I had my Kemper for six months and toured the UK with it, but was bored of having the same tone for everything live, so decided to buy the remote to make my life easier...
BEST DECISION I HAVE EVER MADE. The Remote gives you the ability to change your tones and add/remove effects easier than with any pedals or footswitches ever will.
The only bad thing about the Kemper Remote is the flimsiness of the screen, it feels like very cheap plastic, so I would 100% recommend buying a screen protector from reverb (also fits on the screen of your rack and/or toaster Kemper
Would 1000000% recommend this magical piece of equipment, don't settle for third party, this is what you want... This is what you NEED
