Fausto, Welcome to the list! It's difficult to tell just from your description, but I would guess that you have either loose wrappings on the bass strings or a termination problem. My immediate guess would be wrappings. The best remedy for that problem is to replace the two strings. It is also possible for the bridge pins to be buzzing in the bridge. Placing a hammer shank against the pin and tapping it down into the bridge should seat the bridge pin into the hole and eliminate the buzz if this is the offending part. You can also look in the archives concerning string and bridge pin seating for an in-depth discussion. Hope this helps a little, Allan Allan L. Gilreath, RPT Gilreath Piano & Organ Co.
