    Sorry, but maybe being a bit dim here but what is a Piezo bridge/ pick up?

    Keep reading about them but not really sure what they actually are and how do they differ from other types of pick ups. Done a search but found no definitive answer

    It's a special type of pickup that's in the bridge.

    Is it a smaller version then of a standard pick up? does it give a much different tone to a 'standard' pick up positioned by the bridge?

    It is a totally different animal.

    It's a crystal, that emmits electric current when under physical pressure. The electric out is proportional to the physical load.
    Hence, a vibrating string makes vibrating pressure on the piezo elements, which emmits a "vibrating" current.

    No magnetics etc would let the string vibrate more naturally, giving better sonic representation. OTOH, the piezos have a rep of giving a lot of highs - being "brittle".

    Just a beginning of a good answer, but it's a start...

    Thanks Suburban. Great beginning!

    It's starting to make sense now.
