so again I went through everything I tried to find the problem. Nothing.
So when I play through the amp, I can play single notes but the sound is very distorted and banging and it doesn't play long. As it couldn't get the sound last and needs loads of volume. Also when I have volume on and unplug my guitar it has like whistling sound and It stays to circulate.
Hope someone will understand and have even a tiny clue what's going on.
