Does the old DTAR pickup = Wavelength Duo ?

Seymour Duncan lists the wavelength Duo as there mic + UST pickup system. I think I recall that's the same system as the DTAR that Guild used. Am I correct?

I got an Amazon gift card as a gift, and I always wanted to stick one of these in either the F47R or the D-55.

I believe it is the same thing as the DTAR multi-source. If you are buying one note that they make a nylon and steel string version. I believe the only difference is the size of the control panel. If memory serves me I think I read of issues where the larger steel string panel may not fit in between the bracing on certain guitars. So, take some measurements.

The SD Wavelength Duo-Steel and the former New Hartford used D-TAR Wavelength Multi-Source seem to be the same, they even used the same picture and Photoshopped the label and deleted the D-TAR on the soundhole board!

As the board shows: "Designed by Kevin Beller", who works for over 40 years for SD and is VP of Engineering.

And.... if you are not a fan of undersaddle pickups then SD also has another dual source called the Mag Mic SA-6 (horrible naming) which combines a magnetic soundhole pickup and omni-directional mic.

I came back to this thread and checked out some video reviews. I was kinda' expecting the mag Mic to be able to be only mic or only magnetic pickup and then blend each other, but the magnetic is always on. You just add more mic in with the blend. Still, some of the demos are pretty good. I wonder if the tone varies with the metal type of the strings?

Kevin Beller may have designed the PCBs, but the pickup and basic preamplifier circuit was concieved and designed by Rick Turner, the famous luthier who helped form Alembic, and later Renaissance guitars, and who is (was?) a luthier that is very highly regarded. He did a lot of the fundamental research that went into what was the the DTAR, and now the Seymour Duncan, acoustic pickup line (that is, the non-magnetic pickup type). He is the one who figured out that the famous piezo "quack" or rubbery sound of the piezo pickups of the day was related to preamp input overload, and then went to the 18V power supply (derived from two 1.5V cells that are stepped up by a DC-DC voltage converter). The T in DTAR stood for Turner, as in Rick Turner, the full name of DTAR being Duncan Turner Acoustic Research. Duncan paid for the research, Turner did the research, and Duncan built and sold the resulting products.
