Your bass is active, but I really hate amps that label the pad or padded input "active". Unless the inputs are designed for low versus high impedance it is complete and utter nonsense.
Most of the "active" inputs on bass amps are just loaded so they reduce the gain of the signal from your bass. usually by 10dB. This is helpful when you have a very hot signal and can't raise the gain knob without clipping.
On your Ibanez, the output of the stock electronics is not very hot and you don't need to use the pad.
For volume pedals, you need to get the active version so that the impedance matches fairly closely and it works correctly.
The switch on that bass should be a frequency shift between 250hz and 600hz, but, unless you bought it new, there is no way to know for sure without just flipping it and seeing what it does.
