I was looking into getting a new amp to further my guitar abilities, because my Line 6 amp is falling apart. I really wanted to get a Tube amp at an affordable price, so I was leaning towards a smaller Vox or Fender amp. I was looking at the features the Vox Valvetronix 50W has, and it said it had a number of song presets to simulate sounds by certain guitarists on certain songs. What songs would these be? It doesn't seem to say.
