This has been asked to death a million times I am sure but I just wanted to check if there is a way to do this all digital now.
Id like to use SPDIF and have left as dry and right as amp. I don't use stereo delays or reverb when recording because I can do that in my DAW after the fact with better sounding reverbs and delays. Plus its more versatile to mix those things in the daw. So I only need mono. This leaves the other side of SPDIF as a spot I'd love to grab the dry signal in case I want to re-amp later (I usually do).
