It’s hard to believe that as recently as ten years ago, it was normal—nay, required—to use cameras, video cameras, voice recorders, calculators, notepads, MP3 players, clocks, flashlights, and maps. Now that a single cell phone can handle everything we once asked of those devices, it seems positively quaint to use something else.

The trend toward increased functionality is obvious in music tech, too. Witness the plethora of portable multi-function bass units—from Tech 21’s SansAmp to the Darkglass Microtubes B7K Ultra—that do double or even triple duty as DIs, preamps with EQ and compression, and overdrive units.
