Paul Reed Smith is not only known by its guitars. We can now see that they produce amps and cables, with a new product in the last category. It is a special jack, presented in the NAMM 2010: the Guitarbud. It permits to link your guitar to your iPhone, and you just have to use the PRS Jam Amp application to use it like a little amp! But the brand precise that you can also use it with other apps like Riff Raters or GigDaddy Multitrack Mixer for example. Bassists and clavierists can also try it with their apps. But the Guitarbud cost about 30 $, and Jam Amp is available on the App Store for $9,99. (via)
