The Story

Your hands never leave the strings.

Ever wanted to have real-time control of an effects pedal parameter without having to bend down and change a knob with your hand? The WingMan replaces the factory knob on a pedal you already own, so the parameter moves under your foot while both hands stay on the guitar.

No expression jack. No cable. No power.

The Setup Race

Eight steps. Or three pushes.

Expression Knob vs. Expression Pedal

The stopwatch paces the reading; it is not a timing claim. What is real is the step count — eight versus three, then play.

Summary: setting up a conventional expression pedal typically takes eight steps — buy an expression pedal, find a pedal with an expression jack, run a TRS cable, give up a board slot, enter expression-assign mode, set the heel values, set the toe values, then play. Installing a WingMan, the Expression Knob, takes three steps — remove the factory knob, push on the insert that fits, push the wing knob onto the insert. Then you play, using your foot to move the wings. Three pushes, then play.

An expression pedal, the usual way

8 steps

  1. Buy an expression pedal (typically $39–$199)
  2. Find a pedal that has an expression jack (many pedals have none)
  3. Run a TRS cable between them
  4. Give up a slot on your board for the expression pedal
  5. On many pedals: enter expression-assign mode (often by holding footswitches while powering on)
  6. Rock to heel, set the knob values for the heel position
  7. Rock to toe, set the knob values for the toe position
  8. Then you play

 

WingMan

3 pushes · then play

  1. Remove factory knob from effects pedal either by pulling off firmly or removing set-screw
  2. Choose which insert fits your pedal by pushing it down onto knob shaft until it has a firm grip
  3. Push Wing Knob down onto insert

Use your foot to move the wings left and right to control effects parameters hands-free

 

Three pushes.
Then you play.

Hands-free

What a sweep feels like.

  • Change your delay time during melodies
  • Speed up and slow down your tremolo or phaser with the intensity of your song

Built for the long haul

No Pain for Your Pots.

The WingMan is extremely durable and designed to have the least amount of impact on your pedal. It's engineered with a wide shaft and compact wings to put the least amount of torque on your pedal's pot shaft. Turn it left and right with your foot — don't push down on it — and you eliminate the chance of excessive torque. We have never had a customer report a broken pot shaft with a WingMan.

How it installs

Take the factory knob off. Put this one on.

All eight WingMan colorways in their retail blister packs, laid out in two rows of four on a black grille.

Which insert?

“On the top of each insert is labeled a B or C to depict the two different style pedals they fit, Boutique and Classic.”

“Both the insert and the hole in the bottom of the WingMan are D shaped, so there's only one way they will couple with each other.” The WingMan can easily pull off and onto the insert while the insert stays on your pedal — so the wings come off when you pack the board.

Why one wing is longer

“You noticed that one wing is longer than the other on WingMan, this is to help you with calibration on your pedal. Most knobs have a hashmark on them letting you know when you're at zero to maximum amount of the effect parameter. So use either the long or short wing as your ‘hashmark’ and you'll always know where you are in the effect parameter range.”

Technique

“Use your toes to tap the wings left and right to alter the parameter. Once you have the hang of it you can use the sole of your shoe to lightly grab the pointed wing tips and easily drive the parameter up and down.”
