The 1959HW has ˜Plexi' DNA running right through it. It has the classic tonal notes of those early ˜Plexis' which, being non-master-volume, when cranked overdrive the power valves, producing those sweet, highly responsive, harmonically rich tones, with chest-punching projection. And to make the 1959HW as authentic as possible, Marshall used original thickness, original pitch matrix, point-to-point tag boards. With the transformers being an integral part of the ˜Plexi' sound, they also worked closely with Dagnall to duplicate the later-era ˜Plexi' power transformer. The result is that the 1959HW is the ˜best of both worlds' because it takes the best features from early ˜Plexis' and later ˜Plexis' to produce a truly awesome reissue..
