I still think that this 'issue' is being overthunk; start off with a decent audio interface, of the 'Focusrite' type (I use Tascam gear; there are many others, at all price points...), and use any guitar pedal on the input to get tones, if you don't want to use Vst's. It's about as simple as it gets, and gives guaranteed Good Results, every time, with no fuss. Monitoring can come from the headphone o/p of the interface, so you can hear what's going on before recording anything. I can see no downside to this; it ticks all the boxes, as far as I can see. You're always going to need such an interface anyway, for recording into a PC. What's wrong with doing things this way..?
