Uh oh. Post number 1000. I think I have a problem. :-p.
Here is a great sounding simple fuzz from a most excellent builder. It is loosely based on Os Mutantes Fuzz, an aggressive, buzzy and squelchy 60s style fuzz. The most noticable addons are the tone control which are big muff based but it seem to have much wider range. There is also an added recovery stage. The original had 2SC1815 (BCE pinout) transistors which easily can be replaced with 2N2222, MPSA06 or 2N3904.
The schematic is avaiable at FSB.
Happy 1000e post ! Cheers
ReplyDelete1,000 is insane!!! I quickly put this together and im not getting any sound. Just went through the schematic and it all looks correct on from schematic to layout to the way my circuit looks. I'm sure it will get figured out soon enough! thanks for posting.
ReplyDeleteCool to giivng it a go!
DeleteI've checked the schematic and compared it to the guts and Os Mutantes schematic and I think I've found a little bug. It is an easy fix though. Remove the 3 row link at column 12 and move the bottom leg of 100nF up one row (row K).
Thanks for taking another look! Just made these adjustments and still no cigar. Could just be on my end now though. Lets see if someone else takes a stab at it! Such a cool sounding Fuzz based on the demos ive heard.
DeleteI built it with the adjustments and yeah nothing coming through mine either
DeleteBummer! We'll see if the tracer at FSB discover more mistakes in his trace. :-/
DeleteOh damn sorry dude!!! I had 2sc1815's in mine and didn't realise the pinout was different, put in 5088's and it squealed like crazy so I swapped em out for 3904's and I think it works as it should (just a little noisy). Pretty sure you can tag it!
DeleteThanks, man! I'll tag it. Does it behaves like the demos?
DeleteIt might be worth trying transistors with less Hfe like 2N2222 or MPSA06 to reduce the noise?
Yeah sounds like the demos, I think the noise might just be from my testing rig, should be fine when I run it through my normal rig. If not I'll try swapping in some other transistors
DeleteCongratulations and many thanks for all 1000 veros :)
ReplyDeleteAmazing!!!
1,000 is a very solid effort Anders. I’m sure the work is appreciated by many builders. :-)
ReplyDeleteThanks Andy!
ReplyDeleteMuch appreciated!:-)
Congrats on 1000!!! Thanks for such a wonderful resource 👍.
ReplyDeleteTop man Anders, many many thanks for everything (and Andy - love your site too!)
ReplyDeleteThe schematic at FSB is now updated and so is the layout.
ReplyDeleteThank you for all tour layouts!
ReplyDeleteGot mine fully working!Sounds like it should.
ReplyDeleteJust threw this together... I used sockets and settled on some bc549 transistors
