AJF's had a conventional ebony bridge with a composite tailpiece and pickguard/finger rest. The Bigsby vibrato tailpiece is another option. The ES-355 was available with a Vibrola vibrato unit or a Bigsby vibrato tailpiece. The new Epiphone "Trem-o-tone" adjustable vibrato tailpiece is introduced. The vibrato tailpiece was the floating type with a locking device. This was simply known as the "Fender vibrato tailpiece", or sometimes the "Fender steel vibrato". The tailpiece and endpin are found in the lower part of the cello. A second prototype was made, adding a vibrato tailpiece and a metal nut. His Gibson 335TD has been changed from a Frequensator tailpiece to a Bigsby. Another type of B-Bender is activated by the picking hand, like the Bigsby vibrato tailpiece. Another transitional design is the parlor guitar fitted with a floating bridge and tailpiece. It has a floating bridge and a metal tailpiece. The tailpiece is attached to the bottom of the cello. It featured a single pickup, volume and tone controls and a rudimentary bridge/tailpiece. They were stretched between the yoke and bridge, or to a tailpiece below the bridge.
