I am now the proud owner of this S-500

This is my first Strat style guitar and I'm glad I went straight for a G&L. I'm quite impressed by the feel of the neck.
However, it's a bit of a mystery to me has the electronics are not those of a S-500:
- There's no mini toggle or push/pull pot
- It has standard tone knobs (tone 1 : controls treble on middle pickup, tone 2 : controls treble on neck pickup)
- Hence, there's no PTB (Passive Treble and Bass)
- The pickups have non ajustable poles and are noisy on single coils
The answers I've found with the documentation and by searching this forum:
- Serial : CLF42865 (plastic decal)
- Number on the inside of the back plate : 6072 629
- Made in USA with COA
- Created : between June & August 2006 (if I compare S/N with others in the registry)
- Bi-Cut Neck that feels Plek'd and seems to be a No 3 60's style oval (no shoulders, not flat/pointy in the middle)
- Sperzel locking tuners
My questions:
- Is it a custom job : An S-500 with a Legacy pickguard & pickups? If it is, it doesn't start with CLF0 because it was built in mid 2006.
- Are the pickups still MFD? I'm getting a lot of noise on singles, but this is my first single coil. My rig is usually quiet.
- Is the body Alder? I've looked at types of wood and grain patterns online and it doesn't seem as agressive as Ash or as murky as Basswood.
- Is the neck indeed a No 3 60's style oval?
I'm reticent to check the neck/body for dating as I've just gotten a fresh setup and from what I gather G&L stopped stamping the necks in 2005.
If it is an S-500 with a Legacy pickguard, that doesn't make much sense to me. Why not just get a Legacy?
Craig, if you could get the specs on this one, I would really appreciate it. I'd like to know what I have before considering modding the electronics.
Thanks all for your input.
