hi, i just installed a custom version of the miracle mod, by adding bumps
it feels really light compared to how it was. there is little hammer bounce now. whats more amazing is it took me about an hour. i highly recomend this mod to anyone with the same action - mine is a '77 with plastic hammers with felt on the bottom, i left the felt on the bottom of the hammers, and put the bump on the edge of the pedalstal, it plays amazing now, it also reduced the key bounce.
next i am going to replace the grommets, and maybe extend the 2nd to top tip range down to middle C!!!!!
