The Black Panel Fender Vibrolux Reverb is one of the more desirable amps of the era. Fender discontinued the Brownface Vibrolux Amp in early '64, almost immediately replacing it with the Vibrolux Reverb. Sporting 35 watts of power from two 6L6 tubes in a 2x10" configuration, these amps broke up fairly early compared to the bigger 6L6 Fenders of the era thanks to their smaller speakers, output transformers, and power transformers. The result is a dreamy-sounding drive that would require blistering volumes or modification to get the same tone out of the bigger Super Reverb or Twin Reverb. As well, you'll notice the "BRIGHT" switches per channel, which do exactly what they say they'll do and create even more tonal possibilities for this killer stage amp.
