No sound when using FX loop?

[zodymarc]

I'm sure I'm doing something wrong.  I have a Catalyst 60.  Everything works great with the standard footswitch.  When I try to add my looper pedal, I run a cable from Send on the back of the Catalyst to the input on the looper, and another cable from the output on the looper to the Receive on the back of the catalyst.  When I activate my looper, I can hear my previously recorded loop in the speaker but there is no longer any sound from the guitar itself.  What am I doing wrong?

Is the Loop activated in the Cat's Settings? You need the app to check this.

Does the Looper need to be recording to hear it's input?

Yes, I checked and the FX loop is set to On.  After your post, I turned on the loop and tried to play along and that didn't change anything.  Not even any hum from any of the amp selections.

That’s the key question and I don’t think it’s been answered. Seems that when the looper is playing back the recorded loop it is no longer passing through the input it is receiving from the guitar. Your guitar signal is being blocked by the looper.

Ok.  I think what you are saying is that the looper will need to be in the chain between the guitar and the guitar input jack on the Catalyst?  The looper I'm using is the Ditto from TC Electronics.  I was hoping to use it in the FX loop so that I could use one guitar tone with the looper and then a different tone with the guitar live.  I'm a little new to this so sorry for what are probably dumb questions.

Oh....and I should have noted since this was probably very confusing:  The loop that I was hearing from the looper through the Catalyst was a loop created on my old amp that I sold to buy the Catalyst.  It was still recorded and waiting on my looper when I plugged it in to the Catalyst.  Now that I have erased that loop, I can't record to the looper (with it plugged into the FX jacks) and can't hear my guitar through the Catalyst when the looper is plugged into the FX jacks.

You can use it in the Catalyst FX Loop. Your cabling should be:

Guitar -> Catalyst Guitar Input -> Catalyst Send -> Looper Input -> Looper Output -> Catalyst Return (Receive?).

 

As noted earlier the FX Loop block in your Catalyst preset needs to be activated. If activated it seems that your guitar signal is either not being sent from the Catalyst Send (a cabling or Catalyst issue) or is not being properly received by your Looper (a Looper or its settings issue). Since you were able to hear the originally recorded loop that means the signal is being sent from the looper outputs and received properly at the Catalyst Return.
 

Check your guitar and all your cables. If your Looper has a headphones output check that to see if the signal is being received in the Looper.

I don't have a Ditto, but I set up a Looper preset on my HXS and wired it this way - works perfectly.

Well, I don't think there's any getting around it.  Something's wrong with my Catalyst.  I plugged the looper into the guitar input loop (Guitar>Ditto>Catalyst) and it worked fine.  Plugged the looper back into the FX loop (even reversing the cables just in case)  ((Send>Looper input, Return>Looper output, Guitar>Guitar input)) and I get no sound whatsoever from the guitar.  Looper seems to still be working as I do hear a click when I double tap to erase the loop.

 

Then I pulled the cable between Send/Looper Input, still nothing from the guitar so plugged it back in.  Then I pulled cable between the Return/Looper Output and the guitar is back (but of course, no looper).  All cables are 1/4 Mono TS.

Just to be sure - the Cat's LOOP is enabled, the switch is on FX Loop.

To test your FX Loop, patch the send to the receive,

If there's no sound there's a problem.

Thanks for the suggestion.  I put the cable with one end in send and one end in receive, then strummed the guitar.  No sound.

Time to contact support!

Try to call them if you can, always works better for me than a support ticket.

The physical switch beside the return input is on "fx loop", not "power amp" right?

[zodymarc]

Well, turns out there really was a glitch.  Walked through various troubleshooting steps with a Line 6 rep and it definitely has a problem.  Sweetwater is swapping it out for me.  Had a real good experience with both Line 6 and Sweetwater though.  You guys were also a big help.  Thanks everyone.

 

As a side note.  I really like the amp.
