I have one of these. I bought it about 2 years ago when it looked like this - (bad refin)
I had it refinished again and now it looks like this
I've since replaced those knobs with chickenhead ones.
It dates from Oct '81 and is Ash/Rosewood although Alder and Mahogany are common body woods.
Mine weighs just over 9lbs but G&L's can be quite heavy.
Completely passive but with bass and treble cut controls, the wiring on mine was a mess and I had to get the diagram off the net and sort it out. The three way switch is parallel, single coil and series with bass boost for the single MFD humbucker.
I can get some pleasing vintage P type tones as long as I don't run the controls fully open, but it has a variety of other tones too.
It originally cost me £325 but there's one on e-bay at £799.
Great bass.
