First, we had a useless slow bubble tuner only good for bedroom playing. Now we have an even slower strobe tuner (which is OK for guitar adjustments).
It would nice to have a basic tuner with a quick response for LIVE playing. When you only have maybe a measure or two in the music to get back in tune, the current offerings are not fast enough.
Having to bring and setup a FAST tuner such as the Polytune to every gig because the built in tuner doesn't cut it is silly.
I know I've seen at least one or two pictures of Kemper users here on the forum with their pedal boards and there is an additional
tuner for live playing.
It really can't be that difficult if Roland, T.C., Digitech, and Line 6 can do it.
