This brand new UK-built example has been upgraded with Marshall’s sought-after MS-01 modification, providing increased versatility and gain while retaining the aggressive character and dynamic response that made the original 2203 legendary.\u003c\/p\u003e\u003cp\u003eBuilt in Marshall’s Bletchley factory, the 2203 combines the raw authority of a 100-watt EL34 power section with a straightforward single-channel layout. The addition of the MS-01 modification expands the amp’s tonal range, offering enhanced preamp gain and improved flexibility for modern players without sacrificing the punch, clarity and feel that have made the JCM800 a benchmark for over four decades.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\u003cb\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eModel: JCM800 2203 MS-01\u003c\/li\u003e\n\u003cli\u003eOutput: 100 Watts\u003c\/li\u003e\n\u003cli\u003eMade in England\u003c\/li\u003e\n\u003cli\u003e\u003cb\u003e\u003cstrong\u003eMains Voltage selector for Worldwide use.\u003c\/strong\u003e\u003c\/b\u003e\u003c\/li\u003e\n\u003cli\u003eSingle Channel Master Volume Design\u003c\/li\u003e\n\u003cli\u003e4 x EL34 Power Valves\u003c\/li\u003e\n\u003cli\u003e3 x ECC83 \/ 12AX7 Preamp Valves\u003c\/li\u003e\n\u003cli\u003eHigh and Low Sensitivity Inputs\u003c\/li\u003e\n\u003cli\u003eEffects Loop\u003c\/li\u003e\n\u003cli\u003eMultiple Speaker Outputs\u003c\/li\u003e\n\u003cli\u003eSelectable Impedance\u003c\/li\u003e\n\u003cli\u003eMarshall Factory MS-01 Modification\u003c\/li\u003e\n\u003cli\u003eFull Marshall Manufacturer Warranty\u003c\/li\u003e\n\u003cli\u003eCan be supplied with either Black or White Marshall logo.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cb\u003e\u003cstrong\u003eTone\u003c\/strong\u003e\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003eAt its core, the 2203 MS-01 remains everything players love about a JCM800.
