Done! No issues. It did seem like I had to tweak some levels on my existing patches but that may have been in my head. Either way it's all good. I'm blown away by the Tone Soveriegn (KOT)! Must have spent 3 hours playing with it last night running 4CM into my PRS Sonzera 50 clean channel. All I can say is WOW! What a great sounding versatile "pedal". I've never even heard one much less played a real one so I had no idea what to expect. I see myself working that into my arsenal in a big way. So many possibilites with it and it seems like you'd have to try real hard to dial up a bad tone. 2.81 was well worth the wait! I bareley scratched the surface with the Zendrive (whatever it's called) but for the little bit I messed with it, it sounded great as well.
