52 Marshall Amplification Product Catalogue
For the aspiring bass player we offer our
comprehensive MB Bass Series which offers two
channels throughout the entire range. The Classic
channel presents gain worthy of the greatest rock bass
player and the heavy tone that is expected from a
Marshall amp. The Modern channel hits those super
crystal clean notes when clarity is a must. The higher
wattage amplifiers contain an ECC83 pre-amp valve
on the Classic channel and all amps have a Limiter to
prevent the power amp from clipping. Scoping the
complete bass playing spectrum the MB Bass Series
has an amp to suit the beginner, intermediate or
professional player.
MB15 Combo
At just 15 Watts, the MB15 combo punches well beyond its
expected weight. The 1x8 ” speaker packs the power warranting the
Marshall name, making this a perfect practice amp or smaller stage
amplifier. This compact workhorse has two channels, Modern and
Classic, with a shared 3-band passive tone network, featuring a mid
Voice control. The Modern channel has a switchable compressor
with variable level control.
Features: Two channels, Emulated Line Out, Limiter, CD input and a
Headphones socket.
MB30 Combo
Next in the MB range is the 30 Watt, 1x10 ”combo. The MB30 takes
the budding bass player a step further to hitting the stage with
aggression and growl. Like the 15 Watt combo the MB30 has two
channels (Modern and Classic) with a shared 3-band passive tone
network, featuring a mid Voice control with three modes.
The Modern channel has a switchable compressor with variable
level control. Both channels are selectable via an optional single
footswitch.

Headphones socket and Footswitch socket.
MB60 Combo
The portable MB60 Watt, 1x12 ” combo packs a mighty bottom-end
punch making it ideal for the rehearsal room or the pub gig. Again,
the combo has two channels (Modern and Classic) with separate
EQ for each. The Modern channel features Bass, Treble, parametric
Mid and switchable compressor with variable level control. The
Classic channel with its ECC83 pre-amp valve includes a Boost
switch and has a 3-band passive tone network featuring a mid
Voice control with three modes. Both channels will be selectable via
the supplied single footswitch.

modes (pre and post), External Speaker Output, Limiter, CD input

channels (Modern and Classic) with separate EQ for each. The
