Marshall Studio Classic SC20C 20W 1x10 Combo
Marshall · amplifier
The Marshall Studio Classic SC20C is the 1x10 combo version of the JCM800 2203-based Studio Classic, delivering the crisp overdrive and cutting upper-midrange distortion of that circuit at 20 watts, switchable to 5. The master volume lets the preamp be driven hard at controlled levels, which is the practical advantage the 2203 circuit has over the non-master-volume Plexi in the SV20. The ten-inch speaker gives a tighter, more focused response than the 4x12 cabinets the original JCM800 heads drove. It suits hard rock, classic metal and punk players who want authentic JCM800 tone in a single portable box.
