One nice change would be to finally get away from bulky 1/4 jacks for patch cables. That should be a significant cost/space savings right there for board owners. If you did need a 1/4-inch jack to use a single module with a guitar or bass, or to loop out to a standard pedal, then a simple panel with six 3.5mm jacks normaled to their 1/4-inch counterparts would probably be more than you’d ever need. And an easy DIY if you needed one.
