Hi, I am paying attention to mono and stereo routing, which includes paying attention to which models are stereo and which models are mono, along with settings (such as the effects loop).
The way I am using the effects loop, it is invariably "send mono" and "return stereo". I have purchased the requisite cables for proper breakout. That said, the first question:
1. Can I or how do I "send mono" when the effects loop is set to stereo? The way I am doing it is to use a mono cable for "send mono" and, of course, I am using a "stereo breakout / break-in cable" for "return stereo". In general, I am placing the effects loop behind a mono signal path (not always, see next question).
2. I was surprised to find that the wah and volume models are stereo, yet they are placed -- by default -- up front in the block/signal chain. That phenomenon is, in most cases, negated by a mono sum as going into an amp/cab/ir chain (be it a built in model, or by way of effects loop via x-cable method). I guess that the stereo/mono routing is not entirely applicable to, say, the HX where multiple-signal paths can be configured, but applicable to things like the pod go (not a complaint, per se).
Number 2 above is not a question, per se, but an observation. However, there is a question here:
What if I have wah/volume routed out the effects loop, in which I have a mono cable for "send" ? Does that mean that the effects loop send is the "left channel" (or right channel, or pick one... sort of -- that's question number 1 above).
While here, since instrument-in is mono, it would make more sense -- that is, if you plan on running a full stereo chain to the outputs -- to put the "stereo volume" model block behind the stereo-wah model block (if the volume pedal is directly following instrument-in, it is invariably mono, depending on the model characteristics and settings, of course -- such as "pan" or field-width).
The first question (question 1) is probably the most important question for me. Thank you.
