It is attached to the bridge and has a short gooseneck. Preamp: mandatory several preamps (dual channnel) availableįishman offers a small microphone from Crown as a supplement to or budled with the BP100. The sound can be adjusted by turning the wheel some degrees. Preamp: optional several models (single/dual channnel) availableĮncased inside an aluminium height adjuster wheel of the bridge, which are very easy to install of you already have adjusters with the same thread in your bridge. ![]() This pickup is offered since 1979, and has been sold over 75,000 times so far, as Larry Fishman states. (Alternatively, the piezo elements can be glued on.) Two piezo plates are stuck to the top side of the bridge by means of two metal pegs. Preamp: optional several preamps (single/dual channnel) available 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. mixing console) is mandatory for the studio model. While the aktiv can be used on balanced or unbalanced inputs, a balanced input (e.g. ![]() The Bassbalsereit aktiv and studio models work with 7–48 V phantom power. Existing older versions can be updated by the manufacturer. For these models, a miniature preamp (sized 4 x 6 mm) has been built into the brass cone. If you turn this brass pin in the bridge, you can adapt the sound to your instrument.īesides 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. This pin is simply put into a conical hole drilled into the top end of the foot of the bridge. This pickup consists of a conical brass pin which is 4 cm long and as thick as a pencil. Inside the preamp there is a user mix control to set the balance between the bridge and the body sound. The 9-volt battery clip simply attaches to the tailpiece with Velcro. ![]() This attaches onto the two middle strings between the bridge and tailpiece. 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. 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. The system also includes a fixed, sharp-slope, high-pass filter for the elimination of handling noise from the signal. The preamp (“Statement Mixer”) has two individual mix controls, to preset two different sounds, and a footswitch to select between these sounds. ![]() The third transducer is fitted underneath the bridge on the bass side (using the string pressure on the bridge to hold it in place). Two transducers mount into the bridge, using non-adhesive cork shims: one on the bass side and the other on the treble side. This preamp can also be used with most any other piezo-based pickup, and will be a simple means to get transparent sound with an XLR output (so it works like a direct box.) The unit is powered by phantom power, so whatever you plug into must supply it.This pickup consists of three transducers of a new develloped elastic electret film. While it seems to be a pretty simple device, we suspect that Göran Ehrlund has carefully tailored the preamp's setup to specifically suit his pickup - it really does seem to sound better through the Ehrlund preamp than most others we've tried. It also properly buffers the signal for whatever you're plugging into.Įhrlund pretty strongly recommends that you use his preamp for the best possible results, particularly if you play arco. This preamp was designed to be used with the EAP pickup, and it features simple adjustments: a Volume Control, a "High/Low" Switch (Ehrlund recommends "low" for upright bass), and a Phase Switch for helping to reduce feedback or for switch phase to match a second pickup/microphone, if applicable.
