PRESENCE: These are controls that work in the power section to reduce attack and brightness. They work on a different frequency
than the TREBLE Control, and depending on the mode chosen, and the amount of Gain dialed up, can sound higher or lower than the
Treble frequency.
In the Rhythm mode it dials in sparkle and shimmer, letting clean sounds cut through better. Balance
the Treble and PRESENCE until the desired blend is reached. In distortion or high gain sounds in the
ORANGE Channels’ Variable High Gain Mode, you will find it very helpful in darkening and compress-
ing the sound for single note work. Set the PRESENCE low and this compression will also focus the
notes and omit any unwanted “buzzy” frequencies. For high gain chording try higher settings of the
PRESENCE Control to bring out the harmonic haze. In the RED Channel the PRESENCE circuitry is
quite advanced because it switches from one type of PRESENCE located in one part of the power section, to a different PRESENCE
circuit located earlier in the pre-amp section. This switching makes the complete transformation possible that delivers the BLUES
mode authentically and the MODERN HIGH GAIN absolutely over the top! In the BLUES mode the PRESENCE is similar in strength
and frequency to that of the ORANGE Channels’ Clean mode. Set low it warms up single notes ‘til they purr. At high settings it adds
bounce and improved dynamics that can really dynamics that can really help when you want to back your guitar volume down and
“clean up” for rhythm playing.
When the MODERN HIGH GAIN mode is called up, the PRESENCE makes the move to a new place in the circuit and gets revoiced
to work on a lower frequency. Just right for adding attack and urgency, this PRESENCE is the aggression control. It is normal for high
settings of this control to make MODERN RED seem extremely loud in comparison to the other modes. This is a result of “unclamping”
what worked as the PRESENCE in the other three modes and letting the T-VERB ponies run free. It is in fact, the loudest setting on
the amplifier. Use this PRESENCE with discretion as it can make for some ear damaging, almost harsh sounds if set too high. Try the
MODERN HIGH GAIN mode with the GAIN Control set high, around to . Dip the MID Control to - then increase the
PRESENCEe to dial in the right attack and blend of aggression. You may want to play with the balance between the MID and
PRESENCE Controls as they are somewhat similar in that they are very powerful and dominant in MODERN RED. With these two
controls dialed right, MODERN RED is to this day the most huge and heinous crunch we’ve come across. When you hear this, you
will probably won’t believe that this could be the same amp that moments ago was crying the blues with such mournful conviction.
Another cool use for this alternate PRESENCE frequency shows up when you use the VINTAGE ORANGE Channels’ Clean Mode.
Using this example: Use the Channel Cloning (TM) switch on therear panel and
revoicethe ORANGE Channel to MODERN. You will hear your rhythm sound get louder and much punchier. This difference is largely
due to the moving and revoicing of the PRESENCE. This occurs automatically when you “Modernize” the ORANGE Channel and
now you instantly have a Vintage clean pre-amp with a Modern power section. This can be useful at larger gigs to boost the clean
sound volume level or simply as an alternate voicing of the same mode style.
REVERB: These self explanatory controls deliver the rich all tube reverb sound. Although the circuit is the same for both ORANGE
and RED Channels, the amount of REVERB available is not. In the RED Channel there is slightly less REVERB available overall
because of this channel’s very nature. The reason behind this is two fold: (1) that it is easier to prevent the massive amount of Gain
and signal strength present in the MODERN HIGH GAIN mode from causing unwanted REVERB oscillations.
(2) This channels aggressive nature lends itself more to musical styles where high settings of REVERB are
simply not traditional. Don’t worry...there is still plenty of REVERB for drenched solo work in the BLUES mode.
Simply run the control a little higher than that of the ORANGE Channel.
