Everything from retro-style axes to interstellar effects and insanely powerful amps caught our eye in Nashville.

Mad Professor Amplification's new-at-NAMM Simble Predriver gives you two levels of very fat pre-drive or clean boost (it sounded especially lovely in front of a dirty Simble overdrive.) The Evolution Orange enables you to achieve the effect of rolling back your volume knob while bumping the midrange and sculpting the bass and treble. Counterintuitive at first, perhaps, but very effective and versatile. Price TBD on both.
