Steel String Supreme

The Ultraphonix Overdrive is designed to re-create the overdrive produced by a Dumble™ Overdrive Special amplifier. Four Overdrive Specials were used in the voicing and calibration of the Ultraphonix, each amp ranging in origin from the years 1970-1990. Being modeled after four different generations, the Ultraphonix accurately captures the character of the legendary Dumble™ amplifier, regardless of the minute and more apparent differences in the amp from year to year. The Ultraphonix is more than able to provide the D*style overdrive in front of any clean amp platform. Engage the Ultraphonix in tandem with another overdrive pedal or in front of a broken-up amp to really cut through a mix with a huge lead tone or thundering rhythm tone.

THIS PEDAL WILL TRANSFORM YOUR GUITAR RIG

Don't let the Vertex Boost MKII's name fool you — it's much more than a mere boost. Make no mistake, this multifunction guitar pedal can function as a gain booster, with +16dB of ultra-transparent gain that can either drive your amp into saturation or give your solos a squeaky-clean level bump, depending on where you choose to deploy it. Able to accommodate both line- and instrument-level signals, the Boost MKII also includes ultra-linear input/output buffers that are guaranteed to elevate the sound of your entire rig. This stompbox's buffers can propel a typical mid-level rig into pro-level territory with zero tonal coloration. And if your rig is already 99% of the way there, the Boost MKII will deliver that elusive missing 1%. Beyond that, the Boost MKII's insert jack enables you to adjust your volume via an external treadle-style pedal while keeping your guitar's signal completely isolated — it's like plugging straight into your amp. Boasting a compact enclosure that's 33% slimmer than its predecessor, the Vertex Boost MKII belongs on every tone-obsessed guitarist's pedalboard.

Boost MKII

The Vertex Boost is expertly crafted to be a clean boost, buffer and volume pedal in one. The Boost is designed to leave your tone unchanged, while boosting the level of your signal. The Boost also features an ultra-linear buffer to condition your line with ZERO tonal coloration, even with dozens of pedals in your chain. Additionally, you have total volume control by connecting the Boost with any EXP or Volume Pedal and adjusting your volume as you would with a normal volume pedal. When the Boost is OFF, the EXP will function as a volume pedal (sweeping from silent to unity gain). When the Boost is ON, the EXP or Volume Pedal will control the boosted volume (sweeping from silent to wherever the Boost level knob is set). Since your guitar signal is isolated from the impedance of your chosen EXP or Volume Pedal, your tone remains open and full-range, and most importantly, it feels like you're plugged straight into your amp.
