I just got this a few days ago so I haven't had a whole lot of time to mess around with it. I can get it to record and then loop back around and play it over and over and then solo or whatever over it. My question is can you record a clean riff and play a distorted riff over it or vice versa? I have a TSL602 and I recorded a clean riff and tried to play a distorted riff over it but as soon as I hit the lead switch it started playing the clean riff I recorded as distorted. Is it possible to do what I want, or do I just have to live with all clean or all distorted?
