I recently discovered the joys and advantages of Brendan Power's Power Chromatic tuning. Slaved away in my workshop and cobbled some Seydel reed plates with a lower G root using my Backslider design. Doing this allowed me to play Take Five at the bottom end of the harmonica. https://www.youtube.com/watch?v=fwJyiHc0WvwBest Regards!David Pearce
