All well and good but it misses the point. The experience of players that overblow is valid. Blindfolded or not. If Winslow tells me that the new ZA5 MS harps overblow more easily than the original Big Rivers it's useful information. As any player that overblows knows, the harmonica is at least half the battle. Set up of the harmonica can also have a lot due to with the overblow capabilities of a given instrument as can design. Lee Oskars being a good example of a harmonica design that doesn't facilitate overblows. In talking to Richard Sleigh, and Joe Filisko they both confirmed that some reeds just won't adjust and have to be replaced.
My point being that expert opinion based on actual real life experiences is an excellent method of learning. Yes experts are often wrong but so are engineers. Wasn't that pedestrian walkway in Oklahoma designed by engineers? I don't recall Winslow espousing the virtues of Hohner ZA5 alloy. He merely repeated Hohner's information for the list. What is clear from Winslow's post is that there has been an improvement in the quality of some Big River MS Hohner harmonicas. He has several. It is his belief that the ZA5 designation denotes the improved models. What needs to happen now is for the sample size to be increased. I've got several on order and I'll give them a try. Perhaps others will and maybe we'll all pass the test results on to the list. And try as I might, like it or not, no harmonica marked ZA5 that won't overblow because it's a piece of junk is going to improve my ability to overblow the damn thing just because I believe. fjm
