Simplifying Tonepad Rebote 3 Delay. Need help verifying schematic.

[nguitar12]

So I am going to build Tonepad Rebote 3 Delay.However this circuit is a bit complicated and so I decided to make a simple version. I don't really need the modulation and want to make it with two pt2399 chip (originally have 3 chips). I am not sure whether I canceled a component that do not supposed to be canceled. I am not good in electronic so I am making this schematic by guessing. I need someone carefully check it for am cos I don't want to spend a few days on building a circuit with mistake and doesn't work at all. Many thanks.

Here is the schematic I made:



And here is the original:
