Detuned sound with an expression pedal

I haven’t tried it but I’m fairly sure it’s possible using Morphing. There is a detune effect in the Chorus section. You should be able to control the amount of detuning by linking its range to the Morph pedal.

I've just had a chance to try it with the Micro Pitch and Air Chorus FX as well as the Depth control on the actual Vibrato effect. All work fine.

Are we talking about Vibrato or the Trem arm on a guitar (which is called tremolo even though it actually is vibrato)?

If you are looking for trem style dive bonds etc then no. You would need the pitch pedal FX for that one. This is pretty cool but doesn't sound like a real trem equipped guitar.

OK. I originally thought you were referring to vibrato like a vibrato pedal. Which is basically a chorus pedal without the clean signal mixed in.

To get a vibrato bar pitch movement you would need to use the Pitch Pedal effect. It will definitely give you a serine sound but it won’t sound like a guitar trem arm.

That should work fine on the Pitch Pedal effect

One thing to consider is that a vibrato (the way I like them) lets you vary the pitch above and below, so the "true" note is in the middle. It sounds really musical to me.

You might be able to set the Pitch Pedal effect for -1 when heel down and +1 when toe down. Maybe an adjustable center detente so "true" is easy to find.

For what it's worth, almost every guitar with a vibrato can be adjusted to stay in tune with the right set up and maintenance. That's what I do. The direct interplay between the hands and the bar is impossible to mimic, I think.

Very good point well made Finally . The sound and expression of a vibrato bar is impossible to mimic fully with anything else but the key is always in the setup.

It sounds very progressive and smooth.

That bigsby pedal sounds pretty much like the Kemper Pedal Pitch effect to me, but with more precise control over the pedal.

I'm not sure what you mean.
