The conductor strips and wrapping give this pickup an amount of rigidity. It has a piezo strip between two conductor strips (hot and ground) and it’s wrapped in a (grounded) shielding tape to keep any nasty electromagnetic interference (EMI) away from the internals. This is what I refer to as a ‘rigid’ UST. Each operates on essentially the same principal - a piezo ‘strip’ is sandwiched between a hot and ground conductor and is shielded all around in some way - but how they achieve this is slightly different. More possibilities opened up for UST pickup design and, as things have shaken out, we’ve ended up with three main types.

Now it was possible to make a single element span the full length of a saddle slot. No more need for housings and individual elements for each string. Through the application of liberal amounts of “science” these boffins were able to make thin, flexible, plastic sheets that were essentially big, flat, piezo elements. Yeah, Science!Īround thirty years ago, men and women with high foreheads, wearing white coats, and carrying clipboards started doing weird things with various plastics. Careful positioning is more critical and they may not be ideal if your guitar has an odd string spacing. They work fine but, because there are six discrete elements, they can be fussy about placement - if each element isn’t directly under a string, you can easily have output imbalances from string to string. And this is what some USTs are still like, especially at the budget end of the market.
