This is called GES Noseburner :twisted: . Is posted in the Experiences page in my site.

don't have a good decay (the same problem that happened with the Muff Fuzz, anyone knows how I correct this?

From looking at the schem Munky the second stage doesn't have any bias on the base of the transistor which would mean that only during part of the signal swing is the stage biased correctly, and it is the signal itself which is biasing the stage. Simply put, the second stage isn't biased at all.

To fix this I would put a cap before or after the diode to keep DC from the collector away from the base, and attach a 100k -  220k resistor to the wiper of a 10k trimpot with the other end going to the base, this will allow you to properly dial in the bias on the base of the transistor.

Hope this helps,

Jay

Thanks, Jay. I played a little more with the circuit, and put only the Bazz Fuss part to remind of the sound, and I found that the Bazz Fuss was causing this problem. I removed the comment in the page. I tried the stages in parallel too, but don't sound good.

It looks very similar to the Whisker Biscuit at RunoffGroove.com, minus the Tone control and output stage.

It should work as drawn, though, since the Bazz Fuss doesn't require traditional biasing.

Now I saw the WB schematic, and looks very similar. But the WB have more gain than my circuit (I think), because he uses a darlington transistor and two Big Muff Stages. The version that I put in my site is the first, I'm planning more things to put in this effect. Maybe in the next week I can put something new.

I posted a untested schematic of the final version of the Noseburner. Take a look.
