One of the most likely Walnut Strat shows is St Paul 2/17/73. There were a lot of technical difficulties for Jerry and the whole band in the first set. Jerry has guitar troubles in the middle of Wharf Rat and again during the lead break after the Streetcats verse in Looks lIke Rain... For the rest of the show, it definitely sounds like Jerry is using a guitar with a tone that sounds more like Gaelic Park than any of the Europe 72 shows.
Also, Roscoe Maples was the debut of the proto Wall and elements are seen again at the Champaign shows. The noise cancelling mics were not used at one of the shows where Jerry was using the Walnut AND wearing the Nudie jacket. It's my belief that they skipped using the proto WoS components between 2/9 and 2/19, the gear was sent straight from Palo Alto to Chicago and they just used the 72 sound system for the 3 shows in between. Jerry's tone changes after 2/19 and this may have been the result of a switch to a different Twin than he was using prior.
