Marshall 2555X Silver Jubilee Reissue Valve Head

Full Description

Based on JCM800 2203 and 2204 Master Volume models, the Jubilee amplifiers were the first Marshall products with Pentode/Triode switching, which halves power output.

The Jubilee Series featured an innovative, if somewhat unusual, preamp circuit which had three gain 'modes'; Clean, Rhythm Clip, and footswitchable Lead Channel. The Bass, Middle, Treble and Presence controls, although shared between channels, were re-designed and offered more tonal variation than any other Marshall Product had before.

There have been some feature improvements made to the 2555X. On the back panel the original 2555 had two speaker output jacks and a rather awkward Output Impedance Selector. For easier operation this selector has been removed and is replaced by fiver speaker output jacks ranging 16 Ohm to 4 Ohm. The Mains Voltage Selector from the back panel has been removed, as each 2555X amplifier is now fixed to match the mains voltage of each country.

There are also some minor cosmetic improvements, the handle end caps are silver metal instead of black, the input jack nut is chrome instead of black plastic, and the Mains/Standby switches look slightly different.
