Zvex - Lo-Fi Loop Junky [traced]
Information
I like to see the inside of this looper. Anyone has gut shots or schema?

Looks like The Tone God's Payback.

There was this french website which had almost a project for it. Let me see if I can find that link.
Here it is:
It's not a clone whatsoever, but it might do it.

I don't understand the allure of this pedal at all.
The sound/features are something I'd expect out of a under $20 DIY project. It does 1 loop, no overdub, no reverse, AND sounds grungy. Mmmm.
Now, if there's a doable DIY version I'd probably build one(minus the modulation).

Yeah, I think the problem (although I think I could live with it) is the lo-fidelity of the recorded sound.
Is there any other way to do it, without that lo-fidelity? How 'bout digital?

it looks like it.briggs wrote:That looks pretty intense. Are those resistors soldered under the chip?
i think what he did is used IC sockets around the resistors and overlay the 28-pin analog sampler IC on top. He likes to do these sort of tricks to save space. I love to see one in more detail though.
I saw the payback at diystombox but never any clips, so i can't tell what it sounds like. Probably lo fi.

That's a pretty clever way of doing things.... Gives me a bit of an idea!
As always with zvex - the beauty of his pedals is in the marketing. He knows how to sell them..... Why buy one of these when you can have a great Boss sampler for the same (or less £)? Because it's bootweek! Kudos to the guy for working it all out

i just want to see how he put this looper together and what chip he used. For $160, you can buy a a boss rc-2 that in every single category except for loop modulation blows it out of the water. But yeah it's the boutique thing.briggs wrote: Why buy one of these when you can have a great Boss sampler for the same (or less £)? Because it's bootweek! Kudos to the guy for working it all out

It doesn't seem worth it for the money I have a line 6 DL4 or whatever it's called. It does an imitation of just about any delay you can think of. It also records 14 seconds of audio, plays it forward, reverse and half speed. Allows over dubs.
Zach gets bashed pretty hard around here sometimes. But to his credit I have to give him props for making something like this into a real product and fitting it into a B box with no SMD parts. You have to admit he does a pretty good job. I have a ringtone and it's pretty amazing what he's fit into the box. The thing sounds pretty good too. He's solved all the problems with carrier bleed. It's a great ring mod. Original concept also.

Any of the ISD1xxx series chips should work. Small bear has ISD1020APs, which are also 20 second chips.General Guitar Gadgets wrote:"- Inspired by VZex's LoFi Loop Junkie and
- Based on 20 second voice recorder chip, Winbond ISD1000A - Why, because I had one. Although they are obsolete, some RadioShack stores still have them (276-1325) in their discount bins.
- Three pots: Record Level (to optimize the signal level going into the ISD1000A), as well as Playback Level and Dry Level.
- Two footswitches : Record/Play (lights red 'Record' LED in record position), and On/Off (lights green 'On' LED in on position). 'Record/Safe' switch (toggle or slide) helps to prevent over-writing saved loop "

They are produced by Winbond (there's an overview). They also work up to 12kHz if you can get the right one. The reason for the limitation is these chips are intended to work as voice recorders in answering machines and so on, no hifi.
The Lofi Loop Junky is just . Build something inferior and then call it a feature...
I'm planning on a µC + RAM looper including several recordings, overdubs, and so on. But that might take a little while due to general lack of time.

I see you guys know of the existence of the Payback. I have made a schematic for this one, and it worked for a short time, as you can see in the video. At the moment I am having noise issues in bypass. There is some humming like sound that dissapears while recording and playback, but is always there when the pedal is in bypass. I'm was debugging it with tonegod, but he hasn't replied to me in over a week now.
C11 and C12 are uF, not pF as I mistyped. And there is a 100K resistor going from pin 14 of IC2 to ground (the ROSC)
This is from when the pedal worked, at the moment there is that noise issue that just appeared.

Bazinga!
These are all awesome work alikes. thanks for the contributions. i found this one a few months ago: http://www.instructables.com/id/Looper/ it seems cheap and simple. i am not sure if it works because i never built it. if anyone is successful please let me know. thanks

okay, just assembled one of these (the mobius trip looper) and she's a no go. only changes I made were to use an ISD1110P, and I was a bit unsure about the 4001 chip (I couldn't see exactly what I should be looking for) so used a CD4001BE.Ghengis Jung wrote: Any of the ISD1xxx series chips should work.

assuming I got the other parts right, should I expect this to work at all?
I get no guitar signal, in either record or playback, the red LED comes on in 'record' mode, but the green fails to light up in 'play' mode. I can post voltages on various pins if that would help?
I notice that I lose guitar signal after the 1st 100K resistor (using an audio probe), is that to be expected?
thanks for any help in advance

Ok. Now that the Dean Hazelwater Mobius Trip Looper project at GGG is discontinued, what's my best bet for finding a PCB for sale that functions like the Lo-Fi Loop Junky?
Information
I'll be releasing a project and PCB for the Mobius at some point. I've had a design done for quite some time, but it's not working as of yet. Once I finally get around to ironing it out, I'll post the project here (which will include PCB artwork, of course). My layout is quite a bit smaller, too.
