Thanks !!!

I will definitely check those out. I was thinking of getting a breadboard on my next tayda order. Pedalpcb also sells a add-on pcb to help breadboard too.

Wouldn't you want to breadboard this idea out before ordering a PCB?

i would but i don't know how T_T

i just made a schematic for a modified woolly mammoth board i wanna make.
basically i just took a mastotron schem and replaced the volume pot by the boost section of the fuzzolo.
My question is would this schematic work ?, and should i keep the volume pot of the mastotron.
i plan to use 2n3904 and the component values of the woolly mammoth.
i wanna check with people here before i order this from oshpark.
i am a noob at this so any feedback would be great ! Thanks !

Hi m-kresol !!
Thanks for the pointers! i will try the improvements on the power section.
Funny you should be the one answering me :p i just finished one of your hydrogen fuzz oshpark project last night !!!
As for this schem i used the feta complis one on oshpark just because its the one i used for my big cheese clone and i like it a lot !

As for the transistor switching, a lot of other projects i have looked at usually use a dpdt for one transistor, they keep the signal part running into the base of both transistor but have the collector and emitter switch on the selected transistor. Since the signal is going into the base i just tough why not keep C and E connected and just change the signal path to the transistor i wanna use. The thing is i don't know what effect having the C and E connected all the time :/.

i have made a schematic! but i wanna run pass here just to be sure that it would work before i oshpark it.
would the switch for changing Q2 work ? or do i have to use a dpdt one ?
Also if it does work can i use a dpdt switch and use the other side of the switch to change Q1 if i wire it the same way ?
my guess is no but you never know until you ask !!

Thanks !

i use these for smd.

its easy to solder in. just use some blue tack on one side and stick it in the rigth position, solder one side , remove blue tack and solder the other side !

Nice build !!! Those pesky on on on switches are what are keeping me from building one T_T

Absolutely love the idea ^^  all the musicians I know and I have crossed , when I tell them about the hobby I get the same state of amazement O_O... They all just don't know about it. I tell then all you need is a soldering iron, a pcb with a good build doc ie: a madbeans project, and tayda as a good starting sourcing site for regular components and your good to go.

If it gets someone else into the hobby I am all for it!

Holycrap ! It's way better than I expected !!! Will this be the end of me going to the print shop to make stickers oO and the end of dropy lacker oO!!!

Very nice !

Did you manage to mod it to work with a normal expression pedal or we still need to build one like the old version ?

Holy moly I thought that it was just in Montreal the toilet paper hysteria xD I am on paternity leave so I have been so much disconnected from the current events xD

Ahhh oki cool thanks BuGG! So the op amp is just a input buffer and recovery stage. Ok then I will try socketing q1 too and not q3 since it's a clipping transistor. I also did try to have the cheese option grounded via foot switch... It did work but it cut like 15% of the volume :/ don't know what I was expecting xD it does the same when using the selector switch... But I can now use the gate setting with the no tone or regular tone selection... Not the most useful mod but I am having fun tinkering on the circuit maybe I could make a small boost circuit for the gate mode... Anyway thanks for the info again ! I am gonna try and do a board for a stand alone life pedal green ringner and stick it in the pedal ^^ you should maybe think about making a board for it BuGG ^^ it's a lot more useful than the classic tentacle/green ringner !

I made a couple of OSHpark feta complis board and was thinking of doing my own board with some mods.

I did try to swap q2 with a 2n1308 germanium transistor. It really mellowed the volume and distortion, it made it more bassy too. Looking at the schematic I don't understand , is it a op amp fuzz ? To me it looks more like a type of hybrid. Also what are q1 and q3 for ? My guess is q3 is for the tone control. I only got q2 socketed at this time but would love some ideas you guys might have for mods. I can read a schematic ok, but circuit design I am pretty much at novice level! I am trying to do these types of projects to hopefully learn a bit and do something cool I love this fuzz so much and would love any feedback or ideas on what I could do to mod it or any info how it works !

So far I wanna have a switch to change q2, thinking of putting the gate control as a knob. I would also love to had switches to change some components value that might help change the character of the fuzz. Maybe adding the octave part of the retrograde would be cool... As I am writing this I realize that I should really buy and learn how to breadboard xD well anyway hope someone can help me with this! Thanks in advance !!!

Money sent !!!! Gotta stock up on those 50% boards !!! Took a florist and a glitches too been a long time since my last madbeans original project !!! Hyped as ffffffffff !!

XD I am just imagining poor Brian filling up all the future orders of the sales thinking what the f**k did I just do -_-
