FX Loop In Fryette Power Station PS-100 No Longer Working

Hi, after having the FX Loop in the PS-100 work for years, it suddenly is no longer working.

No matter which pedal I put in it the FX Loop, it no longer affects the sound. For the last 3 years or so I have been using a Source Audio EQ2 Pedal in the effects loop of my Fryette PS-100 and it had worked flawlessly. NOTHING has changed in my set up.

All of the sudden, there is no effect when the pedal is engaged or dials turned, including if I bump up the output level. I then take the same pedal with the same cables and put it in the FX loop of my EVH 5150 and it works perfectly. As such, it isn’t the cables or the EQ2 pedal.

I also tried my boss GE-7 EQ pedal in the PS-100 FS Loop and it doesn’t work, yet it works in the FX loop of my EVH. Same with a distortion pedal.

Even though the cables are not the problem, given the pedals work in the EVH FX loop, I even tried new cables and no luck with the PS-100.

I have the FX level in the PS-100 set to low (which is recommended for pedals), however, switching it to high doesn’t do anything either.

I don’t have a foot switch for the PS-100, nor have I ever used one with the unit.

What am I missing and/or what could go wrong with the Effects loop that it stops working?

Thanks!!!

Hi Kenton and welcome to the forum!

Thanks for listing all the sensible things you tried; that’s really helpful.

It’s a series FX loop so if something were wrong, you would typically get no sound.

What happens if you connect a cable directly from the FX send to the FX return?

Is your PS-100 definitely entering operate mode? Or could it be in bypass?

Hi Dan, thanks for the quick feedback!

I connected a small patch cable from the FX send to the FX return and there was no change. I got full sound.

And yes, it is in operate mode, otherwise I would not be sitting here typing this as my head would be blown off with 100W of love turned to 7 out of 10. Uploaded a picture showing the same.

And if you plug in FX send and do not plug in FX return? What happens? This should break the signal path. Maybe the switching jack is faulty and is always connected to the FX return?

I’m going to private message you to get some more info.
