Hey all.

Just slapped together a Bobtavia, you know the one.....DH mods and all. It sounds fantastic, with one exception.
On the lower strings, and in the lower range in general, the fuzz just sucks. I mean, it's terrible. Up higher it sings beautifully, but down low it spits and sputters. Not good.

So, I was wondering...what can I do to get it to clip less in the bass range? Mostly clipping the highs is fine with me, and I can just run something along with it for fuzzing out the lower end.

Thanks in advance, and here's the schem.

you could try to put a resistor to ground in-between the .047 and pin 3 of the 386or just resize the .047 uf cap, the theory would be that youve highpass filtered the input so low frequencies are attenuated. Before you get to that though, I dont think this circuit really 'clips' in the traditional sense. From the looks of it it is a full wave rectifier hence the 'octave' sound. You might be happier doing something like putting a high pass filter at the input but then adding a low pass filtered clean signal to the output. So you have the effect for high frequencies and no effect really on low frequencies.

Anyways if you want to try to adjust the cap, the input impedance is around 50k on the chip so you get a first order hpf with cut off at 1/(2*pi*50k*C). So right now its ~67 Hz which is below the lowest note on a regular guitar. Decrease C to increase the cut off frequency. Try factors of 10 to get in the range you want or to see if it will change the sound as your hoping. (ie 4.7n 470p 47p etc).

Sounds like a plan. I'll report on the results when it's done. Thanks!
