Barely used Line 6 Spider V 20 MkII 1x8" 20-watt Modeling Combo Amp, with USB cable.
This little fella is super-versatile all by itself, with so many sound options it can take a little while to find what you like.
But with the USB cable and the free Spider V Remote app, the possibilities become infinite!!!
I love the heck out of this thing, but I've barely used it since I mostly play bass now.
