HX Stomp 4CM Plus external pedal in loop

[MRGuy]

Has anybody tried running the HX Stomp in 4CM while also running an external pedal in the loop as well?  As I understand it, the Stomp's loop is dual mono or one stereo loop.  What I'd like to do is use one side for 4CM and the other side to use an external delay pedal I have.  I've been trying to do it but not having much luck.  At first there were noise issues but I took care of that with an iso xfmr.  For whatever reason it doesn't seem to be working.

You need to use two FX Loop Blocks - FX Loop L and FX Loop R. That leaves only 4 blocks for everything else. Also, in Global Settings>Ins/Outs, Return Type has to be set to "RETURN".

Hi thanks for the reply. Yes I used both FX Loop Blocks, one L and one R, and the Return type is set to RETURN.  Still messing around with it but so far no luck.

What are your connections like? You have a TRS to dual TS cable connected to Stomp’s Send?

 

When you say it’s not working, what’s happening?

Yes I'm using a stereo Y cable coming from the stomp's send.  The signal flow within the Stomp is Red Comp - FX Loop L - US Double Norm preamp - FX Loop R.  When I engage FX Loop R it seems to cut the Send From FX Loop L.  Meaning the signal is going straight to the Amp's loop and bypassing the preamp, so if I engage FX Loop R, my amp won't change channels nor do the EQ controls work.  I have the FX Loop L set off when the US Double Norm preamp is engaged, and vice versa when it's on.  Even if FX Loop L is on, engaging FX Loop R still seems to cut the send from FX Loop L.  Hope this makes sense

If you want to use the amp's preamp without the US Double Norm and the amp is in Loop L, then set the USDM  and loop L to one footswitch, saved with one ON and the other OFF. That will toggle the signal through the amp with the Loop ON and through the USDM with the Loop OFF, bypassing the amp. The signal will always go through the Loop R. With Loop R ON you'll get the external delay, OFF bypasses Loop R (no delay). If your 4cm is wired right:

 

L/Mono send to amp input, amp send to L Return, L/Mono Output to Amp Return, R send to delay, delay to R Return, It should all work.

Are you bypassing the FX Loop R block with a footswitch, via snapshot or just manually? Are you sure the FX Loop L block is being bypassed at the same time?

[MRGuy]

Here is the signal path.  Guitar is going to Stomp L input.  From the Stomp L main output to the effects return of a Bogner Helios.  From the effects send of the Helios to the Stomp's L return.  I'm using a Stereo Y cable from the Stomp's Send with the left side going to the Helios input, and the right side going to the input of a Strymon Volante.  The output of the Volante is going to the right return of the Stomp.

 

RD2RK - Yes I have both the FX Loop L block and the USDN block on the same footswitch (if the USDM is on then the FX Loop L is off and vice versa)

 

phil_m - I would like to leave FX Loop R on all the time and just the Volante footswitch to toggle on and off

[rd2rk]

Also, if you're going to toggle the delay from the delay footswitch, save yourself a block and an AD/DA conversion by putting the delay between the L/Mono Out and the Bogner Return.

[MRGuy]

rd2rk - Forgive my ignorance but I'm not sure I understand what I'm doing different to how you describe the wiring.

 

The reason I want the volante "inside" the Stomp is to be able to use a reverb block after it which I wouldn't be able to do if I put it between the Stomp and Helios return. 

[rd2rk]

Sorry, it sounds like you're already doing what I said. It should be working. Switching channels on the Bogner will only have an effect if the Loop is ON.

That’s fine, although, you are going through a round of unnecessary A/D-D/A conversion that way. But I’m just about what happens when you engage the FX Loop R block. Are you sure the FX Loop L is toggling off?

With FX Loop L is not toggling off when I engage FX Loop R, but the send going to the Helios input seems to be cut, meaning everything is going only the effects return of the Helios when I turn on FX Loop R.

Attach a copy of the preset so we can look at it  Something's not right, and if the wiring is correct, it has to be in the preset.

[MRGuy]

Here's the preset

The only way I can duplicate your problem is to set the RETURN TYPE to AUX. When set to RETURN, it works as expected. Double check that setting.

[MRGuy]

It is set on Return and I just tried toggling it back and forth, but still having the same problem.  I'll keep plugging away at it.  Thank you for your help

[rd2rk]

Make sure that the TIP lead from the HXS Send is in the L Return, not the R Return. Next thing to do would be to check all of your patch cables.
