In celebration of their 50th anniversary, Marshall have introduced a new line of 1-watt amplifiers that model popular amps from each of Marshall’s 5 decades. The JTM1 is based on the popular bluesbreaker amps of the 60s. The JPM1 is based on the plexi amps from the late 60s and 70s. The JCM1 is based on the popular JCM 800 amps from the 80s. The DSL1 is based on the JCM 2000 models from the 90s. The JVM1 is based on the JVM series from the 2000s. The amps come in head or combo models.
