Can you attach any pickup to guitar?

In theory, you can attach any pickup to a guitar, but whether it will sound good or function correctly is another matter. Different pickups are designed to work with different types of guitars and musical styles. Some pickups are specifically designed for electric guitars while others are intended for acoustic guitars. For example, a humbucker pickup is typically used for electric guitars and provides a thicker, warmer sound, while a single-coil pickup is more commonly used for acoustic guitars and provides a brighter, more twangy sound.

Additionally, the type of guitar you have will determine the type of pickup you can install. For example, solid-body guitars typically require a different type of pickup than hollow-body guitars.

Also pickup has specific dimensions depending on guitar model, so it might not fit if holes drilled for previous pickups are not suitable for new model.

If you are unsure about what type of pickup is best for your guitar, it is best to consult with a guitar technician or luthier. They can help you choose a pickup that will complement your guitar and musical style.
