I've been playing a Phase 90 for about 10 years and I'm thinking it's time for an upgrade. I was thinking about a Grand Orbiter but then I came across the Chase Bliss Wombtone. I love that it can take an expression pedal but it seems like there's too much tweakability (plus $$$). Looking for some recommendations…basically something more advanced then a one-knob Phase 90. Not opposed to spending around $200.
