This is my non-guitar, likely acquisition for this year. I've had good results with the Korg KR-mini but options are limited. Nothing bad about it, it got the job done. New for 2018, the KR-55 Pro has more lone ranger jam features for people who play with themselves (like yours truly) & external storage for other inspirational moments. More importantly, the 55 remains portable with battery power option for on-thego applications. Here's hoping that Korg keep prices sensible.
