Set the Q between 0.5 and 0.707 to recreate those classic sounds or experiment with the Q for different amounts of overshoot.

Tilt EQ is a slope filter that allows broad adjustment of the tone using just two parameters: Frequency and Gain. The Gain parameter sets the maximum gain of the filter relative to the center frequency. For example, a gain of 10 dB would set the maximum gain to 10 dB. The gain at the center frequency would be 0 dB and the minimum gain would be -10 dB, therefore a total of 20 dB of EQ would be applied. | Tilt EQ is a slope filter that allows broad adjustment of the tone using just two parameters: Frequency and Gain.

Filter applications
The Filter effect is a very versatile effect. Possible applications:
- one-band equalizer
- boost the input of an amp block
- boost the signal level for leads
- high-pass or low-pass filter
- envelope filter
Here's an example, emulating the Eric Clapton / Fender Mid-Boost: "Use the Filter block. Since the max boost is 25 dB set the filter order to 4th which will give you a maximum of 24 dB. Set the type to Peaking. Set freq to 500 Hz. Vary gain and Q to taste." source
EQ types
Variable-Q Filter
The Filter block provides Variable-Q EQ. Many “classic” graphic equalizers use variable-Q designs which may be more familiar to some users as opposed to constant-Q filters. In the Filter block this type is selected by choosing the “Peaking2” type.
Analog Shelving EQ
The Filter block provides “Lowshelf 2” and “Highshelf 2” EQ types. These types recreate the analog shelving filters found on classic mixing consoles. These filters are somewhat quirky and exhibit “overshoot” which gives them a certain musical quality. Set the Q between 0.5 and 0.707 to recreate those classic sounds or experiment with the Q for different amounts of overshoot. These filter types are great for getting that massive sound associated with passive equalization.
Tilt EQ
Tilt EQ is a slope filter that allows broad adjustment of the tone using just two parameters: Frequency and Gain. The Gain parameter sets the maximum gain of the filter relative to the center frequency. For example, a gain of 10 dB would set the maximum gain to 10 dB. The gain at the center frequency would be 0 dB and the minimum gain would be -10 dB, therefore a total of 20 dB of EQ would be applied.
Notch
Fractal Audio:
"Gain doesn't apply to a notch filter. Only frequency and Q are relevant." source
Create an Envelope Filter
There's no dedicated Envelope Filter (Auto Wah) effect block. You can achieve this effect by attaching an Envelope to a Filter (or Wah) block.
You'll find examples in this thread, this thread and on Axe-Change. Or try the Psychadelic Duck preset (Axe-Fx II).
