Hi Harvey,
ich hab mal eben die entsprechenden Passagen aus dem AX2-Handbuch rausgesucht, vielleicht hilft das ja.
Das sind so die Möglichkeiten:
VOLUME PEDAL
The Volume pedal (Pedal 1 on the Floor Board) acts just like a standard volume pedal. Heel back is volume off, Toe Down is maximum volume. The effect ofhe Volume Pedal on your tone can be profoundly different, depending on where you choose to have it make an appearance in the AX2 Signal Flow.
PRE/DIS/POST
The Volume pedal can be assigned to three different positions in the AX2 Signal Flow:
Pre, Dis, and Post.
If you look at the signal flow chart, you'll notice that Pre places the volume pedal before the distortion box models. In this position, it acts like the volume control on your guitar. Backing off the volume pedal will generally clean up the sound, because the TubeTone model is not being driven as hard. Of course, with some very clean or very driven sounds, the clean up will not be as noticeable. The Dis position places the volume pedal after the Distortion box models, but still before the TubeTone amp model. This is like having a traditional volume pedal in-line with your stomp box distortion. Changes in volume pedal position wont clean up thes ound quite as much as in the Pre position. The Post position will not affect the tone of the channel at all, and should be used at times when you want only the volume and not the character of your sound to change as you use the pedal.
WHEN IS A WAH NOT A WAH?
One of the cooler things you can do with the Floor Board is set up the wah pedal to modulate (which is a fancy but shorter way of saying change in real time) different parameters on the AX2. For example:
Imagine that you have a song where youre using the delay on your preset, set with only one or two repeats, but you want the echo to just keep repeating at the end of the song. Do you have to program a second channel with the Delay Feedback cranked to max? Nope. Just set the Wah Type to 5.11 (to modulate Delay Feedback), set the Delay Feedback control to the minimum amount you want for the main part of the song, then (and heres the key to the whole thing) figure out whats the maximum amount of feedback you want and set the Wah Depth to the difference between the two.
(Math tutorial: minimum feedback = 30, maximum feedback = 85, Wah Depth = 85 30, or 55).
This same idea will apply to using the wah modulation with any of the available parameters:
parameter setting = minimum, Wah depth = maximum minimum.
Being someone with 12EEE feet, Ive occasionally found myself inadvertently working both the wah and volume pedal at the same time. Hey, I thought, why not design some setups where I can make that work for me? Ive used Presence, Speed, and Level settings so far and come up with some cool effects. Use your imagination, and modulate your troubles away.
Mod Assign When is a wah pedal not a wah pedal? Whenever youve chosen Wah Type 5, Mod Assign. This lets you use either an expression pedal connected to the PEDAL 2 jack, or the Floor Board wah pedal, to modulate a selected AX2 setting.
For instance, you could set this up to control your Reverb Decay Time, and then anytime you pressed forward on the Wah Pedal, your Reverb would get HUGE. Back off on the pedal and things are back to normal.
The following settings are available for modulation:
5.0 Preamp Bass same controls as the Main Row
5.1 Preamp Mid same controls as the Main Row
5.2 Preamp Treble same controls as the Main Row
5.3 EQ 80Hz
5.4 EQ 240Hz
5.5 EQ 750Hz
5.6 EQ 2200Hz
5.7 EQ 6600Hz
5.8 Presence
5.9 Tremolo Speed
5.10 Tremolo Depth
5.11 Delay Feedback
5.12 Delay Level
5.13 Chorus Speed
5.14 Chorus Feedback
5.15 Chorus Depth
5.16 Chorus Level
5.17 Reverb Decay
5.18 Reverb Level
5.19 Drive
5.20 Preamp Bass same controls as the Main Row
5.21 Preamp Mid same controls as the Main Row
5.22 Preamp Treble same controls as the Main Row
5.23 Channel Volume
5.24 Delay/Reverb Level
To make things easy, as you spin through the available Mod Assign options, a pair of red indicator lights (one of the Edit Row red arrows, and one of the Control Knobs red lights) will flash to indicate the selected settings location in the Editing Matrix.
When using the Mod Assign feature, youll generally want to turn the setting being modulated to its minimum, or 0 setting. This is because PEDAL 2 will only provide positive modulation it can only add more, and wont take any away. The Wah Depth will determine what the maximum of the modulated setting will be when the pedal is all the way forward (toe down).
Heres an example. Say youve set Wah Type to 5.19 to control your Drive. Set the Wah Depth to 99, and then switch to the MAIN Row, and turn the Drive setting to zero. Now, rocking back and forth on the wah pedal will take you from the minimum to maximum Drive setting.
Now, with the MAIN Row still selected, turn the Drive up a bit like to 30. This sets a new baseline for the modulation remember that the pedal can only add, not take away. So now, the pedal will take you from the knobs setting for Drive up to maximum.
Finally, select the COMP/PEDALS Edit Row again, turn the Wah Depth way down to something like 10. Youll now find that the pedal is modulating the Drive over a pretty narrow range; in our example, youre pedaling Drive from 30 to 40.
Gruß Jochen
