Vertex Effects are obsessed with harnessing the tone, response and feel of the legendary D-style guitar amp. Their Ultraphonix Special Overdrive MKII is designed to do just that; delivering the blooming mid-range and screaming overdrive of this iconic amplifier used by the likes of Robben Ford and Larry Carlton. When you engage it, the Vertex Ultraphonix MKII will unleash your guitar's full-throated potential with an articulate attack and smooth sustain.
Frankly, the Ultraphonix MKII Special Overdrive is one of the most convincing D-style pedals we've ever heard. It allows you to recreate that highly-coveted American boutique amp sound without having to re-mortgage your house! Ultraphonix MKII not only captures the same great tone of the original Ultraphonix too, but it's also one-third smaller and provides more control over your overdrive tone, EQ and saturation.
Based on Genuine Dumble ODS Amps
Vertex claim that the R&D for the Ultraphonix pedal took over 4 years, and almost a half-dozen Dumble amplifiers! From 2012 to 2016, they ahold of five Dumble Overdrive Specials to most accurately voice the Ultraphonix pedal, comparing to "real deal" Dumble amps owned by world-famous players.
The Ultraphonix Special Overdrive MKII emulates the the expansive mid-range and strident cascading gain stages of the D-style amplifier, distilling its essence into the most authentic-sounding "amp-in-a-box" pedal.
Versatile Tone-Shaping Controls
To help you create your ultimate tone, the Ultraphonix MKII has extra gain-shaping controls beyond the original MKI version — with Master Volume, Input Gain "Level", and Distortion/Saturation "Ratio". Players can fine-tune their pickup outputs with the input gain control to get the same reaction from the overdrive irrespective of using single-coil or humbucking pickups, with up to 8dB of level compensation available.
Plus, get additional presence and harmonic saturation using the Filter knob for sculpting the upper-mids from 800Hz to 1.6kHz. Once you get the perfect mix of overdrive and EQ, use the Master Volume control to set your final output level. No matter where you set it, this pedal will sound amp-like at all volume levels.
