What are the different types of guitar capos available in the market and how do they affect the sound and playability of the instrument?

There are several types of guitar capos available, including spring-loaded, trigger-style, and screw-on capos. Each type applies pressure to the strings at different points, affecting the sound and playability of the instrument. Capos can change the pitch of the strings, making it easier to play in different keys and creating a brighter or warmer tone. The type of capo used can also impact the ease of changing positions on the fretboard and the overall feel of the guitar while playing.
