I have a very heavily-wooded Romanian bass that also lacks acoustic pizz volume and arco response, but has good pizz sustain. I put a Marvin tailpiece on it, as a inexpensive gamble/experiment.

While the Marvin certainly improved the pizz and arco notes' clarity, evened out the registers, and eliminated wolftones, on my particular bass, the benefits are relatively minor, in terms of volume, pizz or arco.
