Chrome plating is the only thing I could see from Custom quote generator. I know that Series II adds some nice wood working upgrades (more decorative laminates etc) I just didn't know if Series I received similar treatment.
Cocobolo and 5A Quilt is very expensive upgrades now, it is difficult to make up that much cost difference in just decorative laminates or other minor upgrades. Maybe there's something that I don't know about, that's mainly what this post is about.
And I agree with you on SI to SII upgrade. It is very small charge, you might as well do it while you're spending over $10k.
Right now, I'm looking at many options. I can upgrade my electronics on my current bass, or I can sell it, and build me a new one. New one would have to be less 'flashy' as far as options go, but ever since I played SC signature at store, I am extremely attracted to short scale basses. And used SI/SII short scale basses are pretty rare, so my options are limited.
If I were to order a new one, it would be SI (with SII upgrade) with short scale, Standard body w/ Omega cut and pistrl grip horn.
