[quote name='JoshJ' post='988431' date='Oct 14 2010, 09:07 PM']I've been thinking about doing this, got to be good if it saves us £100 or so on a "proper" pickup, and I've even seen people suggesting they can sometimes be used without a preamp which would save us another big lump.
One of the best sets of instructions I've seen is [url="http://fittell.id.au/piezo/"]this one[/url]. He suggests putting it under the bridge foot, but if you do that, you need to use the layer of cork so the piezo can still move, and then I can imagine you having a lot of fun getting it to sit nicely.
From what I've read so far, the "something" you've forgotten could be:
Piezo needs to stretch so don't fasten it too tightly (I guess), but obviously it needs to make good contact with your wood .
Keep the wires (and the cable to the preamp, I think) short and secure them as well as possible because movement in the wires will be picked up in the signal.
DON'T solder anything directly onto the piezo terminals because you can melt the piezo film.
And most important of all: Take lots of photos and write everything down so I can copy off you and learn from any mistakes you make
Good luck!![/quote]
I'm going to start basic and adjust for problems when I get them, my first run will involve masking tape on the bridge.
