What are the differences between hsh and hh in terms of their features and benefits?

The main difference between HSH and HH guitar pickup configurations is the addition of a single-coil pickup in the HSH setup. This allows for a wider range of tones and more versatility compared to the HH configuration, which only has two humbuckers. The HSH setup offers a balance between the warmth of humbuckers and the clarity of single-coils, making it suitable for various music styles.
