I love using straight vibrato for some lush chord work. Somewhat simulating bending the neck back and forth, however some necks are too stiff and in the higher registers the neck can't be bent much.
I can't really get the sound I liked with some stomps for this on the Kemper. It seems the crossover, even though it's down at 20 Hz, lets some unaffected signal through? At least it definitely sounds somewhat "chorusy" and not like the pure vibrato I like.
Any chance of removing that crossover? Or whatever it takes to get a pure vibrato?
I'd also love having ducking on it. Making the vibrato appear a bit after notes are hit.
