Reply to usb game controller analog question

so i bought THIS
received it, and have used a hid to midi software on the pc and successfully used it with tracktor.my plans are to make a midi fighter clone with 4 knobs at the top(2x 2 axis into 2 knobs). my question is does anyone know what is the value of the potentiometers?, i do not have acces to a multimeter right know, and am planning to go to the electronic store tomorow. would be big help!, will post a build log once i receive all my arcade buttons wich i bought HERE (pretty nice website, takes long for shipping but hey, im in no hurry since theese arcade button cost less then a dollar when you buy more then 10)
so yeah, if anyone knows the value of the 4 potentiometers would help me alot!
