Hey Sheldon,
I noticed that Mike Lull has launched a t-bird that closely resembles the 64 Thunderbird. The bass has an improved bolt on neck, but the pickups are very accurate renditions of the 64 t-bird. This may be fantasy, but what if you could make these available with your jazz neck (upside down with a super t imprint) and the Dingwall chrome jazz bass bridge???
If you were using Lull's body assembly, this could be cost prohibitive, but I had to ask. You can see the bass on Mike's website if you have not seen it already at NAMM.
Thanks!
