JON! Spoilsport! Aren't the strings supposed to buzz on the v-bar? Seriously, though, folks - Jon has hit on something, pedal geometry. Before messing with the spring (on any piano) it's probably appropriate to check and be sure that the trapwork is functioning _properly_. In most pianos (newer ones, anyway) this means just checking for freedom of movement, broken parts (did somebody manage to drive that nasty capstan that's supposed to limit travel all the way to Cleveland?), etc. On other instruments, there are places which may have opposing involuted curves. If these actions are worn/misinstalled/etc, and the curves "overcenter" each other, the leverage then works against you and not for you. (Check out Chris Robinson's action seminars.) "OK, wise guy", I hear you saying - "and just how do I check for that?" With everything in place, (properly) tightened, get under the piano and _slowly_ work the pedals, and then the trapwork separately. If you see/feel/otherwise notice points in the travel of the mechanism where things seem to either bind, or slowdown/speedup, chances are you have a geometry problem. A few moments spent in this kind of diagnostics can save an ocean of trouble later. It does, however, sound like this is not the problem for Marcel. More meanderings of a demented mind... Best.
