The timeless tone of vintage handwired, all-valve Marshall
amplifiers have made them highly desirable to collectors
and sonic connoisseurs alike. Due to overwhelming public
demand we are proud to introduce meticulous, handwired
re-issues of three of our most sought-after amplifiers as the
first products in our new Handwired Series – a Series that
celebrates the company’s rich tonal heritage and revisits
the handcrafted traditions and skills that first launched the
Marshall legend.
1959HW Head & 1960AHW/BHW Cabinets
To theminds and ears of many, the mythical100 Watt “Plexi” heads of
the late ’60s are considered the “Holy Grail” of great rock tone. Our
handwired 1959HW transports us back in time to that celebrated era and
the result isa breathtaking re-issue that’sauthentic in every detail – from
those world-famousfront panel legends to the oversized,custom-built,
“dropthrough” mains transformer that lies at the very heart of the beast.
Good looks and impressive specs aside, the 1959HW’s realbeauty lurks
in its unique and highly responsivetone.
To complement the 1959HW’s sonic and visual majesty,we offer the
1960AHW (angled) and 1960BHW (straight) 4x12" cabinets that boast
Basket Weave fret cloth, metal handles, “100” logos and are loaded with
Celestion’shighly-acclaimedG12H-30 (55Hz)re-issue speakers.
2061X Head & 2061CX Cabinet
An authentic, handwired re-issue of the original 20 Watt 2061 head
(1968-1973), this compact, twin-channel, all-valve beauty houses
2 xECC83 valves in its preampand a pair of cathode-biasedEL84s in its
powerstage.The 2061Xfeaturesa solid-state, silicon diode rectifier andis
a very aggressive and surprisingly modern soundingamplifier,while still
possessing that unmistakable and highly desirable,vintage all-valvetone.
Just like the original, the 2061X boasts a point-to-point,handwired,
tagboard circuit, amild-steelchassis and Dagnall transformers.
As theperfectsonic and visual partnerfor the 2061X, we offer the
2061CX – acompact, angled-front 2x12", 60 Watt cabinet loaded with
Celestion’srenowned G12H-30 (75Hz) re-issue speakers.
1974X Combo & 1974CX Extension Cabinet
The 1974X is anauthenticre-issue ofthe fabled 18 Watt 1974 combo of
the late sixties(1966-1968).Justlike theoriginal,it boasts a
point-to-point, handwired, tagboard circuit housed in analuminium
chassis, plus a valve-driven tremolo circuit. At the very heart of its simple,
but effective,two channel design can be found six valves:three ECC83s
in the preamp, an EZ81 rectifierand a pair of cathode-biased EL84s in
the power stage.The output and mains transformers are vital
components in any amplifier becausetheyinfluenceperformance, sound
and feel, so weworked extremely closely with ourassociates at Dagnall
in order to duplicate theoriginal, “off-the-shelf” transformers in all areas.
Another major contributing factor to the distinctive soundof vintage 1974
combos is the way the original 20Watt, ceramicmagnet, Celestion
Greenback T1221 loudspeaker’s tone has softened with age.
In order to recreate the gorgeously smooth tonesof a 35-year-old
vintage Greenback, Celestion not only revisited the 1967 recipe for the
speaker,they alsocameup with a proprietary way of “aging” the
speakers so theysound and feel like the originals made in the late ’60s!
The same exact, exclusive“aged” T1221 Greenback speakeris also
found in the 1974CX,a 1x12" extension cabinet for the 1974X.
