It was January of 2005, and I had arrived in Anaheim for the first day of NAMM. My very pregnant wife and 3 year old daughter had just just left for Disneyland and I was happily striding through the lobby of the Marriot on my way to the convention center conveniently located next door.

This was a big year for keyboard players at NAMM. The controversial megabeast OASYS was being debuted at the Korg "booth", while Alesis snuck in a phenomenally-featured, extremely affordable Fusion (now essentially defunct).

Personally, this was a bass fanboy's dream year. I met and got to play the fine creations of Jens Ritter, Michael Tobias, Zachary Vex, Emmett Chapman, and Carey Nordstrand, just to name a few. I also met many of my colleagues from the Bass Player magazine's forum for the first time at this NAMM: JeremyC, Bumpcity, Adrian Garcia, knucklehead, El Whappo, etc.

But, oddly enough, the thing that really has stayed with me from that NAMM show was Behringer. I walked into that booth and immediately noticed a giant display wall of guitar effect pedals. The audacity of Behringer was breathtaking. This wasn't an example of reverse engineering a circuit board. This was a wholesale cosmetic ripoff. Every pedal on that wall was a direct visual ripoff of either a Boss or Electro Harmonix pedal. You could make a (very weak) argument that the pedals modeled after Electro Harmonix products were only "in the style" of their progenitors. But the Boss clones? The only thing that visually separated them from the real thing was the space between letters.

Someone must have shared my opinion of infringement, because by the time they actually shipped, they looked nothing like Boss pedals.

From Behringer's site:
Bass amp modeling, direct-recording preamp and DI box all rolled into one!

So much more than a mere DI box, the BDI21 is also an analog modeling bass preamp/stompbox. We give you authentic V-TONE modeling technology capable of dialing up big vintage tube tones, funky slap sounds, crunchy distortions and everything in-between. You’ll get a truckload of great amps in a single stomp box—from traditional bass amps to modern overdriven amp tones that would typically require a multitude of effects units. Authentic tube emulation circuitry can be mixed with the direct bass signal via blend control. Use presence control for definition and upper harmonics or rely on an ultra-musical 2-band EQ specifically tuned for bass guitars. Use the BDI21 either for direct recording output with tube emulation or as a standard active direct injection box in bypass mode. The output is laid out on ¼' TS or balanced, gold-plated XLR connectors. A ground lift switch eliminates typical ground loop problems, and it runs on a 9 V battery or a DC power supply (not included).

Is it close to emulating the Sansamp BDDI? You'll have to read the project participants' journal entries and listen to their sound clips to make that determination. By the way, I ended up buying a used one for $19.00.
