i just picked up this used Yamaha silent guitar today and this video is a quick demo of it PLUGGED STRAIGHT INTO MY ZOOM Q8 VIDEO CAMERA WITH NO EXTRA EFFECTS
sorry i didn't sample the 3.5 audio input Jack for you (it allows you to plug in a audio cable from your phone or mp3 player and play it through your guitar so that you can play along with it together through your amp or headphones)
