I think of the wave envelope as the area occupied by the string while it is vibrating, (I think I got the term from Chris Robinson). But what I was refering to was that the area just beyond that. I learned somewhere that if a hammer checks too high, (especially in the bass) the hammer head can interfere with the air currents coming off the string, so if you increase the checking distance, the tone may improve. You are saying that raising the backcheck improves the tone. So what I mentioned is the opposite, but my point was to question whether the position of the hammer head when in check is having an effect on the string. Clear as mud? Gordon Large, RPT Maine
