The Marshall 2525C is the result of downsizing the legendary Silver Jubilee amp into a 20-watt Combo. Answering the prayers of players everywhere!Featuring preamp circuitry taken directly from the original Silver Jubilee diagrams, the Mini Jubilee offers high/low output switching from 20 watts to five watts, while the combo adds a single 12" Celestion G12M-25 Greenback speaker.The mini amps mirror their bigger brothers, with a bass, middle and treble tone stack; presence; output master (footswitch/pull channel); plus lead master and input gain (pull rhythm clip), all via a complement of ECC83 and EL34 valves.
