Just wanted to say how much I'm totally loving the Karl. It's a mean old fuzz but not at all ever at the point of being noise, notes ring through brilliantly. Excellent ring-modish tones, cutting fuzz and still tuneful. Just had a superb half hour just messing about with scales and was having great fun - fun with scales - what's going on??? The voicing on this thing is superb as well - easy to get a good tone, but a little messing with the 'intense' control and you hit the sweet spots and then the smiling starts. Just immense fun with none of the usual fuzz downsides (loss of tone, loss of bass etc).
