Introduction

Use this guide for realigning the envelope modulator on a Dunlop Crybaby Pedal.

The envelope modulator is what modulates the amplitudes inside the pedal. Without it, the pedal will not create or amplify sounds like it is supposed to.

If a Dunlop Crybaby Pedal is dropped or damaged, the envelope modulator could fall out of place. This can result in the pedal not working properly, and not producing the sound. In order to fix the pedal, the envelope modulator will need to be realigned.

If the pedal is unresponsive or suddenly stops working, this easy fix could bring your pedal back to life. This guide will walk through the process of taking off the back panel, finding the envelope modulator, and tightening it back into place so it is realigned.

Tools

Step 1

Remove all four of the 5 mm screws from the bottom panel of the pedal using a Phillips #1 screwdriver.

Step 2

Twist away the bottom panel to expose the inner components.
Do not remove the bottom panel entirely.
Be sure not to pull too hard on the wires when twisting the bottom panel.

Step 3

Locate and pick up the envelope modulator.
It will have a cylindrical gear attached to it.

Step 4

Move the nut and washer to the upper section of the thread.

Step 5

Place the base of the modulator between the two rods of metal that will hold it in place and align the straight spur gear with the cylindrical gear.
You will see the teeth of the gears interlocked.

Step 6

Use a 1/2" wrench or metal pliers to tighten in the nut and the washer to hold the modulator in place.
You can test to see if it is tight enough by rocking the pedal back and forth as if you were playing, and seeing the cylindrical gear rotate.
