I like to mess around with my looper to harmonize things sometimes and I just found something that sound pretty cool.
Basically you take a root note and a third(or any other interval you like to use when harmonizing things) and you alternate between the two and the other one does in the reversed order.
For example when you have Dm. You let one guitar play D-F and the other guitar play F-D. In this was both the F and the F will always sound like they are being played and it's weird because I couldn't get the same Sonic effect by just tremolo picking the respective notes.
