Line 6 has been known to push the boundaries of guitar amps: It was one of the first to offer built-in effects for that type of gear. Now, the outfit says it has reinvented the amplifier once more by packing Bluetooth streaming and iOS app controls into its new Amplifi 75 and 150. For learning new riffs alongside Kerry King or simply for easy listening, the amp is compatible with Android, iOS, Mac and PC gadgets for beaming tunes from your repository of choice. To further integrate that mobile device, Line 6's Amplifi Remote iOS app toggles every dial from an iPhone or iPad. That piece of software also accesses a cloud-based community for sharing and rating tones in addition to storing amp, pedal and effects presets for safekeeping. Looking to get your axe sounding like the Slayer guitarist's rig? Automatic tone matching can pull sounds from those iTunes tracks to do just that.

As far as specs go, Amplifi is available in either 150 or 75 watts, as their numeric labels suggest. The 150 houses a 12-inch Celestion speaker as part of its five-speaker stereo setup while the 75 packs an 8-inch "custom speaker." Line 6 says that this arrangement offers a "truly immersive guitar experience" that's never sounded so "wide and spacious." Both units offer wet/dry effects to boost said sound quality, tap tempo/tuner, four onboard presets and USB connectivity. If that sounds like the kind of innovation you're after, the pair is priced at $400 and $500 respectively, and both are available now from guitar retailers. You can take a closer look at the amplifier in the video that awaits after the break.
