MT, DP
Type: magnetic
Mode: passive
Preamp: built-in, dual channel

Two Models available. The DP has the preamp sepparate from the pickup, which can be mounted on the tailpiece of the bass, or sepparate from the instrument. The ‘MT’ is a self-contained unit with both the coil and the preamp attached to the fingerboard. They have adjustments for each string so that one can even the output of the four strings. There is an onboard volume, pan, and tone. The mixer allows one to mix in a piezo transducer, and blend the two sounds.

Statement
Type: electret-film
Mode: active
Preamp: incl.

This pickup consists of three transducers of a new develloped elastic electret film. Two transducers mount into the bridge, using non-adhesive cork shims: one on the bass side and the other on the treble side. The third transducer is fitted underneath the bridge on the bass side (using the string pressure on the bridge to hold it in place). The preamp (“Statement Mixer”) has two individual mix controls, to preset two different sounds, and a footswitch to select between these sounds. The system also includes a fixed, sharp-slope, high-pass filter for the elimination of handling noise from the signal. In addition to the usual 9 V battery or regulated 12 V AC/DC adapter, the preamp can also be powered by 48 V phantom power.

D 1
Type: electret-film
Mode: active
Preamp: incl.

This system includes the same transducer type, but a more simple active preamp that is an all-in-one construction with the 1/4″ output jack. This attaches onto the two middle strings between the bridge and tailpiece. The 9-volt battery clip simply attaches to the tailpiece with Velcro. Inside the preamp there is a user mix control to set the balance between the bridge and the body sound.

Type: magnetic
Mode: passive
Preamp: dual channel, incl.

Like other magnetic pickups, this one attaches at the end of the fingerboard. With the preamp (passive; no batteries required), you can blend in the sound of an already existant piezo pickup. For bowing, the magnetic pickup can be muted by a switch.
Michael Zadow offers his pickups custom-made for your individual bass’ measurements for the same price.

Unlike other magnetic pickups (like Fender Precision-bass-pickups or Schaller), this pickup sounds more acoustically. For Rockabilly/Bluegrass slap-bass-players, the second channel is very useful to add a fingerboard piezo-pickup.

Also available for 5-string basses and cello.

Michael Zadow also manufactures the ze200 double bass combo amp.

At www.kontrabass-atelier.de, also available with the BassBall. This microphone mount can used instead of a gooseneck: just put it into the bridge arch (between bridge and top). Due to the ball shape, the capsule can point in any angle to the top. The distance from mike to top can also adjusted very easily.
