The Dread Pirate Roberts, my Schecter Stilletto Diamond Series 5-string. Tis all kinds of awesome. It's only my second bass (after a shitty 'Groovemaster' 4-string starter bass with one pickup), but I love the way it looks and sounds. I use Rotosound Swing R66 45-130 strings.
I've got it plugged into a Peavey TKO 115 80W combo. It may sound tiny, but it's bastard loud. Which is just as well, because it's also fucking huge.
I haven't got any effects pedals at the moment (because I'm poor

), but I would love to get a Korg synth pedal and a EMG octave pedal.
