I built this with no substitutions and get a bit of randomness, but nowhere near that exhibited in the video. Moreover there's some extraordinary hissing noise, which may be a build problem. I'll give it a second look tomorrow, but thought I'd share my preliminary findings in case anyone else had this issue too.
I'm hoping to get to it in a couple weeks. Did you socket the transistors? HFE might make a difference. I'm also not sure if using a 2n2222 vs the PN2222 might impact the circuit.
I didn't socket them but I can certainly pull them out and add sockets. I may do just that too. I used MPS2222 by the way which I believe should be the same as pn2222 but I can double check the datasheets.
I put in two 2n3616 in place of the 3904s and the hiss is gone. It sounds even better with a boost in front of it. I love pedals like this. The weirder the better.
Ahaha, STRANGE FUZZ FRIDAY!
ReplyDeleteThanks!
ReplyDeleteCan we get a higher res pic tho?
fixed

DeleteI am always very grateful for your work.
ReplyDeleteMay I request a layou?
I would like to request the layout of marshall gv-2.
Best regards,
I’m making a lot of pedals using your layout.
ReplyDeleteThank you very much.
I still can’t master eagle cad.
Excuse me,can I request a layout?
It’s two circuits from Jack orman(AMZ).
•Shaka 5 overdrive
•Multi fuzz(mini muff)
I will create it with point wiring,so please create a layout if possible.
With respect from Japan,Please take care of yourself.

ReplyDeletecan i ask you to build a BOSS harmonist ps-6 layouts? looks like it's very good
ReplyDeleteMark this one verified. I used the suggested Q2-Q4, and an S9018 [hFE 97] for Q1. Sounds just like the demo.
ReplyDeleteI did modify the layout slightly by reversing the potentiometer so the board sits on its bottom for stability.

Yup. Worked as the video with no substitutions.
ReplyDeleteConfirmed working from the etch.
ReplyDeleteI used:
Q1: 2N4401
Q2: 2N222A
Q3: 2N4401
Q4: 2N4401
Sounds just like the sample - like an 80's arcade!
HI there, is possibile to add some potentiometers to control some parameters for more felxibility?

ReplyDeleteI’m a little confused by the out… it doesn’t seem to connect with any of the components on the board… am I missing something?
