Uberschall tone test

I think low-end's too out of control and high-end's a bit too buzzy, so it kinda makes the tone sound too scooped.
 
Thanks for comments.

It is easy to get out of control low end with this amp.
Also I find that the treble needs to be set quite high otherwise the tone disappears.

I haven't got the balance right yet so I will keep experimenting.
