I recently installed a Wittner tailpiece when I discovered the afterlength of my strings was too long. In the process I had to cut my own tailpiece wire with 1/8 aircraft cable and aluminum crimp sleeves. I had to cut the wire quite long as the bottom of my bass is fairly large. This left the tailpiece floating in the middle between the bridge (about 5" away) and the saddle (about 3" away). After I installed the Wittner tailpiece I noticed a distinct improvement of tone and playability of my bass. The old ebony TP weighed about 10 oz., the Wittner (with extra long cable) about 6 oz. Then I saw the thread on the Marvin wire TP. After reading that and noticing the improvement taking 4 oz off the TP made, I decided to try to make my own wire tailpiece. It was quite easy and only cost $8 for the materials (2 piece 1/16 aircraft cable - each 48" long, 4 round single sleeves and 11 double sleeves). The only tricky part of making it is finding a large bench vice to crush the single sleeves so the cable is totally secure. Oh yeah, and installing it was a major PIA. I made the part that holds the string ball a little lasso with a loop and double sleeve (uncrushed) then a crushed single sleeve on the very end. This way the loop can be cinched up to hold the ball. I put an array of double sleeved where the cables go over the saddle to keep the cables together and to eliminate the string tensions from pulling on each other. The G-string cable goes around the endpin and is attached to the C-string and the D-string is attached to the A-string. Wow, what a difference the wire tailpiece has made on the sound of my bass. The notes speak much quicker and are louder. The fundamental is stronger and the upper partials are more present (ie. it sounds brighter and deeper). The strings are easier to push down and the sustain on pizz notes are longer. The tailpiece rings on a G so I will have to put some kind of dampening agent on the vibrating wire. Maybe a lead fishing lure! I highly recommend using a wire tailpiece! Pictures to follow at some point.
