Its all in the details...

Warwick has a page set up for pulling details for one of their basses - by serial number entry.  It returns the details of the production date and the materials used.  The online version is usable for models made in 2000 and later.  Since my Warwick was built in 1989, I had to use their manual method - which is outlined on the same page.

In order to use the manual method, the following items are required in an email.
  - Model name
  - Serial number
  - Photo of the bass - front view
  - Photo of the bass - back view
  - Photo of the bass - of the opened electronics compartment
  - Photo of the bass - of the serial number

The results are emailed back to you.

All information I already knew but still cool they keep records of every bass they build. 

Plus, if I ever decide to sell it, I can point the would-be-owner to the site to verify anything I say. 

And no, I am not going to sell it.
