Update: I resolved the issue by ordering the stereo breakout Y cable. The hardware I was using was not designed to take 2 mono outputs and create a stereo signal. Thanks for help radatats!

Thanks for the help on this. I think my TRS Y hardware is the issue. I purchased the recommended TRS Y cable from Strymon, and I think this will take care of it.

Yeah, makes sense. This is what baffles me, so the pedal I'm working with is a Strymon El Capistan tape delay pedal, and it has the capability to accepting a mono or TRS input by switching an internal jumper (their website gives instructions how to switch it). I switched it to the TRS setting, and still have the issue, so that's where I'm thinking the effects loop needs 2 continuous LR signals all the way through, or my TRS Y is crap? Strymon actually recommends a TRS Y cable adapter on their website, seen here http://store.strymon.net/1-4-trs-male-to-dual-1-4-ts-female-cable/. But what I'm using is not a cable, instead a smaller solid piece with 2 female jacks to 1 TRS male, all fused in small plastic housing, seen here on this ebay auction http://www.ebay.com/itm/10-each-NEW-1-4-STEREO-MALE-to-2-1-4-STEREO-FEMALE-Y-ADAPTERS-/310674512435?_trksid=p2054897.l4275. Would these perform differently? I'm not an audiophile expert by any means obviously, but trying to learn nevertheless.

Okay, I think there's 1 of 2 things going on. I tested my FX loop with one stereo effects pedal that has LR input and LR output. When I used this pedal, it preserved the stereo effects in the amp head, and did not turn it into mono, which is great, exactly what I want. Then, I tested my other stereo effects pedal that has a TRS input, and LR output, and this is where I'm getting the amp head signal turning mono. From my FX loop send, I'm using a Y adapter to turn the two 1/4" LR to a 1/4" TRS. So I'm guessing that the flextone must have both the 2 individual LR signals intact throughout the entire loop, or I have a faulty TRS Y adapter. Does that make sense? I really appreciate your thoughts radatats for helping me troubleshoot!

My flextone 3 has 2 LR 1/4" outputs for fx send, and likewise 2 LR 1/4" inputs for the return. I'm using two 1/4" out of L & R "send", to a Y that brings it to a 1/4" TRS male into the external stereo pedal input, which I made sure accepts a TRS stereo input. What I have found is that when I run the amp head only, the stereo effects are in stereo, and when I engage the FX loop on my FBV shortboard, it turns the amp signal and its effects to mono, even though I am running two 1/4" from L & R send. I'm assuming the amp is programmed to switch to mono when the FX loop is engaged, I'm just wondering if anyone else has been frustrated by this. Thanks for the thought.

I have a Flextone 3, and when I use the effects loop both the L & R "send" to my external stereo effects pedal, the flextone is sending a mono signal. I want to run the stereo effects (ping pong delay & reverb) in the amp head to my external stereo effects pedals. If anyone has any knowledge about this, I would greatly appreciate your thoughts!
