    With the original THR line of guitar amps, Yamaha basically invented a new product category: the connected desktop amplifier. It filled a need that honestly many guitar players didn't even realize they had. These amplifiers are small enough to sit on a table or desk, they sound great even at low volumes and they're stylish enough that you won't feel compelled to hide them when company comes over. You don't have to search long or hard to find people singing their praises. I bought one a couple years ago and have zero regrets. But the THR amps weren't without flaws. And in the nine years since they were introduced, the competition has caught up. The highly revered Roland Katana line made a play for the space with the Air. And the iconic Vox brand introduced Adio. So Yamaha announced the THR II in September with new features, new amp models and a rich new app in the hopes of not only keeping pace but also showing the competition it's still the benchmark for tiny amps.

    Guitar amps are getting more connected and more flexible. Boss' latest Katana offerings simulates 10 different amp models and 60 effects. While Yamaha's THR line features a rechargeable battery and wireless connectivity. Positive Grid is taking things even further. Its upcoming Spark amplifier adds both learning and musical accompaniment features thanks to its companion mobile app.

  • Line 6 Mobile In app turns your iPad or iPhone into a multi-effect amp -- party on, Wayne

    No word yet on if the volume peaks at 11, but what Line 6's new Mobile In offerings will do is turn your iPad or iPhone into a pro modeling amp, with a sick range of amplifiers, guitar cabinets, stompboxes, tones and rack effects. The setup comes in two separate parts: the free mobile Pod app and the Mobile In adaptor, which lets aspiring metalheads (or Fleeting Foxes) connect their guitars to an iOS device using the 30-pin connector. Line 6 says this connection blows similar jack-based apps out of the water, and it's throwing in 24-bit/48kHz digital sound for good measure. Although you'll get a killer 110dB of dynamic range for guitar, you can still achieve 98dBs when you plug in another mono or stereo-line level -- that old keytar, perhaps? With that kind of combo you'll be thankful to know that it records and works with other CoreAudio apps like GarageBand -- perfect for jamming out with your keyboard toutin' buddies without the back-breaking work of carrying a heavy amp. Have your lighters ready for when the $79.99 adaptor ships this fall, but until then, check out the video and full PR after the break.
