I have just built this, and it works great with my Boss Tremolo, but when I use it with a fuzz, it doesn't work as it should.
The blend knob functions like a volume knob.

Is this because of some weird interaction between the buffer and the fuzz circuit, or am I doing something wrong?
Thanks!
Whoops, I just realised that I posted this in the wrong area! Sorry!
