This is a fully customized item, which was difficult to create, but I am very satisfied with it. I have treasured it in my collection, but I am now selling it.
Full custom details:
The LCD screen is IPS and the backlight can be changed with the buttons.
For touch control, there is a sensor on the top center of the screen, slightly to the left of the hidden screw, so you can change it by touch.
The LR buttons have been changed to clicky triggers, providing a satisfying feel.
The volume buttons have been changed to gold.
The charging socket has been changed to Type-C, so it can be charged with a Switch charger.
The power LED lamp changes to green when charging.
It changes to blue when powered on.
As described above, it is a completely full custom.
It is very rare to find a product with this level of full customization.
Regarding the volume, I considered installing an amplifier, but I decided against it because there have been many reports of sound distortion.
Therefore, the volume level is normal.
