If someone else doesn't post a link, i have a wiring diagram at home for this set up should do fine. It's fully possible to run both pick up and piezo/pre-amp through a single cbale.
The rod should fit snug, with the saddle atop it. Silicone or glue in the case may dampen the sound, and i can't say i've ever seen either used on a rod piezo.. Snug in the slot, with the saddle. String will make sureof the rest, just like an acoustic!

Wont be home for at least another 2 or 3 hours man. If no one helps before then i'll put it up. In the mean time there are many skilled people in the forums, that might also have a diagram or a link to one. I'll check back when works over for the night.

^I like this set up, just throw your pre-amp in between the switch and the Piezo.

both these are by Ted Crocker and from the man's site, so if you see him, throw him a big thanks. (www.handmademuiscclubhouse.com)

try looking for the Pick up and Wiring Group here on the nation, they'll be your best help for quick info, and advice.

By 'external preamp' you mean u wanna keep the preamp outside the box so you can use it on multiple guitars?
There's a smarter circuit. I'll draw it out for you tonight

Yes I want to make a little box where I'll fit in the little preamp.So I can later use it on different guitars.Going to use a preamp/equilizer used in western semi acoustic guitars. Is this a good idea?

It sure is. You don't need to open your guitar to change the battery out and it'll save you money on preamps and batteries. Id reccomend a steel container like a small cookie tin so it's fully shielded

I have a pic of what you want on here somewhere but I don't know how to make it show up here. "PreAmp In A Can" picture # SDC10910. Sold it, so I'm working on "PreAmp In A Box" between other projects. It really is better than trying to stuff a preamp in a CBG. You can check it out on my page, I think.

well this is how i would do it.

note the TRS (stereo) jacks.

the advantage of doing it this way is that when you use a regular guitar cable the piezo is shunted to ground and you never hear it.

ie, lets say you put this circuit in two guitars, but only build one preamp tin, and your friend comes over to jam.  He plugs one of your axes into a guitar amp, well he only has the mag pup, you need a stereo cable to use both pickups

Nice diagram.I wander is there a way to make a 3 way switch in the tin? I than can get 1 cord going into my amp and switch between piezo/mag/both? Or am I asking to much?

problem with a 3 way on the tin is bending over to set it.

consider stomp switches.  ive seen dp3t ones on ebay at 3 for $10.  one of the other throws can light up a led, you can probably piggy back power for those from the preamps battery

replacing the piezos output jack with a switching jack enables you to sum the outputs when you dont put a cable in that connector
