Marshall ST20C Studio JTM 1x12 Combo

The Marshall Studio JTM ST20C is a 20-watt, 1x12 tube combo amplifier that replicates the iconic tone of the original 1960s Marshall JTM45 in a compact, hand-built package. Itfeatures a power reduction switch allowing players to drop output from 20W to 5W for lower-volume playing, making it suitable for home, studio, and small club use. 

Key specifications and features include:

• Tubes: Uses dual 5881 power tubes and three ECC83 preamp tubes (two preamp, one phase splitter) to capture the original JTM's creamy highs and loose lows. 

• Speaker: Equipped with a Celestion G12M-65 Creamback 12-inch speaker, offering enhanced power handling and bass response compared to vintage originals. 

• Controls & Connectivity: Features two bridgeable channels (High Treble and Normal/Loudness), a series FX loop, and a speaker-emulated DI output for direct recording or PA use. 

• Construction: Built in the UK factory with a finger-jointed plywood enclosure, gold piping, and a metal "coffin" logo, weighing 17.8 kg (39.2 lbs).

• User Feedback: Reviews generally praise its versatile, warm tone and build quality.
