Helpful Hints:
8.) 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.
9.) When using the Parallel Effects Loop for external processing, the best tonal results are usually obtained with the processors'
Dry/Wet mix set as close to 100% as possible and the Road Kings' LOOP 2 and/or FTSW MIX set closer to the 10% region. This
scheme will retain most of the pure sound of the amp and lower the chance of any degradation due to the processors' limitations.
10.) 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.
11.) When using processing in both Effects Loops, keep in mind that Loop 1 (the Series Loop) comes before the SEND of
Loop 2 (the Parallel Loop). Therefor, it may be wise to configure your processors so that the units used to derive effects such
as Chorus or Delay are inserted into LOOP1 and feed the unit(s) used to produce Reverb in LOOP 2. Generally, Reverb is put
at the end of a string of effects and Chorus and or Delay is put earlier. These are just practices and certainly not rules.
12.) 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.
13.) Although Channels 3 & 4 contain duplicate modes, the PRESENCE controls are different and therefor settings and
sounds will not dial up exactly the same. CHANNEL3 has been optimized for the RAW and VINTAGE modes with a
PRESENCE 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 3s' PRESENCE control can be found below 10:00 on
Channel 4s' 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: CHANNELS3 & 4: Should you find that you favor RAW and VINTAGE and never need the aggressiveness of MODERN. Or
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.
