Stick has stereo cord (jack input) so if You buy new stick You recive also stereo cable. You can use mixer (I don't know if stick also can work in MONO mode, but always You can use small mixer). Besides stick has great Bass and poor treble - so it's better to use bass amp - not guitar amp.

I dislike if somebody uses stick sounding like TWO instruments. I like a piano idea of the stick. Now stick is an underground instrument - it would need "Chopin of stick" - a great virtuoso and stick composer, who made stick nice for all (not only for tappers) to hear. So it is Your chance :)
