X FUZZ

[bluesdevil]

I'm pretty sure I got the transistors in correctly, but I'll double check.

[WhiskeyMadeMeDoIt]

Bluesdevil if you want to reduce some of the circuitry I would just make the xfuzz clipper section and skip the dual clipper setup. It doesn't add much but it does make the circuit lots more complicated. Be sure to try the dual output though it gives you a lot of sonic possibility.

[bluesdevil]

Thanks Whiskey, I haven't tried the dual output stages yet..... will give it a whirl.
Just noticed you have the 3rd stage biased differently than the original I'm working from. Do I need to change it to work with new 4th stage?

Heres my X-Fire 1590A build. This one has both fuzz stages, the X-rock side is modified to use 2 pink LEDs with 470K resistor and 470nF cap, wired similar to the x-Fuzz clipper. The input caps are the same, both clipper sections use the same 1 uF coupling cap after Q1. EF Q3 isolates the tone circuit, instead of the presence pot a fixed 51K is connected to ground, the rest of the tone circuit is the same- it works very well. Only the first output stage is used- not enough room to put in both in this box- although I might try again with ⅛ Watt resistors.. It sounds great, a superb design.

i ended up tinkering with Gus's ASDF  a bit, and went for a more heavy type groove .......

cleans up nice too

i used a pregain as i just prefer the control of that...

cheers for the inspiration gus....lots of tweaking fun to be had.

well worth breadboarding..if only to annoy your neighbours.  

edit:

vero layout...something for the weekend..



oops left off the 100uf cap...like i say breadboard it first...

Hey DA,

I just put together your x-fuzz using the layout at http://tagboardeffects.blogspot.com.au/2014/05/x-fuzz-by-deadastronaut.html and I bloody love it...so much fuzzy goodness...sounds great with my Rick copy...just gotta box it up now.

Thanks for your great work and keep it....

...and, by the way, I used BC549s and they work great!

cool...

i still haven't boxed mine yet....been busy..

a friend sent me this link...

at least he put my name/s on the box..

        Cost 399.00 meaningless squiggles - what's that in English ?

        Cost 399.00 meaningless squiggles - what's that in English ?

I think that's only about $63 US. A bit insulting for a DeadAstronaut design in my opinion!

[duck_arse]

that's 3.30$ per page. what's the going rate?

[deadastronaut]

$3.30 a page aint too bad for me really.....

Nice one whiskey, hows the noise/hiss?

I wanted to follow up. On hunch and following the most logical idea that made the most sense, I assumed the hiss must be a product of the breadboarding etc. So... I did a quick 20x12 vero layout yesterday and formally soldered it up. Hiss gone and this thing sounds absolutely fabulous.  She's going in a 1590B in the next few hours!



There may be a tiny mod there or so such as a 2n3904 for Q1 but otherwise it should be pretty much the exact same circuit. I'm going to make here a 4 knobber.

And another big thank you. This is strictly for my pedal board (hope it was ok to munge the name a little - was supposed to read space rock xfuzz but its a box in a day so...) and your moniker is on the bottom plate with full credit. I hope to go back and get it on the front but was in a hurry today because it's going with me to rehearsal in a couple hours. Anyway, thought I'd post the semi-final right as I was testing it:

Good job!

I would like build this effect, but the vero layouts I found is the 2 knobs version.
Can you share with us your vero layout?
I need the 4 knobs version (Pre-Gain, Volume, Tone, Bias).

Thanks!

Is anyone here?
Can I introduce a standard big muff tone stack between last two stages without modifying any other components? Will it work properly? I'm not very good with schematics.
And what can be done with this "white noise" thing? The schematic is kinda "bigmuffy", and in big muff there's a little of that kind of noise, but somehow in this fuzz it's more apparent despite having less gain stages. Tried a 220pF (and even 470pF) cap on clipping diodes, it helped, but not a lot.

This should be the easiest try..

Although that BMΠ tonestack needs a 13dB gain "recovery" which I'm not sure if can be obtained by Q2 clipping amp...

[Elijah-Baley]

Here's my corrected layout:

I'm gonna use the Jdansti's layout . Waiting for Tayda's pack.
First time for me with this kind of board, I usually use stripboard.

[kzl666]

For the last two stages I meant between Q2 and Q3. As I can see Q3 is basically the same recovery stage which can be found in big muff right after the tone stack. I've tried it already and something went wrong, it doesn't sound right (like in my big muff). Also, now that I have introduced that recovery stage (before there wasn't, just a plain simple schematic from the first page of this thread) "white noise" thing is just crazy and the sound is kinda gated. I've used KT3102E as Q3, maybe that's why. I need to rebuild it properly and use something like 2n5088 (somehow it's hard to find any decent transistors here, can't even buy something like BC546/547C).

 Built one with the tagboardeffects.blogspot.com vero layout. Sounds killer. I used a 57nf input cap.

Thank you.
