Fixed it!! Cool. I’ve got a Chorus pedal I built it worked!! Then it didn’t! It seems like there’s a bad solder joint or something is grounding out on the enclosure. I squeeze the box and it’ll work. Let go it doesn’t. It’s not a bad ground because I’ve got to squeeze the box not just touch it. I’m definitely thinking bad solder joint. Just like in this video!!
Thanks for not sugarcoating your videos. I like watching your videos over many of the others. Do like watching 2 others that you have mentioned on your channel.
Totally different question. Have you had any experience with the old National GA920P Solid State Amps from Japan? I picked one up and need to see if there is any hope in bringing it back to life. BTW love your channel! Peace! Alex
The build quality looks good with standard parts. The sound doesn't even come close to the Morley Phase pedal from the 1970s, At least, you made it work.
Just before 16:51, you rotated the pot and manual phasing occurred. That means that the LFO isn't oscillating. Since we heard the manual phasing by turning the pot back and forth, that means the "phasing path" is working which means the 2N5952 (IIRC) FETs and the 4558 op-amps are all good. The LFO is not starting for some reason - the problem lies in there. Use your O-scope to poke around and look for the LFO signal... it should be on every one of the FET transistors' gates. Pin 1 Gate, 2 Source 3 Drain left to right on a TO-92 package FET. The LFO runs in the few-Hertz to maybe tens-of-hertz range of frequencies (my mind is mush to tell you the range off the top of my head. That VR in the circuit is prolly an LFO speed trim IIRC. This generic phaser is likely a copy of the tried and true Phae 90 style topology using standard op-amps and FETs rather that OTA-style circuits of yesteryear. I wish I had you on speed-dial as I'd help your foray into my wheelhouse with better info that I'd lookup and give ya. Dan Gibbs :) (Owner of 1500+ effects pedals....half-or-more of them repaired by hand)
well, I'm now at 19:51 and that pot appears to set the "bias" operating-point level for the 2N5952 FETs. Great Job BL!!! Lucky is my middle name outside of Providence!!!
Hello Doctor, I'm intrigued by the little plastic socket you use to pull the input jack nuts off. How can I find such a device? Thanks for the great video as always.
@@TheGuitologist Thank you! Uncle Doug has been mentioning you to me for ages and I only just started watching, spent all yesterday absorbing your excellent videos. Actually went to a guitar center today as a result and checked the dumpster but they locked it all up :( lol
@theguitoligist-😂 I laughed every time i read the title..it would be cool to make a vid showing us things to look for when pedals arent working..i bought a delay pedal from mercari and it didnt work when it got to me..if i would have known things for me to look for,i would have opened to see if i had the option to fix it..thanks for the vid brad
Thanks for the unedited video! I also have a penchant for cussing at inanimate objects 18:43 😁. So far, I don't remember it ever helping, but now I can honestly say certain (the only) aspects of my own repair endeavors are just like Brad The Guitologist 🤣. BTW you (The Fixologist) inspired me to drop the deck off my 16 year old lawn tractor and replace the belts and the broken deck cable (blade engage). I'm much better at meathead repairs than intricate electronics. But MUCH cussing still took place😄👍🍻
PCB’s are great. Some old ones are. However, some new ones aren’t. When you have to work on them. Why I still like the old things. Much easier to work on.
I bought a Danelectro SurfWah pedal thingy. It never worked. Until I plugged a vintage Silvertone Danelectro guitar into it. It worked very well. I assume it was because the impedance matched. Something about the resistance of the pickup. There you have it
they are almost certainly fixable. A decent multimeter and common sense can really get you a great start, and uncle Doug videos will take you as far as you can ever desire
I dont know if you have one but I have a simple looper pedal i use at the beginning of my pedal chain which sounds wrong in theory but its handy for messing with pedals without trying to do two things at once. Handy for stuff like this too.
Hey Brad I have a question . Have you ever tried “Wire Dryer “ for a pot lube ? It’s an automotive product to dry wet distributor caps. That leaves a light conductive oil behind. 🤷♂️
I just bought two new ones in a row. Expensive enough, but neither one is hot enough to do neat work. Back to my bernzomatic pens, which work great, I just need some new tips.
Im not a pedal guy but, that had a good sound that could. be useful.To me listening on a cheap phone I almost could hear the rolling. effect of a leslie speaker. My favorite tone is playing a les paul with classic humbuckers through a 70s deluxe reverb, or a tweed deluxe, if you can set the volume up just enough to find its sweet spot right at break up. To me pedals are great when you are playing at low volume.All right I will stop rambling! Good save, repair, as always thank you for the Vids!!!
on the phase 90 the trim pot has a cunt hair of range its needs to be adjusted between almost the whole range doesnt work you gotta get it in the exact little spot seems like this one is the same
Whats this? The Fixologist fixin stuff on that amp guy Brads channel? Wth? 😅 just kidding bro great video. Knew it would be some dumb dumb thing wrong like something that got missed or not done correctly.
you know brad i bought a eddie kramer foot pedle real small like the one we are watching you fix mine does the same thing lights up but no sound or effect
I like watching your videos because you don’t patch yourself on the back all the time you’re a very nice person. You’re the expert. Everybody needs next door love watching your channel. I always will. You’re the best man really mean it. You’re the best.
Two lfo's. Hated this pedal needed to be modified but I've found myself putting every ing in front my my wah in except rever deadly amd chorus. And the gain pedals in front of my amp and after the wah.
I'd have done the same. I'd checked continuity and touched up the joints. I fix broken electronics as a hobby to keep stuff out of the landfill. I've got a bunch of germanium parts and such Brad if you wanted to make some pedals
I don't understand the affection to cheap crap. The "everyone has to have everything despite their income" makes me puke in my mouth a little. I doubt you're any happier if you own a cheap pedalboard instead of one or two pedals that cost as much. Jimi, Jimmy, David, Sid, Rory, Keith, Kurt, Tommy, Noel, Neil, Dimebag and Eric weren't hindered by having only one or two pedals. I bet they made more significant music (and got more chicks) than someone with temu pedalboard.

That trimmer is most likely a Bias trimmer for a transistor, just like in a phase 90. if they are out of the "sweet spot" there is no phase change.
I LOVE THE TITLE..

Did you check power supply polarity. This when wrong can damage pedal.
More likely back into a new box and on to the next customer
The builder used a red LED. Everybody knows that amber LEDs are phase LEDs!
This video empowers me to try to fix things that I might normally pass up. Cool sounding pedal too!
Thanks for sharing your whole process.
Those surface mount pots are known for crappy connections and a lot times just turning them cleans the wiper. Great job.
Thanks Brad 👍🇺🇸
Another job well done Brad.
Hey mine didn’t work either now I know why! Thank guitologist!
Thanks for the video.
dude the new camra works good focus is great
You take on every challenge. I myself would've thrown it into the lake. But you've shown me another path. Thanks
Oregon approves.
What did the lake ever do to you? 🙂

Where did you get the wrenches for jacks?
any music store or website. Sometimes they come with an output jack or such when you buy one.
Greetings from Spain, peace for all !!! And pedals without smd, hate that shit creeping into our guitar world Should ony be in computers stuff

Because fux it I love it hahahaha
Nice to see another Kline tool user. I was a telephone tech for over 25 years and if I learned anything, it is that Kline makes the best tools period!

Or he could just watch an uncle Doug video. He has several addressing envelope filters of a few varieties
The LFO was not working or not connected to the JFETs.
Technically for the price it's a throwaway pedal like some of the danelectros.
Very hard to work on..
LOL . . . this is what I do . . . if it doesn't work, open it up 😎 . . .
I gave up when surface mount took over the industry.
That camera view/lens is so damn good man 🤘😎👍!!
sounds good dude
Always late. 😂😂😂😂 that’s ok now I can pause and not miss anything.
Nice! Gotta love the simple repairs!
best title ever
On a different note, You were correct on the (what the hales) vs the neighbor
Of course I was. I'm a great judge of character.
lets say the trim is 100k on the phase 90 it works when the trim is diale between 50k to 51k everything out side of that makes the phase not work
So that little tweeker wasn’t making contact until you tweeked it? 😂😂😂 Awesome!
Psyched for Brad live!!
Let's go Brad 💪🏻
I can really see that board very well! I usually cannot read the numbers on components in most pedal vids. Great job!
the markings, lines and color tell you what you need. Nobody can read that tiny shit

Have you ever thought of using a looper pedal, and playing a simple chord progression while troubleshooting amps and pedals?
You could master a Rubik's Cube in short order if you haven't already.
You don't "master" a Rubicks cube, you learn the algorithms and sequence orders 🤷🙄
@@RobBob555 That is mastering it fool.
Way to go Brad fixing is fun
los like a phase 90 clone 4 transistors and two dual stage opamps
Nice Nails Brad !!
Brad -I really need your expertise and help. What is a good email or way to contact you direct? Thank you! Lee
Wow they could have put a knob on that rate adjustment
Bias adjust is what that trimpot is changing. Between that and the FET leg, it's no wonder you weren't getting anything.
Open that thing up dude!

We're all just tryin to get a little deeper.
Actually I am usually trying not to bruise and internal organs.
I wish I knew how to fix some pedals that I have, if they are fixable.
they are almost certainly fixable. A decent multimeter and common sense can really get you a great start, and uncle Doug videos will take you as far as you can ever desire
Hi Brad, you could modify the effect by adding a potentiometer to vary the depth, that would be an improvement.👍
a push pull pot so you can linger on any tones that catch your fancy
I dont know if you have one but I have a simple looper pedal i use at the beginning of my pedal chain which sounds wrong in theory but its handy for messing with pedals without trying to do two things at once. Handy for stuff like this too.
