VERTEX ULTRA PHONIX GUITAR OVERDRIVE MKI PEDAL

Velcro and tape on bottom of unit

Vertex Ultra Phonix Overdrive MKI
The Ultra Phonix MKI is Vertex’s interpretation of the classic D-style overdrive voice—touch-sensitive, harmonically rich, and dynamically reactive. Designed to capture the feel of a pushed boutique amp, it delivers smooth sustain, articulate midrange, and a responsive breakup that shifts naturally with your picking intensity. Ideal for players who want amp-like drive without masking the character of their guitar or rig.

Key Features

• Dynamic, Amp-Like Gain Structure
  Breaks up gradually with pick attack, offering everything from edge-of-clean grit to saturated lead tones without losing clarity.
• Responsive Tone Control
  Single tone knob adjusts overall brightness and mid presence, making it easy to match different guitars, amps, and stage volumes.
• Open, Harmonic Midrange
  Voiced to emulate the signature D style bloom, giving chords dimension and single notes a smooth, vocal quality.
• Excellent Stacking Behavior
  Works well before or after boosts and other drives, maintaining articulation and preventing frequency buildup.
• High-Headroom Output
  Level control provides enough push to drive tube amps or sit cleanly in front of modelers and FX loops.
