The flimsy, thin, original tailpiece on my friend's DM1 is now so bent, from string tension, that is is touching the top. The tailpiece on my own DM1(now sold), showed the same problem, just not as severe. The metal stamping is apparently too thin to resist the string tension. The variety and cost of available upgrades is confusing: can anyone who has made this upgrade suggest the least pricey improvement? One gets what one pays for, sure, but, any suggestions?
