SN20H – JCM900 20-Watt Head

The compact JCM900, the Marshall SN20H captures the essence of the early-’90s high-gain era in a smaller, more manageable format. With 20 watts of valve power, it delivers that tight, punchy, aggressive JCM900 voicing but at volumes suited to home studios, rehearsal rooms and smaller stages.

Despite its size, the SN20H has the familiar character of the bigger 4100/4500 heads — fast attack, crisp upper mids and a focused gain structure that works brilliantly for classic rock, punk and early metal tones. The low wattage also means you can push the power section harder for richer saturation without needing stadium-level volume.

This example is Brand New(B Stock), supplied in original box(opened & re-taped) with foot pedal, power cable & instructions.
