The JVM Series 100 Watt, valve-driven power stage is built on the classic design responsible for the legendary Marshall roar found in the JCM800 2203 and "Plexi" Super Lead amplifiers - a timeless foundation for countless classic rock and metal guitar tones for over four decades. Featuring a quartet of EL34 valves, this peerless design has been expertly crafted to compliment the extraordinary wealth of tones found in the JVM.
