Feline guitars have been a proud stockist of JJB pickups for a while now
Made In USA
We have found them to be as good as anything  else we've tried and more cost effective than the system from K+K Sound.

Prestige-430c pickup - 15mm size

The Prestige-430c is passive system for classic guitar, with four pickup heads and an endpin jack. It is well suited for both nylon and steel string classical guitars.

These are built using 4 very high quality 15mm piezo's. These can be used with or without a preamp with fantastic results.

It utilizes four surface mount transducers to deliver a natural reproduction of sound from your classical guitar. This results in a very wide frequency range and very natural reproduction of sound. The four-piezo configuration offers a few advantages over other piezo systems. Having four piezo’s affords you the opportunity to place them at four different points on the soundboard thus resulting in an improved dynamic range due to the fact that they transmit the resonance found at several points.

These special surface transducers are under less pressure than under saddle pickups thus decreasing the likelihood of them transmitting a percussive or harsh sound. Each piezo is designed to pick up the resonance found in a significant amount of the soundboard. These do not "fade" or distort at high volume or with high-power systems. The highs are crystal clear while the lows are what they should be, low!
