"The mods are:
Switched Mono mini Jack Output - Put this through your amp, PC/Laptop, mixer or Effects unit to further enhance the circuit bent sounds!

Green LED

Two Mini Switches - Both these produce a type of high squeeling noise. these do work best when the unit is slow right down.

Pitch Down Control - Takes the voices to an extremely slow speed creating grainey noise. this works well with the noise bends.

The unit does have some marks on it. Runs on 2 AA batteries"
