X FUZZ

[deadastronaut]

ahhhh thats you...i wondered who that was on my youtube ..hi darksid

cool, sounds quite chunky ,

i was twiddling with my mixer settings and the Xrock and found it can get in the realms of heavy chunky riff stuff with the right eq...

my mixer has a nice mid section, 2 controls, mid and sweep...i'd like to nail that as an eq in a pedal for sure...

but for now i think i'll keep the xrock as is...i'm pretty happy with it. it must be, its been on the bread for months now...

Deadastronaut Hi, Yes I have just added a TON there prvda differently http://vk.com/vas67?z=photo176059711_326061425%2Fphotos176059711

Alright Rob I replaced the 1uf Between the stages and put in the 470nf and I get synthy notes again when I dial the bias back. Hey! Cool.  Ok I'm still not completely satisfied with it but it's getting better.  Seems like there is less separation between the clipping types now.  Maybe I'm just fuzz blind after a/b testing for an hour.  I'm calling it quits for now and will fiddle more with fresh ears later.  If you get a chance try that second output stage I posted and see what you think.  It's is not the same and has its own character. Your mileage may vary

Would someone look this layout over and see if I made any mistakes?  Nevermind the component numbers vs the schematic. Just the values.
The gain is bottom left, tone is bottom right, the volume is top right, and the bias is the two pads just left of Q3

[deadastronaut]

no 470k R6.

[haveyouseenhim]

no 470k R6.

Awesome. Is that all?  I was able to add a semi standing resistor to the layout. I can't update the post at the moment but I got it in there.

[deadastronaut]

yep looks ok apart from that..

you might want to use  250k pot for bias.. thats what i have on the vid. (my mistake.  )

[Darksid]

haveiouseenhim and what happened transistor D3,?

[WhiskeyMadeMeDoIt]

Transistors are marked as Q and diodes are marked as D.  This is the new schematic it only has 2 diodes not 3 like the original.

[deadastronaut]

yep, 3 leds were there just to  lift it, before i addded the recovery stage...

[deadastronaut]

@mike: where is Q2's 10k?...R5..

[haveyouseenhim]

@mike: where is Q2's 10k?...R5..

R4 on my layout.

[deadastronaut]

ahh gotcha....need more coffee. 

[Darksid]

Mike I have my layout I have done differently.

спасибо она хорошо выглядит!

Do you have one with just the transfer?

[WhiskeyMadeMeDoIt]

Darksid that looks nice. Good job.  Post one without the components.

Hey guys
I'm using 2n3904 transistors in xfuzz, but I can't obtain that cool synthy sound. Is it possible that it's transistors fault or I took wrong schem?
Took the blue one from page 6.

WHen I first breadboarded I tried 2n5089s instead of 5088s and it was really fuzzy so transistors might matter a bit. HfE values and all that jazz

[Darksid]

Instead try 2n5088 transistors KT3102Em with them works well too Tolko need them to turn 180 degrees to the other-pinout. http://my.mail.ru/inbox/20vasiliy/photo/_myphoto/151.html

[Mario44]

What should be minimum hfe for this circuit?
The easiest transistors to get for me would be BC.
