My first bass was a home made PBass thing that was so bad it defied description.
This was replaced by a white L Series PBass ( sold $180.00 in about 1969 )
PBass replaced by Fender VI Series 2 in 1969 ( sold for $300.00 in 1976 )
1959 Telecaster Deluxe(sold for $360.00 in 1976)
In today's market there's over $50K in that little lot and that's without a 72 Tele custom deluxe and Gibson Les Paul SG Custom ( sold for $60.00 only made for 12 months ) so now we're up in $100K territory all up.
