Frequently Asked Questions

The Fundamental aims for a similar transparent, mid-focused response but with a slightly less pronounced upper-midrange bump and a more approachable price point.
It works well with both, but the 'Bright' mode really shines with darker humbuckers, adding clarity and preventing muddiness.
It's relatively transparent, but stacking it with very high-gain pedals can introduce a slight thickening of the tone, which can be a desirable effect depending on your goal.
