Critic Reviews

Marcel van Oort's Guitars and Equipment: Review: ZVEX Super Hard-On

marcelsguitars.blogspot.com

The ZVEX Super Hard-On Boost impresses with its versatile tone range from a subtle clean boost to a Hendrix-like distortion, maintaining signal integrity with stylish flair. However, its high output voltage is a double-edged sword, notorious for being "super hard" on amplifiers, potentially damaging sensitive circuitry. While it’s a gem for true tone purists, its lack of an external power jack and awkward pedalboard fit are notable drawbacks. For those with space and budget, pairing a clean boost with a separate distortion pedal might offer more control and safety for your amp.

The ZVEX Super Hard On Boost pedal shines with its simplicity and effectiveness, offering a dynamic range from subtle crunch to smooth drive with just one knob. Its unique, hand-painted design adds a personal touch, though the crackling sound when adjusting the knob might be off-putting to some. Nonetheless, it’s a powerhouse for those looking to boost their amp’s natural tone without altering it. Overall, this pedal is a robust and artistic choice for musicians seeking a high-quality boost.
