The design features common to all PiezoBarrel pickups are listed below.
The PiezoBarrel 'Wood' is currently the most popular PiezoBarrel pickup. It was designed initially for clarinet but is also popular for a variety of instruments and popular with experimenters. Generally this pickup is chosen for it's dark sound and is particularly suited for the clarinet or bass clarinet though it is also popular for Alto and Tenor sax when a rich mellow sound is desired. The 'Wood' can also be used for trombone and low brass.
The PiezoBarrel P7 is a bright sounding pickup that is intended for the saxophone family or for clarinet where a bright airy sound is preferred.
The PiezoBarrel P9 has been developed as a trumpet pickup from the ground up. It is very bright compared with the PiezoBarrel 'Wood' and a little brighter than the P7 and produces a natural sound on the trumpet without any EQ. The P9 makes brass instruments sound brassy and works with a variety of brass instruments - not just the trumpet.
The PiezoBarrel R1 is is similar to the PiezoBarrel 'Wood' but designed for the recorder. The recorder usually only produces a weak signal in the low register and any attempt to produce a stronger note results in the sound becoming unstable as it starts to overblow. For this reason, the R1 was designed to have a non-linear frequency response that increases the bass frequencies and thus strenghens the low register.
