The Double Big Twin is a four-headed double bass transducer developed specifically for jazz bass players.
It harmonizes very well with jazz bass, because its transmission band includes very high and very low frequencies.
The high frequency translation ensures a clean amplification of the finger attack with the picked bass.
The low frequency translation refers to a desired very bassy sound picture.
Each string of the double bass is picked up separately with the Double Big Twin.
This results in an extraordinary balance of sound to accommodate even the pizzicato playing mode.
Double Big Twin is easily mounted with the supplied double-sided adhesive film and doesn't require modification of the instrument itself.
This adhesive film has been selected carefully because it proved to have excellent qualities for sound transmission.
The connection jack is held in a special attachment clamp to be mounted at the A and D strings between string-holder and bridge.
We highly recommend one of our K&K preamps for impedance adaptation and pre-amplification.
No batteries required: The output level of this passive Pickup is enough to be processed directly from the mixer or amplifier.

Extensions of the System

... are usually very easy to perform because we offer special expansion kits that are customized to your installation. If you don't want to afford a more sophisticated System yet, you can upgrade at any time, without giving away money.The following extensions can also be found under the "Accessories" tab.With existing Systems, the Pure can be combined to provide even more sound variancy.

Preamps, Volume Control [»] show/hide
- A volume control can also be installed later. This is feasible in general without soldering. The controller is passive, therefore, requires no battery. He can only reduce the level but, as it does not have a preamp. Suitable for all K & K Pickups (and possibly other manufacturers), but not for microphones with phantom power (e.g.: Trinity / Meridian). We also offer a variant of the Pickup, in which the regulator is already integrated.
- The Pre-Phase preamplifier is installed in the body. It has a volume control and a phase switch. Operating with a 9V battery.
Suitable for all K & K Pickups (and possibly other manufacturers), but not for microphones with phantom power (e.g.: Trinity / Meridian).
We also offer a variant of the Pickup, in which this is already integrated preamplifier.
- The Pure Preamp preamplifier is a small box that can be externally attached to the strap. It has volume and tone controls.Operating with a 9V battery. Suitable for all K & K Pickups (and possibly other manufacturers), but not for microphones with phantom power (e.g.: Trinity / Meridian).
- The external preamplifier Pure XLR is slightly larger than the Pure Preamp and offers additional features. It can be operated by a 9V battery, and an XLR cable, which holds a phantom power available. So the Pure XLR also serves as a DI box to connect over long distances with the console. The volume and tone controls as well as the phase switch is directly accessible. Suitable for all K & K Pickups (possibly other manufacturers), but not for microphones with phantom power (e.g.: Trinity / Meridian).
- The Dual Channel Pro Preamp is a small box that can be externally attached to the strap. It has two channels, a volume and tone control (internal) and two controls for adjusting the volume of the two sound sources. Operating with a 9V battery.
Suitable for all K & K Pickups (and possibly other manufacturers), especially when two sources available (e.g.: Pure and FanTaStick), but not for microphones with phantom power (e.g.: Trinity / Meridian). This preamp is it both in a version with stereo output as well as in a 2 x mono version.
There are also versions of this internal preamplifier, which are installed in the body of the guitar. We also offer variants (see Powermix) of the Pickup, in which the internal preamp is already integrated.
- The Trinity preamp is a small box that can be externally attached to the strap. It has a volume and tone control (internal) and two controls for adjusting the volume of the two sound sources.
Operating with a 9V battery. Systems suitable for all K & K Trinity and Meridian.
There are also versions of this internal preamplifier, which are installed in the body of the guitar. We also offer versions of the Pickup, where the preamplifier (external or internal) as well as the Trinity or Meridian microphone are included.
- The Quantum Blender Preamp is a professional tool to suit highest sound quality, best usability and great features. It has a volume, gain, tone control and phase switch for each of the two channels. Operated with supplied Euro AC adapter. Suitable for all K & K Trinity and Meridian Systems and possibly other manufacturers, especially when two sources are available (e.g.: Pure, FanTaStick, Trinity ...).
We also offer versions of the Pickup, where the preamplifier (external or internal) as well as the Trinity or Meridian microphone are included.
- The progression tube preamp is an advanced device. Handwired and measured the two tubes do their "warm" service. It already has almost something of esotericism. The volume and tone controls as well as the inverter circuit is directly accessible. Suitable for all K & K Pickups (other manufacturers), but not for microphones with phantom power (e.g.: Trinity / Meridian).
Microphone Extension [»] show/hide
With a specially designed condenser microphone, you can give your sound more lively.
- The Trinity microphone can be easily (with a Pickup already installed (e.g.: Pure, FanTaStick be combined etc.). It is attached with Velcro holder in the body and has a gooseneck, the one to facilitate optimal positioning and the resulting therefrom sound variations. For this microphone phantom power is required so that you (a corresponding preamplifier for(e.g.: Trinity, Quantum, etc.) need. An internal version of the preamplifier is also available.
- The Meridian Microphone can be easily (with a Pickup already installed (e.g.: Pure, FanTaStick be combined etc.). It is attached with Velcro holder in the body and has a gooseneck, thus to facilitate optimal positioning in order to increase sound variations. The bracket can be easily removed and another instrument to be adapted so that you can multi- Instruments only need one System.For this microphone phantom power is required so that you (a corresponding preamplifier for(e.g.: Trinity, Quantum, Meridian, Meridian Pro etc.) need. For this microphone phantom power is required so that you (a corresponding preamplifier for(e.g.: Trinity, Quantum, Meridian, Meridian Pro etc.) need.
