The main consideration is making sure the cab is Stereo if using stereo effects before it and desiring a stereo output. *thumbsup*Well, you've got me there. I guess I was thinking of what I think is typically done in the studio, you mic the cab, then apply delay and/or reverb. I know one reason delay and reverb are typically? post-amp, so as to avoid adding distortion to delays and reverb and cluttering the sound, but I guess there's no reason it can't be done post-amp and pre-cab. Thanks.
