    Its cheaper to build your own. There are a few ways to construct contact microphones.

    Take a look at this video:

    (if you don't have a glue gun, you can probably find another way of securing the transducer, maybe some gum-like strong blue tac or other glue)


    I am the thing that goes bump in the night...

    For PZM (boundary mics)- you could use the Primo EM172 capsules and wood for the surface.
    for contact mics- buy a few piezo elements from farnell/Digikey/conrad and use Susanne Grunewald's excellent guide for constructing them:

    I also really recommend building a simple "impedance buffer" for your piezo's, because they have very high impedance, much higher then your average mic preamp input. Using such a buffer between your piezo and preamp really improves the bass response and overall sound. The buffer I built myself is based on the following guide:

    ok pretty simple - like how he deals with the cat- I have that problem a lot... actually a lot of my quiet recordigns have quiet cat snores in ......

    nice tips - yes the pre-amp...

    I have a nice street not so far from me that has lots of electronics shops...

    thanks
