Who knows the meaning of electric guitar single and double shake?

Double vibrato and single vibrato refer to the vibrato system of electric guitar, that is, the metal bars and a series of vibrato systems on the piano in the eyes of outsiders. Single shake can only press the handle, and the tone can only drop; The double pendulum can be lifted up and pressed down. This kind of piano is generally difficult to debug, and it needs to be tuned several times before it can be regarded as a standard sound. If it's a high-end product, it's ok. After all, the tune is not out of tune, but if it is a low-grade inferior product, it will be troublesome, and it will be adjusted at both ends in three days. The vibrato system is generally installed at the tail of the electric guitar. Beginners are advised not to use electric guitars with vibrato system. To use a piano with vibrato system, it is necessary to master the handle skills, which will make the tone more gorgeous, but there are also guitarists (such as SLASH, OZZY, etc. ) Who doesn't use Tik Tok depends on how you like to play. As for the effect and speakers, this can't give you a final conclusion. It depends on what style you like. The higher the timbre, the better. I think beginners should focus on practicing skills instead of pursuing the perfection of timbre. Buy a low-grade one, and then change the equipment purposefully when you have a direction for the effect and timbre.
