Tuner? / fuzzz? / dirt? / delays? / reverb? / vibe? Etc. Etc. Etc.
Reamping, the process of recording a clean, dry guitar signal and adding in ALL other effects later, isn't the norm in studio recording, and although it's been around throughout the history of recording guitars, it has been used in a minority of recording situations during the era of the distorted electric guitar. It has enjoyed a resurgence in the last 15 or so years due to the convenience of purely digital recording, but capturing the initial signal through at least a distorted amp is still by far the most common method in professional studios. Even in reamping situations, it is almost always the case that a "dummy loop" of effects is used that isn't recorded, but appears in the monitoring signal of the guitarist as he is playing. Pros understand that you don't play the guitar, you play the entire rig, and altering or removing certain elements of that rig from what the guitarist is hearing can alter the way he plays.Great post.
I will say this.. ive always hated the idea that effects/dirt is added later on and not during the performance. For me anyway, I play not only the notes themselves but the SOUND they make as I make them so Im a big fan of how lots of blues and jazz albums have been recorded. Most everything is live with at least 2-3 parts being recorded at one time, and a couple overdrubs ( or everything at once ).. and each artist ( including tone and effects ) being captured directly at the speaker or from the amp, and perhaps mixed with a room sound. This is off topic but your recording comments in regards to the tone engine interested me.
