Tone control on bazz fuzz

[Joecool85]

Is there a way to throw in a tone control knob to cut some lows on the bazzfuzz.  I think I could just throw in a pot with a cap bypassing the pot (to let the highs through) and that would work?  Maybe right before the volume pot?  Not sure...Or would it be easier/better to cut the highs via grounding them out on a pot with a cap?

Check out the Deluxe Bass Fuzz on that home-wrecker page. That thickness control is actually a bass cut control. You dont need to build the whole deluxe model though. Just replace the input capacitor with the two capacitors & a potentiometer arrangement.

If you want it on the output side, it might be bit more complex as it relies on the input impedance of the next amplifier stage. On the input side (as on the deluxe version) it has one advantage though... When you cut out some bass it also cuts out some muddyness (with a bass it's usually not a problem but with guitar it might be).

Is there any other problem with having it at the end of the circuit?  Sound wise?

It will sound different. EQ/filtering before distortion sounds different than EQ/filtering after distortion. The difference is difficult to explain.

Try it. if you try similar control after the circuit, the capacitors might need some tweakking. Especially the smaller one might need to be even smaller.

edit:

You can also try other tone controls like Big Muff Pi Style (Check out http://www.muzique.com/lab/tone3.htm ).

Wow, thanks for the site, good info!

Don't thank me. Thank Jack Orman whose site that is.

The article is actually about modifying the BMP-tone control, but the first one is stock. The modified versions are nice too. Surf around the www.muzique.com and you might find some ether good info too.

There are other sites that can help you understand these circuits better. That just came to my mind first.
