There’s a guitar piece I’m trying to make work, but first I simply *had* to reconfigure effect chain, making the POD a module in the effect loop of the GSP21. It means I can couple the amp simulation of the POD with the superior reverb models of the GSP which took a couple of hours. Prior to this, I had to decide whether to use the GSP or the POD, and switch the plugs around.

In the process, I discovered that the “effect loop” parameter of the GSP actually has two additional values I didn’t know about: “Stereo Summed” and “Inline Summed”. The GSP is an ancient piece of hardware, I’ve had it for years, but I never knew about these options. As it turns out, this anecdote is kind of silly because it turns out that they weren’t useful for what I wanted to achieve anyway.
