Thus far, only three fretless 12-string (4x3) basses have been made.

Custom 2010 Wishnevsky Left-Handed 12-String Bass
|
This bass was built by Michael Sparacino in Minnesota. Starting with a body made by Steve Wishnevsky using a 5-string bass neck blank, Michael created this first-ever fretless lefty 12-string bass. The bass has a cherry body with a rosewood fingerboard. Neck through body construction; the neck is 5-ply with a truss rod. Michael writes, "I've got a 4-string fretless from Wishnevsky and am addicted to the woody sound. I've got that in spades with this 12ver. I went with through-body to optimize the wooden sound." |

As to the electronics, there is a single EMG passive pickup with a volume control. The compensated wood bridge was salvaged from a Harmony H-22 bass. "The intonation is surprisingly good given the wood bridge", says Michael. |
