Yamaha DTXpress/DTXplorer/DTXtreme

Bought a used DTXpress and the hi-hat patch cord is flaky.  Opened it 
up and the solder job was very close to disconnected.  I tried re-
soldering with no luck.

So...any suggestions on exactly what type of patch cord I should buy 
and where I can get it online?  My local shop doesn't have a very 
good selection.

Thanks,
Chris
