Besides the passive version, available for 15 years now, two improved active versions has recently been launched by Michael Schäfer, who took over the manufacturing from Willy Balsereit: the aktiv and the studio model. For these models, a miniature preamp (sized 4 x 6 mm) has been built into the brass cone. Existing older versions can be updated by the manufacturer.
The Bassbalsereit aktiv and studio models work with 7–48 V phantom power. While the aktiv can be used on balanced or unbalanced inputs, a balanced input (e.g. mixing console) is mandatory for the studio model. For the aktiv model, a DI box with phantom power supply is available, so it can easily be used with all kind of bassamps and mixing consoles.

LiveBass H-Clamp (microphone holder)
With H-clamps, practically any microphone can be mounted on double basses (or cello/guitars/…). Inspired by the design of the clamps used at the luthier’s workshop, they H-clamp is mounted to the ribs. The choice of the edge of the body as the fixing point for the H-clamp is important for several reasons. It is convenient from the perspective of positioning microphones unobtrusively, but more important, the edge is the strongest part of the structure and the point at which clamping has least effect on the resonances of the sound box’s panels. The H-clamp can therefore be tightened very securely and yet have no discernable impact on the sound of the instrument. The H-Clamp’s components are machined from aerospace grade materials by an experienced manufacturer of high performance components for aircraft and aeroengines.

The Polytone system utilizes a piezo bridge transducer in combination with a condenser microphone. The bridge transducer mounts in the treble wing of the bridge under the ‘G’ string, much like the ‘Underwood’. It is a square-shaped piece of wood with the piezo inside. The mike is mounted in the center of the treble-side ƒ-hole, and is a square-shaped wooden unit with a red-button attached, called the “feedback eliminator”. It disconnects the mike from the sound to reduce the feedback. The unit does not have panning capabilities, so there is no control over the mix of mike and transducer.
The Realist (Original)
Type: piezoceramic
Mode: passive
Preamp: –
The Realist acoustic transducer was designed by Ned Steinberger in collaboration with double bass luthier David Gage, and has quickly become very popular.
Ned Steinberger on the development of The Realist: “(…) The first is finding the right structure within and around the piezo crystal to respond optimally to the acoustic resonance of the instrument itself. (…) Second, placing the transducer under the foot of the bridge puts it exactly were the sound is transferred from the strings to the sound board. This is definitely where the action is, and the rich, powerful response, both pizzicato and bowed, testifies to this simple fact. (…) The copper foil sandwich construction is the third key element in the system. It provides total shielding to eliminate hum from light fixtures and other electrical or radio interference. It is flexible enough to conform to the curve of the top of the instrument, so that the full pressure of the bridge is concentrated evenly onto the piezo surface (…)”
The Realist is endorsed by Christian McBride, George Mraz and Michael Moore.
This pickup can be found factory installed in the Eminence portable upright basses.
The Realist “Wood”
Because it is made of wood, the element will not have any chance of marking the top of the instrument on to which it is installed. Less darker sound than the original Realist, although texture is very slightly compressed.
