I've owned 2 classic shapes ( part T-Bird ish some call them )
First one i bought in the early 2000's , single Armstrong pickup, about 1984 ish and passive ( first classics used Bill Lawrence pups ) and paid approx £350-£400 , exact price eludes me cos it was nigh on 20 years ago. Dear cliff the prices have changed !!
Also, up to early this year, i owned classic deluxe ii , so it had a fancy Silky Oak top, pair of Armstrong pickups active. £1800. !!! Now sold
The circuit on these have a dual filter for each pickup.
