Good morning all! I am a Spector fan through and through! I am looking into buying a new 4 string and was wondering the thoughts of people who own both a Spector USA bolt-on versus the Euro neck-thru I love the idea of neck-thru construction, but when I asked Spector to customize a special order, they said they do not offer most of those upgrades in the Czech factory. i.e. Bart pickups, OBP-3, hipshot hardware etc. I looked online and it seems like the US bolt-on's have every option that I want in a four string without having to have it modded aftermarket. I know that a US Spector BO bass will be an exceptional instrument, so why do I feel like I am taking a step back with a bolt-on neck instead of neck-thru construction?? I need your help Spector enthusiasts!
