I just bought a Martin D-42 custom shop model. Its basically like a D-28 Marquis but with the 42 style inlays and a torch headstock inlay. It has the typical vintage style through saddle FWI. The guitar came with a Highlander IP2 Dual System installed. So its the IP2 undersaddle pickup and Highlander mic all hooked into IP2 Preamp and Stereo jack. I pulled out my stereo cable and hooked this into the sound system at my church straight in and the results were breath taking!!! By far the best plugged in sound I've ever had and I've had some great guitars with good systems but this one kept every thing I like about that Marquis tone and amplified with beautiful results!!!!!! Pricey pickup but well worth the money!!! PS The guitar sounds great unplugged as well.
