I was planning on building an enclosure for it, but didn't get around to it. Used in a smoke and pet free environment.
