Feedback Loop diagram

Anyone got one? Just a basic feedback loop pedal.
Thanks.

Feedback Loops are so lame - they actively annoy me just by existing.

Thanks James!

I made one of these, and they're fucking great: the switch means it can go instantly from a very sensible, useful pedal to a batshit crazy useful pedal.

I'm gonna make one of these from the instructions posted but I was just wondering if there would be any problems if I wanted to use a momentary switch instead of a locking one and I mean this in a wiring sense. Would I wire it the same or would I have to do something different?

(I'm still all new to this...)

It would pretty much negate the whole of the bypass loop part of it's job: I used it, in part, to keep noisy pedals out of my chain: you don't want to have to keep your foot on the switch to engage these. Also, while it would be OK for the feedback loop bit, it's more fun to put a big knob on there, and make the loop go berserk with a twist of your toes rather than a simple on/off.

Oh okay. I think I'll just leave it for now. I should probably learn how to make one normally before I go and mess with the design.

Also, I thought huge knob for crazy feedback manipulation was a given with these types of pedals

I was thinking:

Its coming along nicely..

That would be awesome, would look like some crazy laboratory thing, add one of these:

and you'd be in business.

It would look awesome but I think there has already been a thread about how those style switches are fucking useless...

Shhh don't ruin this for me

haha it'd be worth a try I guess, I mean as long as the feedback circuit gets bypassed well and the switch doesn't break it'd be ok

Hmm. This does'nt want to work. I grounded everything considering i got shite jack sockets from maplin, even the case and pot all back to the dpt switch, but im still getting a hum (like a ground problem).

Just looking at this again, i know the guy gets his numbers jumbled up (which did'nt help) but the 3rd lug on the pot doing nothing, is this right? There's also no ground with the mini toggle so i assume the case is linking that in?

Here's a map for all the connections from the switch.

Switch lug 1/2/5 to tip of Out jack
Switch lug 3 to center lug of toggle switch.
Switch lug 6 to tip of RTRN jack.
Switch lug 7 to ground
Switch lug 8 to middle lug of pot.
Switch lug 9 to tip of In jack

The ground wire from lug 7 can go to the sleeve of ANY jack. The enclosure acts
as common ground for all jacks. In this pic, it's connected to the sleeve of the
Out jack. You can also see the orange wire from lugs 1/2/5 going to the tip of
the Out jack.

I found this diagram aswell:

Thanks dude. I'd like to hear Bencol's opinion on the original diagram as he said he had built one, also Mike's of course.. because another guy i spoke to said he could'nt get it to work either. If its shite i might use yours.. goddammit, drilling fucking cases out for the lulz

I know how you feel, it's so frustrating. I went to maplin today to get all the parts but they didn't have the right footswitch. So luckily I got to hear about your dilemma before buying parts for something that doesn't work.

I think I'm gonna make the one I posted. I'll report back.

I don't remember having any grief - Rhys has got it now (I felt guilty about the upcoming flip of the Tokai) - get him to post gutshots maybe? There's a weird little jumper on the switch, if that helps?

Fran · Post by **Fran** » Sun Jul 18, 2010 11:36 am

I got that weird jumper in, gonna try bypassing the mini switch this afternoon to see if its that. I'll take a gut shot too.

Fran · Post by **Fran** » Sun Jul 18, 2010 4:04 pm

Here's a picture, still no joy. The jumper is in as stated, my mini switch is different but changing things there effects nothing and it still sounds like a ground issue. Because Maplin sell useless plastic stock i've had to ground each socket with the case back to the DPT switch.
These jack sockets, the lugs closest to the nut is the ground and the ones nearest the tip are the hot i assume?
