Vertex Effects Vertex Boost MKII

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.

While the 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 off all, the Boost MKII doesn't change the tone of anything that comes before it — it's sonically invisible.

This is a customer-returned item. The pedal is in good condition and works perfectly. There is no box or expression pedal included.

Guitarists are always searching for new ways to elevate the sound of their rig. Thanks to its top-shelf input and output buffers, the Vertex Boost MKII will do just that. How can a set of buffers transform a noisy, novice-sounding rig into a quiet, pro-level one? For starters, these buffers condition your rig's entire analog signal path, ensuring optimal input and stable output. They also exhibit an unprecedented level of linearity, while ensuring zero coloration of your signal — even with dozens of stompboxes in your chain. The Boost MKII's input buffer compensates for pickups with different impedances, ensuring that both single-coil- and humbucker-equipped guitars retain every ounce of their tone, 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.
