1X 12 COMBO AMP / AMP HEAD
Mojotone’s 18watt TMB Amplifier Kit addresses a
common mod made to a classic circuit, but with a few
new avors of our own. The 18watt TMB is based on the
circuit used in vintage Marshall models 1958, 1973, and
1974 (more affectionately known as the ‘18-watters’.)
These original Marshalls were only produced between the years
1965 and 1967, but were highly sought-after for having massive
sounding JTM-45-like tones in a smaller, more manageable
package. Because they were produced in comparatively low
quantities, these amps still remain a ‘lost ark’ today.
18-watters became popular studio amps for many players
and were used, at times, by everyone from Gary Moore, to
The Pretenders, to AC/DC. Over the years, some players have
reported having no use for the amp’s original tremolo channel
and have opted to replace the tremolo controls with a 3-band
EQ, since the original amps were only equipped with a
single tone control for each channel. In the Mojotone version,
we have done just this. We have integrated the entire preamp
section and the tone stack from our British 800 kit (based on
the original Marshall JCM 800 circuit) for a lean and mean,
hot-rodded gain sound. We have also integrated a master
volume control so this monstrous sound can be harnessed
and used in any size room.
Two EL84s give the amp’s normal channel a warm and
round character which, when the volume is pushed higher,
begins to break up into a smooth grind perfect for blues rock
and classic rock rhythm sounds. On the dirty channel, one
can access screaming lead tones perfect for everything from
dim dirty grunge all the way to saturated hair metal sustain!
With our TMB mod in place, this take on a classic beast
now has a normal channel with high sensitivity and low
sensitivity inputs as well as a single volume and single
tone control; the second channel has a single input with
volume, treble, middle, and bass controls. And don’t
forget about the master volume!
