bazz fuss fun

[Yun]

i was never a fan of this ultra simple circuit- until last night 

it's quite fun to fittle with, i was bread-boarding this circuit, and here's my personal findings suitable to my taste:

C1= 20uf (no joke)
Q1= MPSA18
R1= 100K
D1= 1n914
C2= .01uf

Additions:

-diode clipping circuit
-Tone control

Sounds like:

This is where the 30 minuits of breadboarding FINALLY paid off    :  This IS one of my faveorite fuzzes right now.  It sounds VERY buzzy and synth-ish while still retaining a lot of touch synsativity. 

Other sounds you can get is that VERY sout after buzzy Led Zeppelin tone, poppy synth tones, etc.  sounds very much like effector 13, or Z-vex, suprisingly. 

So what's the point of this thread?  i havn't a clue

I did a Layout for this circuit because of a post on here for someone looking for the Beatles "Revolution" sound and this build was suggested by someone.
I really like the BazzFuss and I truly am not a Fuzzy person    but this circuit is Very Cool indeed!

Nice.  20uf doesnt surprise me much.... on mine I had an input cap tone control that at the bassiest at around 10uf and I still wanted more!  I settled with a 1N4001 diode from collector to base IIRC thats how its positioned.  I tried a bunch of different diode configurations, and back to back diode configurations.  To be honest, Aside from using a string of back to back 1N914 diode combinations, I noticed only slight differences in the diode arrangments I tried.  Most of the differences I noticed was in changes in volume.  I liked the added volume of using an LED, but it didnt fuzz up as well as a silicon diode did.  I think a good compromise would be two Bazz Fuss stages in a row (similar to the buzz box on home-wrecker.com) but use LEDs for clipping diodes in both stages.  I'd like to try that someday.  I also used a darlington transistor.

The version I made has mods from Tim Escobedo incorporated into it.
Sounds fantastic, have a look;



There's also a perf build as well!

thats the layout where there's three 1N914's pointing one way, and one 1N914 pointing the other right?  I liked that diode combination also.  Really though, aside from using the LED or a germanium diode, I hardly noticed a difference in tone using any variation of a silicon diode aside from a difference in output volume.  I'm guessing the LED is louder because it clips at 1.4V instead or .7V.  And germanium is practically useless on its own in this circuit clipping around .3-.35V for a 1N34A

Hey, mr.Mark; do you have a schematic for that revolutionized bazz fuss eh?  I MUST do this build!!!!!!!!!!!!!!!!!!!! 

For the tone control- i just used mr.Andy's (dragonfly) Fat conrtol. 

What's with the 1Meg resistor going to ground eh?  Pulldown resistor?

Here's the schem Yun;

I love the bazz fuss and have built several to some degree modified circuits. One of them turned out to be a fairy nice bass (guitar) fuzz. Still the standard (version 3, iirc) bazz fuss is a great explosive and thick fuzz. I've found it works extremely well with a "flat-mids" BMP tone controll.

[Yun]

yeah, i just realized that it was the Tim one, mr.Mark    your layout through me off, you little stinker 

Other than breadboarding- this is the first time i actually boxed up a bazz-fuss.  I used to just build the buzz box with an lpb-2 in front, and a BMP tone control with a recovery stage.
