Hi,
I have one of those ( Boss Micro BR). I've recorded with an Vox Adio , The Kemper will do Great as well !! Its a very handy record/practice tool and these days quite cheap when you can find one on the used market ! Easy as hell and no computer necessary to use it
wherever and whenever you want to record your ideas or band practice. Its very good for what it is and quite small - I can highly recommend it ....
