I'd like to add a pot to the NFB loop, so I can dial it in and out... this way, I could eliminate the hiss and get more clean headroom generally, but could wind it away and thus get the overdrive back when I needed it... which would suit playing in different bands.
Does anyone know the best way to go about this? Also, what kind of pot should I use? Where shall I locate it? Just tell me everything in as much detail as possible, please. :)
