Weeping Demon pedal broke

Pedal powers up, signal passes, optical sensor lights up but as soon as the pedal moves the power on led goes off, sound cuts out completely, no wah. Also in traditional stomp pedal mode the signal passes but cannot get to switch the the wah mode.

Suspect that the circuit board may have cracked in the vicinity of the power jack. Also check for a switch under the pedal. SOme have them and it might be broken.

The Digitech Trio seems to be frozen, when I start it the red light blinks slow, after pressing the pedal it starts to blink fast but will do nothing after that


This is almost always due to the guitar signal not getting to the TRIO guitar input. The fast blinking LED should go solid red on the first strum. Make sure your guitar volume is turned up and that if you have a volume pedal or tuner or any other effect between the TRIO and the guitar, that it is passing the signal.

Input and/or Output for pedals not passing sound through


I will answer this assuming you have connected the inputs and outputs of both the pedals AND the amplifier/guitar properly. Double-check your connections! ;)

Otherwise...Have you checked all the patch cables to make sure they're ALL working properly? That's usually the culprit in a situation like this, all other things being equal. Cables take the majority of abuse in your signal chain and also happen to be the weak link in the signal chain as well. It only takes one bad patch cable in a series to interrupt the signal.

I would take a pedal with perfectly functioning inputs and outputs and use it to test each cable yer using. If you verify all the cables are in fact working properly (and you are 100% certain everything is connected correctly), that indicates there might be an issue with the pedalboard's onboard electronics. At the most simple, the "From Guitar" or the "To Pedal" or the "To Amplifier Input" jack might be bad. One or more them, in fact, but it only takes one to entirely interrupt that signal chain. The loop section is less straight-forward in that if one of the loops has a bad input or output jack, that shouldn't affect the overall signal chain, nor the inclusion of the other pedals in said signal chain.

So, I think it's one of three things:

1. The pedals, guitar, or amplifier are not properly connected;
2. You have a bad patch cable;
3. Something has gone wrong with the electronics onboard the pedalboard, and this will probably require service.

Hope that helps.

The foot pedal (not the switches) on my "DigiTech RP90 Modeling Guitar Processor does not work...it will move but it changes nothing.


All DigiTech expression pedals use an optical system instead of potentiometers.

Either the light is broke, or the filter.

The filter protrudes from the bottom of the pedal, and is darker at the top and gradually fades to clear at the bottom. If this breaks off, then there's nothing to limit the amount of light to the optical system.

If it is the light, then you'll have to have it serviced by someone qualified to work on it. Your local music shop should be able to help you out.


Hope that helps!

Bypass is fine, LED lights when active, but signal is very low in volume when effect is active. Almost inaudible.


Make sure power voltage is adequate. If using a battery, the LED will light LONG after the batteery is beyond usability.

Problem with the sound? Or is it?


I have this exact pedal. The sound should change as soon as you start pressing it down. With a wah, the frequencies are low at the heel down position and steadily change to a treble higher sound when in the toe-down position. Does the LED on the right side of the pedal come on when you press down? Are you using a fresh battery or a power supply with enough current? Is the "loudness" knob effecting the tone when turned up? If the answer to all of these questions is yes...then I would return it for a new one or send it to Morley for repair. They are nice sounding pedals. The problem could ultimately lie in the optical sensor that controls the wah effect.

Ibanez Weeping Demon WD7 Wah pedal is not working properly


Sounds like a problem with the optical sensor. Your best bet would be to try to get a replacement from Ibanez or take it to a repairman. They are a resistor just like a pot but work by having an LED on one side and an optical "eye" on the other reading the amount of light passed thru transparent film. Morley has replacements for their wahs....not sure if its the same resistance. An audio repairman should hook you up.

The Distortion Pedal has no effect on the sound.


i got d same problm. i fixed it myself.. check all the op amp ic's if they're all gud. if youre not sure, replace all 4 rc4558 ic's. in my case, i still felt a very small output signal from my pedal (equalizers, vol n gain ctrls r gud since they vary when i change the setting) so i suspected that one or 2 of my ic's were damaged. i only replace d last two op amps which my signal passes thru. i also had this problm with my marshall drive master. same diagnosis and solution. check your schematics
