If you discount the various reissues, it’s been a long time since we’ve had a proper new model from Marshall to look at. However, Marshall never does things by halves and we’ve recently been blessed with not one but two new designs. Following on from the exciting KT66-powered Vintage Modern series, it’s time to check out Marshall’s all-new flagship – the JVM 100-watt head. The JVM’s cabinet and styling are what we’ve come to expect from Marshall – the word ‘iconic’ is over-used these days, but nobody would argue that it shouldn’t 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 JVM’s deep steel box chassis is home to a lot of electronics, and as you’d expect from an amp with 28 knobs on its control panel, these are all mounted on printed circuit boards.
