Rickenbacher Model 200A

 
MODEL200-HOME-MAIN-THUMB

This month, however, we travel way back, to the dawn of the electric guitar itself, to visit an amplifier […]

Fender Harvard

 
FENDERHARVARD_HOME-MAIN-BIG

Given the current craze for semi-small “home” and “recording” amps, Fender’s 5F10 Harvard of 1955-’60 could be the ideal tweed amp, yet, in its day, it fell between two stools and never sold in large numbers. Or, make that three stools. With the Champ and Princeton in its rear-view mirror and the Deluxe and Tremolux […]

Buddy Holly’s ’58 Magnatone 280

1958 Magnatone Custom 280
 
BUDDY-HOLLY-HOME-MAIN-BIG

When guitarists talk tremolo or vibrato, you can bet the magnificent Magnatone amps will find their way into the conversation. The watery, warbling “true vibrato” that the larger Magnatones are capable of producing is never forgotten by players fortunate enough to have experienced it. In searching to expand the Magnatone legend, the subject is likely […]

Excelsior Americana

 
MARTIN0028-HOME-MAIN-THUMB

If you play any breed of twang, country, roots-rock or, well, “Americana,” could there possibly be a better amp than this? Okay, according to specs and tonal preferences, sure there could. But for sheer vintage-hip and all-out cool, you really can’t do better than dragging this 1966 Excelsior Americana to the next Gram Parsons tribute […]
