WTF (doombutter with extra mods)

[Cortexturizer]

I love feedback loops, I use one a lot on my true bypass KROK style looper. Damnit, now I gotta build this one to.
Great work!

Thats awesome, thanks for posting. Did you use the standard doombutter pcb or a different one to apply the mods.
I have a functioning doombutter which i am very happy with and reading about your mods makes me want to take it apart and redo it.

standard pcb from Madbean that I etched.  Enjoy, crazy extra fun and flexibility with this one.

Also what enclosure is that, it looks bigger than a 1590b

Its a 125B.  Gives you a little bit more height which was needed.  Hard to get all that "What The" in a 1590B.
Good luck.

Thanks

Can someone explain the wiring of the feedback to me a little clearer, I am good at following directions but I have not yet gathered the comfort thinking conceptually with effects circuits.

Dude, can we get a demo of the WTF'ness?  That would rock.  Great build!

Bigrigg was kind enough to help me with the feedback mod a while back. Here's a crap illustration I made of how to wire it up.

Nice job. Good thing there weren't more mods or you'd have run out of box!

[Guybrush]

Hey Bigrigg

It might be my eyesight but is your regulator transistor facing the opposite direction to what the build doc shows?

I'm having issues with my circuit and I think it's the transistor so was just wondering if turning round might help. A long shot I know.

That's what she said!
I'm sorry, but I couldn't help my self..... I know I know.... Smile!

Thanks for posting up the diagram guybrush

[dulcetpine]

Guybrush, thanks man!

Is the SPST necessary?  Couldn't you just turn it all the way counter clockwise for single repeats?

[Guybrush]

No worries.

I'm really not sure. I remember asking Bigrigg something similar and there was a reason for the switch but can't quite remember what it was. Hopefully he'll show up again on this thread and she'd some light.

I've not actually tried the mod myself yet but the switch is actually a SPDT (not SPST). Should it be on/on or on/off?

[bigrigg]

Hey all, Im alive.  Sorry life has thrown some major curve balls my way.  I will look the posts over and answer asap within the next little while for sure.  Thanks for the interest.

I would love to but....I'm literally starting a new position with work tomorrow, travelling for work etc, selling our current house bla bla.  I can answer any questions, but a demo won't be possible for quite some time.  Sorry.  It hurts me more as I have Pro tools etc and can't get to use it and play with the toys.
