Transistor, headphone output, USB input and output, aux. 10w stereo watts but true ...
3-band EQ, gain, master volume and guitar / USB (for jam on playback). Also runs on battery.

UTILIZATION

Perfect, the sound is terrible for a small amp ... It really sounds like big! No need to make a good background for his ...

SOUNDS

Metal for me, we can get what we want because it reacts with the game, the master gain volume knob and scratches ... A real amp! It takes a big drop on the gain, the knob can scratch and have a clean and crunch by turning its knob guitar ... Y has everything what it takes, believe me! Of the gain that is sent to the bottom ... It's hard!

OVERALL OPINION

1 week of use, I like the use of battery (on vacation ...) reading playback and music playback with just the iPad and iPhone hi-fi sound c is a big plus!
Definitely go there!
Yamaha app that allows you to remove the guitar part of high or low playback ...
