Guitar Pickup, Preamp and Effects System,Very Cool Soundhole Pickup

You can put on your favorite acoustic to enhance your tone and mix in studio-quality effects, all without an amplifier. And, when you need to plug in, you get all the available effects and controls right at your fingertips, plus some nifty adjustable tone enhancements to bring out the absolute best in your favorite acoustic.
The outstanding feature of this pickup is that it amplifies your guitar's sound, without plugging into an external amplifier. It does this with a small transducer that adheres to your instrument's back. You get delay, and reverb, plus the ability to blend an electric pickup sound, with a small microphone that picks up the acoustic sound coming from your own guitar body. You can also plug-in with the usual 1/4 inch jack.
