Maybe I got the answer to get rid of it! Not sure what's the cause, however. I unplugged the outs from the stomp (I was with the headphones) and the feedback was gone, then I went to plug the left output to the return plug of the interface and it came up again. I moved a couple of cables and even in my home PA no feedback whatsoever. I'm emailing diretcly Vertex Effect to understand better what's happening here. Thank you very much for your answers guys!

I'll try that, or I can l just unplug the output to see if this makes a difference, since I was playing with the headphones. I can tell you that I had the same problem by going to a mixer with both outputs. Thank you very much.

Thank you very much for the answer. Yes I tried with every value of the input impedance parameter on the stomp and nothing changed. I usually set it to 1 MOhm. The fact is that the buffer interface should have the send input/output passive (not buffered) and the squeal is still there. I can't wrap my head around this. I need to check cable by cable I guess. Maybe there is a problem with the power supply(?) (also this is a guess).

Hello guys, I have a hybrid setup with an HX Stomp acting as the core of it. The signal flows in this way: GTR ->Pedal Pawn Fuzz -> Crybaby->Vertex Effects Buffer Interface-> Hx stomp Input I have some ODs in the LEFT effect loop Right effect loop is used when I want to use a real amp with 4CM Left output goes to Amp return when using 4CM, L/R outputs go to FOH otherwise. I built the pedalboard to have the maximum flexibility in terms of routing. Now, when using the Stomp with amp sims I noticed a high pitched feedback/squeal (like a microphonic pickup type of squeal), the only fact is that I was playing with headphones so any microphonic pickup issue should be off the table, I also tried to switch guitars and to my surprise nothing changed. I went through the troubleshooting and I plugged the guitar directly intop the Stomp and I could go with the highest of the gains without problems, I also plugged into the PP Fuzz and the Wah bypassing the buffer interface and I came to the conclusion that the "problem" is the buffer interface. Do you have any explanation for that? That interface cost me a lot and I would not like to sell it or to put it off the board. Thank you in advance for the answers.

Hi gents! I just finished wiring up my pedalboard and I can't solve this issue. My signal path goes like this I go with a 4 cable method: Guitar -> Hx Stomp Input -> Splitter cable -> [R side goes to AMP From AMP SEND -> Return R] [L side goes to switcher -> Return L] -> from HX OUTPUT -> Return AMP. Now my problem is when both loops are engaged and some outboard pedals are on I get a high pitch noise like a feedback. I cannot get where is the problem. Can you help me?
