Why can't three single pickups produce the sound of pricking needles?

This is because your electric guitar equipment is not selected correctly.

To get the timbre of the needle, your pickup needs to do the following:

1, there are many options for medium and high output electric guitars, but any high-quality electric guitar with double-coil pickup can achieve similar results.

2, single compression, single compression here is optional, depending on your personal preferences, if you have a good hand and like to control the strength, you can leave it alone.

Personally, I like to add compression to make the whole sound more uniform and full, and I also like to attach some compressor sounds I like.

3, noise reduction, focus! Your timbre is not clean, except by hand, it depends on your noise reduction!

There are also different types of noise reduction. It is necessary to use a single block with very strong noise reduction ability here. It is not enough for you to raise the noise reduction door. It must be a single block with strong noise reduction ability. To put it bluntly, it is specially designed for heavy work.

4, fader Boost/ overload Overdrive are indispensable, and the most important thing is that the secret is here! A good fader/overload can make the whole tone tight! If you only rely on the gain of the speaker, the timbre will be loose, the attack power will not be enough, and you will not feel the blow from fist to flesh. The role of fader/overload is to help you do this.

5, speakers, the basis of timbre! It determines the quality of timbre and the root of style.
