Helpful Hints - Mesa/Boogie Dual Rectifier Road King II Amp Owner's Manual

Helpful Hints:

6.) The GAIN and TREBLE controls are the most powerful controls in all four channels.They should be used with taste and you will
find that many of the best sounds are found with the controls set somewhere in their middle regions. Avoid setting the TREBLE
above 2:00 when the GAIN is maxed as the possibility of unwanted noise and squealing from microphonic tubes increases
dramatically above this setting.
7.) You will notice a substantial volume increase when switching from either the RAW or VINTAGE modes to the MODERN mode in
Channels 3 & 4. When switching modes Always check your MASTER controls to avoid sudden volume increases. It is a good
practice when setting up your channels, to get in the habit of zeroing out the Channel MASTER control each time you switch
modes.
8.) The PRESENCE control determines alot about the voicing of gain sounds. Set lower it will fatten and compress single note
sounds and lend a liquid feeling to the strings in the 3 modes of Channels 3 & 4. Set higher it will add cut and brightness to the
sound and can be useful in keeping Bass response tight, especially at high GAIN settings when searching for crunch rhythm
sounds.
9.) Always keep the dummy shorting jack connected to the "B" SPEAKER OUTPUTS when you are not using two sets of
cabinets for Cab Switching.This will protect the output transformer from damage should signal accidentally be sent to the "A+B"
or "B" OUTPUTS via the SPKR Program switch.
10.) Although Channels 3 & 4 contain duplicate modes, the PRESENCE controls are different and therefor settings and
sounds will not dial up exactly the same. CHANNEL 3 has been optimized for the RAW andVINTAGE modes with a PRES-
ENCE control that peaks just above "very bright" and at the low end of the control gets truly round and squashed.This response
showcases the more warm and fury nature of these two modes. CHANNEL 4 houses a much more powerful PRESENCE
control that has been optimized for the MODERN mode and will go to realms of top end that are frankly ridiculous.
However, up to the 2:00 region its' more unbridled response makes the Recto MODERN mode a force to reckon with. Think of
the difference like this; the entire range of CHANNEL 3's PRESENCE control can be found below 10:00 on Channel 4's
PRESENCE control. It plays out like this; using MODERN IN Channel 3 will require a PRESENCE setting at the top of the range
and conversely, using RAW and VINTAGE in CHANNEL 4 will require a very low PRESENCE setting.
NOTE: CHANNELS 3 & 4: Should you find that you favor RAW and VINTAGE and never need the aggressiveness of MODERN. Or CHANNELS 3 & 4: Should you find that you favor RAW and VINTAGE and never need the aggressiveness of MODERN. Or CHANNELS 3 & 4:
the opposite, you favor the shredding cut of MODERN and have no use for the warmer nature of RAW and VINTAGE, it is possible to
duplicate the PRESENCE controls in CHANNELS 3 & 4 with a simple pot value change. However, before you call and have us send
you the part, we strongly recommend working with the two channels as they are. Much thought was put into how to maximize the
modes for the best performance under a broad range of styles. By spending some time exploring you may find that you come to love,
and actually rely on, sounds you thought you had no use for. Such is the beauty of an amp that is capable of so much diversity.
14. When switching Channels with Reverb applied or switching the Reverb itself in and out of the signal path with the Footcontroller, it
is normal to experience approximately 1-2 seconds of delay before the Reverb effect is mixed back in with the dry signal. See NOTE:
under REVERB in the Rear Panel section of this manual for more info.
Now that we have shared a few hints to make things easier, let's take a look at the controls and modes.
