First

This time, I will explain about "AMP".

Firstly, your guitar's cable joint to AMP.
To have to take attention is that you must not turn on AMP before you joint your guitar to AMP.
If you don't try this, your guitar and AMP will break!

Secondly, please look at AMP's upper.
Can you see some switchs there? These are "EQ switchs".
If you twist the switch "volume", the sound which is from the AMP is being big.
So you can make your favorite sounds, If you can use this EQ switchs well.
Of course,it is too difficult to master make sounds through EQ switchs for amateurs.
But you will master them, If you try hard and through many experiences.
Good luck.
