Problem with pedal and sound output: POD X3 Live

Recommended Posts

I bought a used POD X3 Live some time ago, but was never able to get any sound out of it. The outputs seemed completely dead—no hum, hiss, or anything. 

 

I just now reinstalled the latest firmware (not an update, just a reinstall) and I can finally get sound, but it still behaves very strangely. When I switch to patch A, B, C or D, the LED next to the pedal indicates Volume mode, but no sound comes out in any pedal position. If I manually click the pedal into Wah mode, sound comes out, but the pedal doesn't affect either the Wah or the Volume! 

 

I found some online discussion of problems with the pedal, but nothing definitive. 

 

Anybody know about this?

Well you can open it up and check the cable running to the EXP pedal but if that is fine it may be a component that need servicing.

Thanks. I went through the pedal calibration procedure and it appears the pedal is non-functional. It acts like it always reports being in the heel position. This would explain why no sound comes out in Volume pedal mode, but does come out in Wah mode, and why pedal position has no effect on the Wah sound. 

 

Any tips on servicing the pedal components? I've got test equipment and solder!

Fullcompass.com has many replacement parts, so I would check there.

 

Still check the physical cable inside the unit.

Just removed the bottom cover. No obvious problem with the pedal PCB (or anything else). Re-seated the ribbon cable from the pedal assembly to the main board, doesn't seem to have helped. The pedal status LEDs work but the pedal position sensor seems stuck in the "heel" position. The sensor is some kind of non-contact setup, maybe a Hall effect sensor?

Interesting: Fullcompass.com has this "Foam tube for Line 6 POD X3 Live guitar multi effects pedal". I don't remember seeing anything like this when I was just inside the unit. Is it possible that this tube surrounds the pedal position sensor and is necessary for it to work, and mine is simply missing? (I bought the unit used.)

I bought the foam tube from Full Compass and installed it. No change. For some reason the unit thinks that the foot pedal is always in the heel position. I just saw another unit on eBay being sold for parts. It seems to have the same problem with the foot pedal. Maybe a weak spot in the design?
