I might jump in a bit late.
The audio file definetely sounds a bit weird. But it does not give any deeper hints what went wrong.
You only played single notes, while chords or power chords would give a much deeper insight into the sound of the distortion.
We didn't have the chance to hear your guitar without distortion, by just rolling down the amp gain a bit.
Well the next time I have tone issues (which I hope there isnt and past experience suggests there wont be) I will remember your advice. Thanks CK
