How is Roadie 4 different from Roadie 3?

Quite a few upgrades! Here’s what’s new: 

• Smarter tuning: we completely revamped the tuning algorithms and audio circuit to deliver better noise immunity, faster performance, and even more accurate tuning. 
• Now, Roadie 4 can also automatically detect which string you're on and tune it precisely.
• Bigger, sharper display: 1.9” full-color LCD screen with 179×320 resolution, almost twice as sharp as Roadie 3.
• Improved ergonomics: Taller build with an anti-slip back for a more secure and natural grip during use.
• Improved peg connector: Redesigned to fit a wider range of tuning pegs, both larger and smaller.
• All-New scroll wheel: Makes selecting tunings and navigating menus faster and more intuitive.
