Wapin can be installed while the piano is strung, but you'll need to lower tension/move strings about to accomplish that. This has the most dramatic effect compared to others,unless you're going to put in a new board. but takes some doing. By all means do everything you know about tone building before you Wapin or other options. For me these next mods were "subtle. " treble resonator from Pianotek Riblets The above two have some subtle immediate effect, but also after a day or so, the change seems to come up a bit even more. The treble resonator can be "tuned" slightly, if that's the problem. (Stiffness). How to know what to do when, there's the rub! I've read some accounts of adding mass and those procedures have not been made too public yet, but you can experiment w/small vice grips on the back bridge pin in various areas to see if adding mass will do anything to enhance the sustain. Sometimes it filters/or dampens. Some people attach weights to the back of the soundboard/ribs and some move the treble wires aside, drill out the bridge, instert a small weight, and then cover it over...replace the strings. You need to be sure, that where you put them does not damage the bridge, or contact the strings. Several in a line, increasing or decreasing, depending on where you go. Someone really needs to get a proper procedure written up. Maybe they have. There probably is an "order" of preference as to which mods you should do in which order. Others can speak to that. Just throwin' some ideas out there. Richard Adkins Coe College -------------- next part -------------- An HTML attachment was scrubbed...
