Question 1

What do I attach this to to record sounds?  Does it have to be a special connection?

Accepted Answer

The piezo unit has a standard 1/4 jack (same as a guitar cable) for the output. There are adaptors that will go from 1/4 inch jack to any analog input you're using.
The sensors need to be firmly attached to whatever you plan to record to pickup the vibrations in order to create the output signal.
Note: The audio quality of this unit is not very good, It's sort of works for synthesized drum triggers and works for window alarm sensors for security systems. I tested them on a guitar and ukulele and it sounded like recording inside a tin can. Kind of noisy, frequency response between 300hz - 1.5Khz with many unwanted resonate overtones giving it the tin can sound.

Question 2

Do you need a preamp to get the sound?

Accepted Answer

No, the pickups are pretty powerful.  You can run straight to an external amp. You do get a lot of sound from hitting the body of the guitar with your hand, however they are pretty nice, and it's a very good price.  Hope this helps.

Question 3

I bought this.  The cable jack only goes in about 3/4 of the way, but still works.  Should the cable jack go in all the way?

Accepted Answer

It should go all the way in. Remember part of the jack is supposed to stick out to hold the strap in place.

Question 4

Do I need a pre amp to use this or can I just plug it directly to the amp?

Accepted Answer

Depends. If you are near the amp, you can plug straight in. If you are on stage trying to go through a DI, you will need a preamp before the DI.
