Get touch sensitivity in heaps with the Mad Professor Royal Blue Overdrive. Give your tone just a bit of dirt, roll the distortion all the way off for an EQ boost, or crank it up for a full-fledged distortion. Use the Volume, Drive, Bass, and Treble knobs to tweak the Royal Blue's transparent drive so it's tailor-made to fit in with the rest of your rig. When you have the distortion at low-to-moderate levels, you get impressive touch sensitivity determined by how hard you hit your strings.
