One sure way to beat inflation and present devaluation of the bond market to invest for the future is to put your money in vintage electric guitars. Paul McCartney left handed guitars and original flying v guitars will have demand in spite of recessions.
Especially in demand are vintage Gibson hollow-body, Fender's vintage sunburst Stratocaster and vintage Fender guitar amplifiers. Nostalgia for early rock is only one reason for the high valuation of vintage guitars and accompanying guitar equipment. The main reason demand is so high for vintage guitars is the sound they produce is as unique as the instrument itself.
Each guitar was just a little bit different when these vintage guitars were made decades ago and the technology to produce them was in its early stages. Many of the electric pick-ups were hand-wound, or if they were machine-made, just a little different from the next. If the pick-ups had a few less strands of wire, the sound would be just a little different. Sound boxes as part of the bodies were not made exactly uniform either, making the guitars sound just a little different from same product lines making each guitar just a little unique. Finally, the electronics degraded over time causing each instrument to be a little different from the next.
Marshall and Yamaha solid-state amplifiers on the market today are cleaner, unlike original Fender guitar amplifiers which were made with tubes. Fender and Epiphone tubed vintage amplifiers had tonal qualities that are prized because they are not "clean", but sound unique. Guitarists playing vintage guitars and vintage amplifiers can be identified by those with good ears.
The best way to chose a vintage electric guitar and/or vintage guitar amplifier is to play it to hear its unique sound qualities. Hearing the sound a vintage electric guitar produces or the unique sound of a tubed vintage guitar amplifier assures the investor of the musical demand an electric guitar may have. Low Fender serial numbers on the back of the body indicate more of the historical demand a vintage electric guitar may have. If your potential investment has both a low serial number and that unique and "special" sound of a fine musical instrument, you have struck gold!
