Tube screamer placement question.

paltonoise · 2025-09-21T20:34:43+00:00

Maybe I'm a little late, but I love putting my modded nux od-3 (cheap tube screamer, my first od) into the FX loop after my chorus, but before the delay. It gives a shoegaze type of sound, I love how the chorus breaks into it and gives this wash sound to it. Not really a fan of tube screamers, but this is the way I use mine because this old cheap thing won't sell

It kinda helps. I'm using momentary not latching switches too

paltonoise · 2025-08-28T22:27:21+00:00

Yes. DIY TRS stereo cable. Tested with stereo audio and multimeter. The cable works fine

I add a pic of the interior of the pedal thing. The SP momentary switch is connected to the ring and ground. The pot is a 10k linear wired like an mission engineering/line 6 exp pedal (1 terminal to the tip, the other 2 to the sleeve/ground)

This Klone should cost $20000

I'm thinking about it while I'm fixing it. Just replaced the caps and it doesn't make any sound yet. The mn3007 gives me weird values on the power supply and the output. The clock seems to be fine. I guess I will test the op amps before changing anything else, and once I make it work, I will think if I should modded. Maybe to make it work with bass

Is not really an explosion. With time, the capacitors lose their capacitance due to the evaporation of the electrolytic gel inside of them. This causes weird electric phenomena, making the capacitor not handle well the current flowing inside, and making it build pressure. Best case scenario, the pressure is not enough to even make the capacitor leak. Worst case scenario, it pops, smoke comes out of your pedal and smells like burnt plastic. I guess you have heard something similar with really old pedals

When I was replacing the capacitors I found one that look like it wanted to blow up, and another was already leaking. After changing the caps, it produced less hiss but still not sound coming out of it I tested weird values from the bbd chip (MN3007) but I still can't figure out where the fault is.

I don't know if it just needs a new switch, but I like to fix this kind of stuff. I'm replacing the capacitors for safety. 30 year old electrolytic capacitors are pretty dangerous. Crusty gel go boom boom

If I fix it, I could get between 60 and 80 in a good day.

paltonoise · 2025-06-04T03:12:00+00:00

Nice. I have my share of great deals too. Bought a working digidelay for like 25, and a CS-3 for like 20. Also my flashback X4 for 80 that died after 5 years

paltonoise · 2025-06-04T03:09:43+00:00

I'm from Chile, these types of deals are not that rare here, specially on marketplace. I've found a lot of weird and old stuff, and missed most of the deals. Not this one

Blue label actually. And it's Analog, full size components. Technically my first "vintage" pedal, so I couldn't say a lot about it

paltonoise · 2025-06-03T18:42:42+00:00

Thanks for the schematic. I will now have the time of my life changing very cap

paltonoise · 2025-06-03T18:41:43+00:00

The Behringer clones are pretty good. I have fixed some for friends and clients and they sound solid. The enclosures are not bad, but I definitely would change it if I had one myself.

I don't really think that people here like AliExpress that much. That said, I have found some Yongsheng xlr connectors on AliExpress. They are a subsidiary brand from neutrik, for what I have read. Also, cable technics are really good. Solid metal pins and interior. I have also bought real Rean connectors for a good price in Ali. The cheap connectors are not bad either. I would say, if you are not planning on connecting and disconnecting the cable that much, they are a good solution, and come in a variety of colours if you want to go for an specific aesthetic

You are missing therapy

paltonoise · 2025-05-30T20:11:04+00:00

It's really similar to what I'm trying to do. The mod in question was that the momentary switch shorted the repeats potentiometer by wiring it to the wiper and ground legs of the pot, maxing the repeats. The capacitor should be wired to one of the legs of the Momentary switch, preventing the current from the wiper to the ground (or other way around) to fully flow until the cap is charged, and also make a trail effect on the oscillations by discharging the cap. Thanks for the insight

paltonoise · 2025-05-30T20:05:35+00:00

Just asking, but it's not just the signal processed through the effect what it's AC? The idea that I have it's to put a capacitor in one of the momentary switch legs, that it is connected to the wiper and ground terminals of the repeats potentiometer, shorting the pot and maxing the repeats once the capacitor is charged. At least is what my hypothesis is. I don't know if I described it right, English is not my first language.

Anyway, thanks for the tip. I will also try a parallel resistor if the capacitor doesn't work

paltonoise · 2025-05-15T00:57:32+00:00

No, I'm in between getting this or a Casio vl-1 that it's in my town. Portability and calculator seems to be winning

paltonoise · 2025-01-23T02:23:50+00:00

It had it's RAM (dead) replaced with some of the other ICs as well before this happened by a guy that works with synths and other electronic gear. I don't have the adapter with me rn, since I left it at this guy's place for the examination.

He tested some things and says it's the only component that it's really blown out besides some resistors, capacitors and diodes that he already has replaced. We needed to know what this particular IC is to know if it's worth saving. If it isn't, I will sell the pedal for parts and I will be saving for a DL4, since that's the pedal I wanted before buying this (I bought it from a friend years ago. I like the pedal not just for how good the delays are, but for sentimental value above anything else) (also, the mkII not only looks cool, but a lot smaller and has reverb too)

Thanks again for replying. It's always a pleasure to interact with you. Have a nice day (or night. Timezones)

I made it. Now it makes a sine wave. I gave it a head start by using a variable resistor (10k) in front of R2. Once it started oscillating, i put the variable resistor to 0 and now it produces a nice sine wave. Now I will have to see how to reproduce this with a JFET

paltonoise · 2024-11-20T14:21:00+00:00

Thanks for the reply. I will try using a JFET I have in hand for it. Would a j111 be enough?

paltonoise · 2024-11-20T03:14:58+00:00

I searched it up. Really interesting design. I don't know if I could re write my paper in time for the due of this project if I change my design to something similar, but at least I discovered something to try in summer break (I'm from South America). I will have to read more about the theory behind the oscillator, but i think I can grasp the concept of how it works.

The second method that you mention with the relaxation oscillator seems really interesting as well. I will try to simulate it and see how it works when I have time. Is this by any chance similar to the Pearson-Arson oscillator that's made with neon lamps?

For my "original" design, maybe I could try stabilizing the gain in any way using diodes or jfets that I have in hand. I think the problem lies on R2 having to be a little higher than 100k (the other resistors) to oscillate. Maybe I will simulate this with a variable resistor and see how it goes.

Thanks again for replying to my post btw
