I have a Series I guitar from 1976 for sale.
 
It has recently developed a hum in the bass [neck] pickup, but the bridge pup and all controls work, so I assume it is a fairly straight forward fix.
 
It's listed on ebay.

Is this the Bass with the crack in the neck?

I believe this is a 6 string guitar that Barry spoke about in another thread.

crobbins is correct.
 
Not a bass, no cracks in the wood or neck.
 
Some finish cracking due to age, but no structural damage whatsoever.
 
Lots of Mojo!!!
