RJS Amplification 76/100 Master Model 100 2018 Black

Sorry, this listing is no longer available.


The RJS 76/100 is one of the more uniquely voiced amplifiers in our series.  These amps are based on the 2203 series introduced by a well known UK amp maker in 1976. Pre phase inverter master 2 input.  This amp is not a clone of a 2203 but modified to have more saturated gain than a stock 2203 Marshall plus the pre phase master works much better especially at bedroom levels. 

You can get great plexi tones and 80's type tones out of this amplifier, and it cleans up really well just by adjusting the volume on your guitar.
