It's not all that bad, I did notice today, when I put a fresh battery in it, and fresh strings, that when I clicked it on it killed a little bit of the overtones, still bright as a mofo though, just less, clear. I can't find one of those in America. My neighbor has a OD pedal that is just pure awesomeness for like $200, I'll have to get the name from him next time I see him.
The TS9 serves it's purpose for now. Lol, trying to save up for a MIA Strat, if possible a custom mahogany with flame maple top Strat style guitar, would make this Painkiller sound beautiful
