Worry not about the ruggedness of your on-the-go audio solution by picking up the Yamaha PDX-11 Portable Speaker System ($100). It packs a four-inch woofer and dedicated tweeter into a small, octogonal enclosure that sports a 3.5mm input, top-mounted iPhone/iPod dock, and an integrated metal handle that makes it perfect for grab-and-go use.
Not content to simply mimic the looks of an old-school, cassette-powered system, the iHome iP4 Boombox ($200) borrows the general shape and attitude of classic systems but belongs squarely in the 21st century, thanks to its subdued monotone design*, modern technology like SRS TruBass DSP, a flexible iPod/iPhone dock, four-inch carbon composite woofers and one-inch tweeters, an auxiliary input jack, backlit buttons, a five-band graphic equalizer with LCD display, and a decidedly low-tech FM radio.
*Applies only to the gray model. We don't do fuchsia.
Put the full power of an The Edge-style effects stack at the tip of your toes with the DigiTech iPad Pedalboard ($500). Combining a powerful iPad app that boasts 87 different adjustable pedals, 54 amps, and 26 cabinets with a physical case/interface that provides access to up to ten pedals, one amp, and one cabinet using nothing but your feet, the Pedalboard offers nearly endless creative possibilities. Technical specs include quarter-inch plugs for guitar input, amp and effect loops, output, and external footswitch control, with dedicated stereo XLR and headphone outputs, and even a USB port for audio streaming. And don't worry about stomping next to your iPad — just try not to stomp on it when things get rowdy.
