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 […]

Aside from the fact he was a good soul taken too soon, if this rare and genuine tube-amp guru had enjoyed better health and greater longevity, he would most likely have blessed the […]

Gibson GA-80T Vari-Tone

 
GIBSONVARTITONE_HOME_MAIN_THUMB

In the late ’50s and early ’60s, Gibson was apparently convinced the Vari-Tone switch was the way of the future, with its instant access to six different tones. But a high proportion of players who clocked serious miles on their ES-345 and 355 guitars had the switches disabled (and the guitars rewired to mono!). As […]
