The Boost MKII by Vertex is a multifunctional guitar pedal designed to provide a clean boost, buffer, and volume control. It offers a boost pedal with +16dB of ultra-transparent level over unity gain, allowing it to drive your amp into saturation or give your solos a clean level bump. The pedal accommodates both line- and instrument-level signals and features ultra-linear input/output buffers that condition the entire signal path with zero tonal coloration. The input buffer compensates for pickup loading, while the output buffer handles long cable runs effectively.
The Boost MKII is 33% slimmer than its predecessor and includes an insert jack that enables volume adjustment via an external treadle-style pedal while keeping the guitar's signal isolated and free of "tone suck." It also offers the capability to control volume using an external volume or expression pedal, ensuring that the guitar's signal remains isolated from the impedance of the chosen pedal.
The pedal is designed to leave the tone unchanged while providing up to +16dB of clean boost, making it suitable for various use-cases, including adding saturation and sustain to the signal when placed in front of an amp or dirt boxes, or providing a full-range level increase when placed after preamp and dirt boxes. The Boost MKII is known for its ability to transform a noisy passive effects loop into a high-quality, whisper-quiet active loop.
The Boost MKII's technical specifications include:
- Dimensions: 4.5” x 2.2” x 1.8”
- Power Connector: 2.1mm barrel (center negative)
- Input Impedance: 1M ohms
- DC Voltage: 8.0V
The pedal is assembled in California and is designed to provide total control of the output level via an expression pedal, making it a versatile and essential addition to a guitarist's pedalboard.
