Vertex Boost MKII Pedal

The Best-Selling Vertex Boost Made Better!

Written by

Elliot Stent

Vertex's best-selling Boost pedal has not only been shrunken down — it's been enhanced with more functionality than its predecessor too! The new Vertex Boost MKII is ready to take your tone to the next level, going beyond what many standard gain boxes can do despite its super-simple, one-knob interface and compact chassis design.

Offering up to +16dB of pure, ultra-transparent boost that can either drive your amp into saturation or give your solos a squeaky-clean level bump; this powerful multi-function stompbox is also able to accommodate line/instrument-level signals and includes ultra-linear input/output buffers that are guaranteed to elevate the sound of your entire rig.

Vertex Boost MKII | The Gold Standard for Clean Boost Just Got Smaller!

Much More Than a Mere Boost!

Boost MKII's buffers can propel a typical mid-level rig into pro-level territory — with zero tonal colouration. 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!

+16DB of Extra, Transparent Gain

While the Vertex Boost MKII offers a myriad of useful functions, it's a clean booster pedal at heart. Its straightforward 'Level' knob ranges from unity gain to a healthy +16dB. Placing the Boost MKII in front of your amp or dirt boxes adds saturation and sustain to your signal, while placing it after your preamp and dirt boxes gives you a full-range level increase. Best of all, the Boost MKII doesn't change the tone of anything that comes before it — it's sonically invisible.

Optimise Your Signal Path for Maximum Tone

Thanks to its top-shelf input and output buffers, the Vertex Boost MKII will improve the sound of your setup. Conditioning your rig's entire analog signal path, these buffers ensure optimal input and stable output. They also exhibit an unprecedented level of linearity, while ensuring zero colouration of your signal — even with dozens of stompboxes in your chain.

The Boost MKII's input buffer also compensates for pickups with different impedances, ensuring that both single-coil and humbucker-equipped guitars retain every ounce of their character, while its output buffer tackles arena-sized cable runs like a champ. Got a hissy, interference-prone passive effects loop? Not anymore — the Boost MKII will convert it into a max-quality, whisper-quiet active loop!

Volume/Expression Pedal Compatible

On the rear of the Boost MKII, you'll find a 1/8-inch TRS insert. This enables you to control your volume using an external treadle-style pedal. When the Boost MKII is bypassed, your external pedal will behave as a typical volume pedal — sweeping from zero to unity gain. Turn the Boost MKII on, and the treadle-style pedal will sweep from zero to wherever the stompbox's 'Level' knob is set.
