Frequently Asked Questions
18V provides more headroom, resulting in a cleaner, more dynamic distortion with less compression and a more responsive feel.
While it can handle some heavier sounds, it's primarily designed for medium-gain applications; it won't deliver the extreme distortion of a high-gain pedal.
The 'Classic' setting is best suited for single-coil guitars; with humbuckers, it can sometimes add unwanted muddiness, but it can still be useful for adding warmth.
