Is there a buffer that will work before a fuzz?
« on: February 19, 2010, 10:23:24 PM »

My dilemma is this: I would like to use a noise suppressor to cut down on hum from both my amp's FX loop and my Strat's single coils.
However, as many of us know, fuzz pedals don't react to buffers well. So my Boss NS-2 effect on the input impedance makes the fuzz all sputtery and ugly.

However, I also love fuzz pedals! Is there a buffer I can stick between my NS-2 and my fuzz pedals, to make the fuzz pedal think it's seeing the pickups?

What about a Foxrox buffer? Would that work?

I have a fuzzface which sounds bad not just after but before a buffered pedal. It sounds good on it's own but it sounds sh*t (more treble and high-end clip/fizz) before my two buffered pedals. (one digitech, one behringer) The perceived volume is about the same as bypassed but i have a feeling that my FF boosts some frrequencies so much that the buffers start to clip.
I have a feeling that my buffers could be bad. Altough they work with ODs and other stuff.

Yeah the foxrox is the best i have tried !

The fuzz is the problem, not the buffer.  You can mod the fuzz into modern life with a pickup simulator, like at AMZ (muzique.com), or more simply, a series resistor between the switch and the fuzz circuit.  The latter 1 cent part may be what makes the Foxrox the best anyone's heard.

Look at the buffer part of the link.  You can adjust the cap and series resistor to the FF type part of the circuit for the RC high pass and series resistance you want.

Pickup simulator?
I looked around, is this it?

Hmm....You might have to be a little more straight forward, I'm not sure I follow.



My goal here is to simply be able to use my fuzz pedals with my NS-2 on, so they can be less noisy, without altering their tone.

This in between your gate and your fuzz. I've never tried but many here seem to like it:

Ohh...okay. never struck me to look in the lab notebook.  icon_biggrin

If anyone has tried it, it would be awesome to let me know how you like it. Cheesy

This worked well for me before a couple vintage low impedance fuzzes.
Thanks for the help a while back Gus!!

^im trying to wrap my head around that schem, so the second part looks like a darlingtone pair, yes? That's the fuzz face?

The first section would be used as a buffer? Does it change the tone at all?

Gus tells you what to use in the schematic.
Just use everything up to and including the 10K resistor.
Chose a cap value. .1uf should be fine for most everything.
Adjust the 10k higher if you need a higher impedance.

Everything after the first stage is a tweaked fuzz face.

Make a box with an input and output jack.  Put a 10k resistor between the jacks.  Use this box between the noise suppressor and the fuzz.

John Lyons: Okay, that's what I understood, too. Just wanted to confirm, thanks.

Does it affect the tone at all?

earthtonesaudio: Yeah, some people were saying that, but does that change the tone?

I really want to retain my tone. Smiley

The fuzz circuit I linked has a low pass filter (high cut) at the output and a simple 10K series input to the FF type section. 


azrael what fuzz circuit are you using, is it a FF type or an opamp type or a BMP etc ?

Awesome. Do you or anyone else know what I could potentially substitute for the MPSA18? I don't have any on hand. 2N5088, maybe?

I wonder if its possible to make a pup-sim using a gyrator?

A high gain 2n5088 or 89 will be fine as a sub for the MPSA18

The gyrator thing came up in another thread

Quote from: bool on January 24, 2010, 09:36:08 AM
Has anybody ever used a gyrator to buffer a fuzz? Perhaps this would be the most
configurable, smallest and cheapest way to get near the kOhms and henries of a typical pickup configuration(s).

Bad, bad hiss in most cases. Semiconductor gyrators have noise issues that real inductors don't in most cases.

The resonant peak followed by a steep rolloff is not all that different from what you'd get with a mis-tuned second order lowpass.  Just make the feedback cap a little too big.

mostly FF type, also Tonebenders.
