The graphtech piezo system will give you great acoustic sound. Very clean, crisp and bright. Great for guitar players who primarily play electric but might need an acoustic tone for a few songs. You can go from your regular magnetic pickup sound to acoustic with a flip of a switch. For those of you who have never used a piezo system before don't expect it to sound 'just like an acoustic guitar' This sound will not have the depth of a real acoustic. It sounds more like an electro acoustic guitar but yet even different from that. I feel the piezo sounds best running direct to a mixer rather than an amp. This is also a great sound for studio, you can get it to sound very close to a real acoustic by tweaking the tone knob (if you install one) and using some EQ (I use a RC booster for this) However I must also mention this piezo system adds a white noise to your signal that's always running in the back ground and is boosted even more when you play through a distorted setting. It won't go away no matter what you try, even if your piezo volume is down to zero.
