( i opted for the second one because i didnt want to drill a hole in my baby!)
Get a Piezo Element 1500-3000Hz like this

ok now to make it all happen
1. First carefully pry or cut off the plastic on the element. I used a cutoff wheel
2. once you have the Piezo element out solder the Your HOT wire to the copper rim of the disc
3. next take the remaining two wires and twist together and solder as one whole wire to the whit part of the dis. (make sure its close to the edge)
4. Once all soldered braid the three wires together and cut at about one foot.
5. Once all ends are spliced solder your HOT wire to the small little tabs coming off of the audio jack
6. next solder the remaining two wires to the remaining two tabs. each wires gets its won tab.
7. cut a small amount of cork or medium density foam and hot glue it to the bottom of the piezo disc.
thats pretty much it for the one i made keep in mind when i want to hook up to an amp i just use some good old scotch tape and tape it directly to the sound board. make sure you tape the piezo disc down solid to ensure a good connection to the wood.
If you want permanently use this type of pickup then use the first audio jack mentioned and drill a 3/8 hole where you want to mount it. then permanently tape the element under the bridge.
sry if its a little unclear let me if u have n e more questions thx
