I felt the same way. My experience is similar. The first Spectors I played were Euros, the necks on them were pretty consistent. Chunky, but with traditional round C type profiles. I could have gotten used to them eventually, but I had Phil Jacoby shave them down for me. A few months down the line, the US Spector bug hit and hit hard. Spector Godfather Sam Cerami got me an insane price on a NOS Forte-4. Back then he was known as the Spector Pimp! Before the bass arrived I had ordered a US 9V circuit, those were the good old days LOL. When the bass arrived the first thing I noticed was that the neck was substancial. Technically speaking it was not huge front to back. The reason for this was that the neck had a flat profile. Like a squished D. I could have gotten used to it, but when you have one of the best luthiers on the East coast close by, why bother? Phil Jacoby to the rescue once again. Most of the material that he removed was from the "shoulders". It's not crazy thin now, but it is crazy comfortable. I understand that the newer model Fortes are beefy but rounder than the earlier ones.
