Mesa Boogie Roadking Head
The Amp is in A+ condition,we just had a complete service done by the Mesa Factory and all new tubes were installed. The Roadking Head includes the original foot switch and foot switch cable. OK so here is a little sale marketing stuff for you!
The multichannel boutique amps and innovative
tone-shaping circuits created by Mesa/Boogie founder Randall
Smith have shaped
expectations of how a guitar amp should perform. But nothing Smith
has done could have prepared me for the new Mesa/Boogie Dual Rectifier
Road King head. Boasting four channels, 12 preamp modes, and controls
that govern each channel's power tubes, rectifier type, loop activation
and cabinet selection, the "NOS-injected "Mesa/Boogie
Road King head effectively gives guitarists a clear path to their
ultimate tone.
Under the Hood
The Road King appears to have a valve for every job:
the head boasts four 6L6, two EL34, two 5U4 and five 12AX7 tubes.
Mesa's
Progressive Linkage power section allows you to use the four 6L6
and two EL34 tubes in five combinations, for power ratings of 50,
100 or 120 watts. Each combination can be used together with any
of the amp's four channels to produce authentic reproductions of
the circuits found in classic amplifiers.
Each of the Road King's four channels has independent
controls for master, presence, bass, mid, treble and gain, all of
which are
arranged in neat rows of chrome knurled knobs. Next to each row
is a three-position mini toggle that allows you to select among
three modes. Channel one offers a choice of clean, fat or tweed
settings; channel two lets you select from among clean, fat and
Brit modes; and channels three and four have options for raw, and
vintage and modern high gain.
The active-channel and effect-loop status are indicated
by bright , multicolor LEDs in the center of the control panel,
and a second
LED display on the panel's left side specifies the active rectifiers
and power tubes. As a final measure of control , the output dial
lets you set the amp's overall level, which can be boosted by
engaging the solo feature via the Kontroller footswitch (included).The
front panel is rounded out with heavy-duty power and standby switches
and a single input.
I t 's on the Road King's awe-inspiring back panel
that the magic begins. Here, a phenomenal 16 knobs, 19 switches
and 21 1/4-inch.
jacks cover every inch of space. Starting from the panel's left
side, there is a slave output with a level control , reverb controls
for each channel and six speaker output jacks that can simultaneously
manage multiple cabinets with different ohm ratings.There is also
a pentode/triode switch, which is effective only on the EL34 tubes.
Next are the channel management controls. Grouped
into individual clusters for each channel they allow you to prese-lect
the number
and type of power tubes, the active speaker banks, tube or solid-state
rectification, the active effect loop ( 1 series or 2 parallel)
and loop 2's mix level . Once you've set up the controls for
each channel, the Road King will activate them whenever you select
a channel with the footswitch or back panel manual channel selection
knob. Unbelievable!
The head's backside also holds the external trigger
inputs, effect loop jacks, loop mix level controls and external
switching jacks
for several features . Of special note is a powerful mini toggle
that activates or bypasses the head's effect loop system. When
by passed, the Road King's front panel output and solo controls
are disengaged and the individual preamp masters become the final
volume controls. I preferred this set up for times when I wanted
the most immediate response and open tone.
Other features on the back panel include the manual
channel-selection knob, the eight-pin jack for the controller and
a switch for spongy
or bold power voltages. The Road King's numerous back panel controls
are augmented on the controller, which has switches for each
channel and loop, as well as for reverb, the solo boost and an
external trigger.
