Has anyone had the chance to directly compare the Raven Labs PMB-II with the new D-Tar units? I have a PMB-II that's been just about perfect for a variety of my needs, until now. Looking for a unit with an XLR input for a mic, as well as 1/4" for pickup blending. Love to do away with the XLR adapter things when using my mic. I'm a doubler and have found the PMB-II to be great for electric bass, EUB and upright...would the D-Tar units compare tonally, construction-wise, etc?
