If you discount the various reissues, its been a long time since weve had a proper new model from Marshall to look at. However, Marshall never does things by halves and weve recently been blessed with not one but two new designs. Following on from the exciting KT66-powered Vintage Modern series, its time to check out Marshalls all-new flagship the JVM 100-watt head. The JVMs cabinet and styling are what weve come to expect from Marshall the word iconic is over-used these days, but nobody would argue that it shouldnt apply here. Heavy-duty hardware combined with black vinyl, gold control panel and the famous white script logo produces a reassuring presence that will make any guitarist feel right at home. The JVMs deep steel box chassis is home to a lot of electronics, and as youd expect from an amp with 28 knobs on its control panel, these are all mounted on printed circuit boards.
