Digitech Whammy pedal 4th gen, I was using it and the sound started to cut in and out. I took it apart to see if there was anything burned out and once it was back together and the power supply is put in the lights blink once and the unit does not stay on. Any suggestions? Thanks!

HEY THERE! I have had similar problems with digitech pedals before. Follow these steps and if the problem is fixable you should be able to identify and correct it.
First identify where the actual problem is. These steps are basically just a "process of elimination" troubleshooting method. This method works for almost any problem with electronics.


1.Plug cable direct to amp from guitar. Have sound? If so its not cable repeat this step with the other cable. Good?

2.If both cable are working plug direct to pedal and use headphones to see if you hear anything. If there is sound it is the output jack.

3.If you still don't hear anything turn on the metranome or "rhythm button and crank the volume ALL the way UP. If you faintly hear a click then it is definitely a power supply issue. Be sure that the AC adapter you are using is 9V and at LEAST 1300mA. I know from experience if the milliAmps are lower than that it will work but not draw enough power to output any sound.
(If you have an old Nintendo system that power supply will work)

4.If a new power supply is used and all other options don't work the pedal is probably broke....I would try a factory reset just to be sure it is not a setting you bumped or something.
HOPE THIS HELPS! Good Luck!

Make sure you have the OFFICIAL Digitech power adapter. Universal adapters or those for MOST other pedals will NOT work... things may light up but you will NOT get audio. This unit requires an adapter supplying 9 VAC (not DC) at about 1 amp. These AC output adapters are not very common and people get the units without an adapter and try using universal adapters and they do not work. An AC adapter is used by Digitech so they can generate both plus and minus voltages internally. I don't know what your utility power voltage is in Cebu, so you need to get an adapter for your voltage that will give 9 VAC output and fit the power jack on the unit.

Likely the input rectifier and filter in the SR16 has shorted diodes or caps. Should be easy fix for a competent electronics tech.

It's probably one of the plugs on the effect pedal. Is it loose? Open it up and look at the wires hooked up to the terminals

It sounds like the guitar level input to the unit is too low.

NOTE: With this product you MUST use an amplified or electric guitar that has a preamp within it.

If you have a straight guitar that does not have an amp in it, buy a preamp to first run the guitar through.

A friend of mine had the exact same problem. In his case the pedal is only good for hammering nails now. If it still has it warranty I'd say look into that, if not you've got nothing to lose. Open it up, look for unattached wires. Also, try using a battery instead of an AC adapter..

Hi,

I know you hate this answer, but it needs to be repaired. It has a circuit board inside, and there's really not a work-around. But it is broken. I totally understand about not wanting to send your gear out, especially if it's a pedal board you have set just right, and are completely usweed to using. You'll be a lot happier with it if you get it fixed though. Or find another one on eBay. I sold all me Digitech pedals when I got my Pod - but that's just me, I use a lot of distortions and it fit the bill better for me. I used Digitech pedals for about 20 years and thought I would hate anything else.

Take care.

Try contacting their service center rep at (801)566-8800. They might send you a schematic for the pedal if you explain your situation. They do recommend using the original power supply PS0912 which should still be available. Hope this helps.

Personally, I like to have all "tone effects", such as wahs, distortions and equalizers in front of "time effects" such as phasers, chorus, flangers and delays. See my set up in the photo. Guitar input is from right to left, starting with the wah pedal.
