Wah Thing Support Notes

Support notes for using the S-Gear WahThing pedal, in both the Standalone App and in a DAW.

Recording a WahThing performance in manual mode using an expression pedal requires some special consideration. Please read the section Recording with the WahThing Pedal.


  1. From the S-Gear Application main menu, open File->Audio Driver Configuration on Windows,
    or S-Gear Preferences on a mac.
  2. Click the MIDI tab
  3. Enable the MIDI input device that you wish to use, by clicking on the enable/disable (on/off) status

When S-Gear receives a MIDI message, you should see the Green MIDI RX LED flash on the MIDI button:


  1. Open the S-Gear MIDI Controller panel by clicking on the MIDI button in the top control bar
  2. Select a Controller slot, S-Gear has 50 controller slots that can be configured
  3. Click 'Learn' to enable learn mode
  4. Adjust the WahThing manual knob
  5. Move your expression pedal to pick up the MIDI CC number
  6. Click 'Learn' to disable learn mode
  7. Make sure that the Controller is enabled by clicking the ON state

To Enable a MIDI input device:

In Reaper Preferences->MIDI Devices, enable the MIDI Device for 'Control Input'.  In the MIDI Devices preferences view, find the MIDI input device that you wish to enable, click and select 'Enable input for control messages'.


To map an expression pedal to Wah Thing:

  1. On the S-Gear track, click the 'Track Envelopes' button 
  2. Find 'Pedal Wah Manual' in the list, click the LEARN button
  3. Move your expression pedal to capture the incoming MIDI CC number, click OK on the dialog box.  The pedal should now be mapped to S-Gear Wah Thing.

1. Check that the required MIDI input device is enabled in Logic Preferences

Use Track Start Controls to Map an expression pedal to Wah Thing

2. Click on the Smart Controls button, click the 'i' button 

3. Map the Wah Thing Manual Parameter to a control

4. Click 'Learn' for External Assignment, then move the expression pedal to capture the MIDI CC message

Add a MIDI Remote Controller in Cubase:

1. Open the MIDI Remote tab
2. Open MIDI Remote Manager to add a Controller (or from the main menu Studio->MIDI Remote Controller)
3. Click 'Add Surface', enter values for vendor and model, then select the associated MIDI input ports

Map the expression pedal to Wah Thing:

4. In the Control surface add a knob, or move your expression pedal to add one automatically
5. Click 'Go to Mapping Assistant'
6. Move the Wah Thing 'Manual' knob and the Mapping Assistant will learn the parameter mapping
7. Click 'Apply Mapping'

Recording a performance with the WahThing pedal in manual mode requires special consideration.

The normal recording process is to record the raw signal on a track, with the effects processing committed only at the final mix/rendering stage. With a manual Wah Pedal, we need to capture the complete performance including the Wah Pedal movement. There are two approaches:

  1. Record the track output including the plug-in processing (recommended)
  2. Record the track input and capture parameter automation for wah pedal movement

We have created the following support notes explaining how to record the track output for some of the most popular DAW software:

Record a live track with plug-in processing - Reaper
Record a live track with plug-in processing - Logic
Record a live track with plug-in processing - Cubase

When using parameter automation to capture the Wah pedal movement, use S-Gear v3.21 or later. With Apple Logic and sample accurate automation, it may be necessary to disable the 'Convolver Buffer Optimisation' option in the S-Gear CONFIG screen.



To configure a Reaper track to record the track output:

  1. Add S-Gear as an insert effect on the track


  2. Right-click on track output 
    Select 'Record: output > Record: output (stereo)'


  3. Record enable the track and go! Once you've finished recording, disable S-Gear on the track, so that you don't get double processing on playback.

1. Create an audio track for the guitar input. Insert S-Gear as an effect, set up your sound and map an expression pedal to Wah Thing. You will monitor the guitar on this track, so enable the 'I' input monitor button.

2. Set the track Output to 'Bus 1'

3. Create another audio track for recording. Set the input to 'Bus 1'. Arm for recording.

The processed Wah performance will be recorded on track 2.

1. Create an input audio track (1) for your guitar, add S-Gear to the track, set up your sound and map an expression pedal to Wah Thing. Enable input monitoring to get live audio into this track.

2. Create an Effect track (call it Wah Bus), set the output to 'No Bus', we don't need to hear this bus, it's just for routing.

3. On track one, add a send to 'Wah Bus'. Make the send a 'Pre-Fader' send (useful later for monitoring options).

3. Create another audio track, call it 'Wah Guitar', this track will be used to record the wah-processed guitar. Set the track input to Wah Bus, leave to output mapped to the Stereo Bus for monitoring. Record Enable this track.

That's it, you can now record processed guitar to track 2.

Note: Whilst recording you can monitor the guitar on either track one or track two (the record track). You might prefer to monitor on the record track, since this is also your playback track. To monitor on the record track, set the input track fader to zero and enable input monitor on the record track. Avoid monitoring on both, else your headphone levels will be too high.
