Introduction
The Marshall re-issue range consists of the 100 Watt 1959SLP head, the 50 Watt 1987X head,
the 2245 ‘JTM45’ head and 1962 ‘Bluesbreaker’ combo. All are faithful reproductions of the
originals, which shaped the sound of the electric guitar as we know it.
The main characteristic that these amps share is their simplicity of operation and superb natural
valve tone. Achieving the beautifully organic and vibrant overdrive which is their trademark, can

only be done in one way – crank’em up! The result is pure, majestic tone uncluttered by
unnecessary circuitry. With solos this produces a big, round, warm sustain, full of classic
character. With chord work you get a bark and percussive attack with a natural sounding break up,
which allows each note to ring out in a glorious musical crunch.
FX Loop
Due to high demand, a sonically transparent effects loop has been added to the 1959SLP and
1987X models. This circuitry has been designed to not colour the guitar sound, so that your tone
remains pure. The bypass switch gives you the option of completely removing this circuitry if
desired. The effects loop level selector ensures compatibility with rack processors or floor pedals
(stomp boxes).
