The Overdrive is SMOOOOTH !

The Vertex Ultraphonix is amazing. I got it after I bought the Steel String and I love that pedal lots. It's my always-on pedal as it has that special sauce makes my clean tone sounds much better. The Ultraphonix on the other hand is my dirt channel and it covers the rest of the spectrum. The OD is very smooth and dynamic with a mild mid bump which is great for soloing. It response to your guitar volume knob really well too. You may nail the Larry Carton or Santana tone easily with it and it stacks well with the Steel String too. Certainly one of my fav OD out there.
