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 transduced 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.

Here's what the player's think.
Double Big Twin:
John Burns - "I wanted to let you know that I am very happy with my recent order. I replaced my Fishman piezo with the K&K, and there's really no comparison. The K&K is much more natural sounding and it was cheaper, too. The installation was simple and your instructions were clear. I was just about to fork over half a grand for a better pickup than my Fishman when I came across your web site, so thanks! You saved me money and I am quite satisfied. I don't have the best bass in the world by a long shot, but it sure sounds better with the DBT."
Andy Fuchs - "The Double Big Twin is the best upright bass pickup bar none. Lots of output, clean detailed sound, reasonable price, and easy installation via doubleback adhesive. Mounts right on the bridge and sounds great."
Tom Buckley - "The sound... I love it! I left my venerable BB (Barcus Berry) on in order to A/B the two. No contest. The K&K is extremely clear w/a very complete and flat response across the desired frequencies, and a nice little oomph in the low-mids---makes for a great-sounding A string. I especially like the lack of emphasis in the "finger-noise" region. I find the K&K a bit less microphonic than my BB or my Shadow... I can turn up the preamp gain w/out a lot of increased finger noise, and the clarity jumps right out. It's nice not to have to worry about distortion (not even close) the way I did when I used the Gage (Realist) pickup. Judging from my headphone test, I'd call it more "natural-sounding" than the Gage...(Realist)"
Larry Dolamore - "My impression so far is that I'm getting a warmer, more natural tone from the K&K than from my Fishman pickup.... I believe than the K&K pickup is an improvement over the Fishman, it certainly sounds less electric, and I'm happy with it. The big test occurred Saturday when I played it at a job. I have been playing the bass through my amplifier a lot this past week, tweaking this and that to hone in on my preferred sound. I was able to achieve a sound that I liked. I've also found that, at higher volumes, the K&K pickup is less prone to feedback than the Fishman was. The overall volume at the job was moderately loud and I experienced no feedback. My Fishman used to feed back easily on an open A, unless I adjusted the amp settings and then the sound quality suffered. This problem did not exist with the K&K. The bottom line (bottom line! I'm killing myself) is that I like the K&K and find it superior to the Fishman in tone and feedback busting capability.
