- Mark repairs a 1979 vintage guitar effects unit, which features a super rare Bucket Brigade Delay chip - the Reticon SAD1024. It doesn't go well, and did Mark get scammed???? FAKE component alert!
Here is the link for Andonstar HD Digital Microscope - as featured in this video:

Wow, not only an electronics genius, but Mark also plays guitar 👍👍👍
Yes, I was impressed, he's awesome!
Shreds, slays, treats the women right,
Inspired by Kirk Hammet
I must admit I had a Bubbles moment there.
soldering skills say this is no genius. also why does circuit say copyright ralf metzger, and nobody notices the breaches of IP.
Watching People actually manefacturing stuff instead of buying or outsourcing is awsome!!!! please more!!!!
Is there no end to your talent. I’m very impressed with your efforts on this one Mark.
Just what every electronics workshop needs, a test strat.
Before this channel, you couldn't easily find it all together in one person: knowledge, charisma and sensibility. Mr Mark, you're all of those things, your channel is one of the best here and I look forward for more from you, sir. Well done!
Etching your own board, finding a functioning chip replacement. You're a beast Mark , thank you! I've been watching your videos for the last several evenings
“Better discharge the static…Not that there is any in this country” 😅
Static in every country and your country shines out in fiddlers, guitarists, unt Der flooglewelt.
I can build and troubleshoot electronics, and I have a lot of fun with it. However I can testify that Mark is on a completely other level. Great to witness this proficiency. I am also impressed with the cheerful easygoing attitude. Cheers Mark
The fake chip has marks on top showing the original top surface was ground off. The half moon indicating pin 1 is also shallower than normal. Amazing effort rolling wire to make flat pins!
Not as consistent but an iron strip and a hammer will also do the trick. But Mark's way is more elegant and professional.
@@paulmichaelfreedman8334 You could also use a socket with long pins
@@tim0steele I'd have just made them longer and soldered them into a vero board, them solder the pcb on the other side of the legs, and snip off the legs to the right length. But to each their own of course. Mark's skills are top notch.

That’s why I loved fault finding as nothing quite replaces that buzz you get when you switch something on after a repair and it works ! It takes a certain type of person to be a technician.
It’s addictive lol. The more complicated the repair the bigger the buzz.
At nearly 70 I can’t do delicate work anymore due to trembling hands and it’s so annoying, but I still have all the test gear !
@peterhyams6824
Just a thaught....... you could consider teaching a youngster who wants to learn, and he/she could be your hands?
Im sure you could still get work if thats your profession, as mentoring someone is as though you continue your work through someone else, and eventually you could hand over your business to that person who would continue to provide help to your community 🙂 ?......
Never seen handmade pcb's before - I've just been educated AND entertained! Thanks man, you're a modern day McGyver!!
Glad you liked the T strippers! Ideal entered the market with abrasives for DC armature maintenance and branched out. Glad you got some nice sounds out of the Mistress.
Just when I think you cannot impress further, you push the bar even higher. Your channel is a never ending source of education and entertainment. Thank you for taking the time to make these videos Mark!
The SAD1024 is virtually unobtainium. They sound great for guitar, though. I've made a pop-in replacement using more modern chips, as have others.
They're obtainable, just not at a pricepoint that's comfortable for people who don't really, really, need them.
to align all the legs before soldering them you can use a spare socket and press the legs into the spare socket and then solder all the pins at the same time.
Is there no end to this man's talents ...........................................
I used to work in a small music store in the 90s, and I had to deal with very similar repairs as this one. To be honest, I would have just hard wired the different chip with jump leads. Crude, but effective.
I like your way better.
It’s always a great day when Mend it Mark uploads a new video. Thank you!
“Night after night, who treats you right?, Baby, it's the guitar man”. 🎸
Is there no end to your talent ! Last video I saw you replaced the writing on a Technics amp as the cleaning foam you used erased it off the brushed metal plate on the front! And now you're designing PCB boards and replacing an IC and using a modern equivalent - somehow making it work! Then to top it off... a bit of guitar at the end! Genius! Wished you were closer, I'd love to come to your workshop just for a visit - and maybe learn from the master!
Подумал - Сашка Лаэртский, ан нет. Но когда в конце заиграл на гитаре - засомневался ) Спасибо, вы очень крутой спец!
That really took me back to my CDT lessons, I loved making printed circuit boards like that 😊
Wow solid work! 😀 Lovely bringing a device like this back!
As usual - very clever and resourceful repair. I think I might have added a power light as a bonus.
A 12 volt led doesn't cost the eart, and a hole isnt that akward to drill with a "splodge" of glue 😂😅😂😅😂
Hi Mark, as a fellow engineer from Walsall I just wanted to thank you for the enlightening videos ,keep up the good work, every day is a school day 😆👍
Any machine you don't have?.... lol Thank you Mark for letting us walk along with you on these projects. Sorry about the fake chips. Really enjoy watching you work your magic. Thank you from the US!
The counterfeit market makes things super frustrating! I loved that you made your own PCB for the replacement.
Now.. thats what I'd call a professional repair.. lots of time and effort spent..
my main interest in electronics is audio..guitars, pedals amps, mics, preamps, mixers..love these ones
Jasus! As always an amazing repair and engineering work Mark.
First time I’ve seen you play, no end to your talents.
You’ve opened up a big can here Mark with your work around.
You’ll be bombarded, I’d like to jump in first, will you make me one of those boards for my HH Clockwork Concubine, I’m on my last 1024A
Might try buy some 512s as spare.
Keep up the brilliant work.
Thank you
Trev
watching you work your magic, i regret not getting into electronics when i wanted to, as a young electrician apprentice. Now im just a sparky, but playing at fixing amps as a hobby, learning from you at nearly 50. Thanks Mark
11:12 Thanks for the great tip of floating the non-drilled single sided PCB on the etchant!
What an absolute pleasure to watch somebody who actually knows what they’re doing 😎 Shame you’re maxed out with work, Mark - I’d love to send my old EHX Deluxe Memory Man in…
... and you're a muso as well! I'm more impressed every day Mark 😆 Possibly the most impressive tech repair channel ever mate, love your work!!
That old peddle has a nice warm sound to it. Your nice little modification board was the most interesting bit of that process. Nice work.
You have a lovely workshop, it would be interesting to do a little mini- tour of it in a video one day. BTW - I love your guitar, lovely colour.
I like to leave the excess photoresist on to keep the tracks from oxidising. Not that it does any harm, but it looks nice that way. But I rarely do boards at all these days, the costs of production boards with soldermask and silkscreen and everything is just too attractive. Still, the capability to spin your own boards is great for those times where you must have something _today_ . Anyway, this repair was top notch. Please explain how I can like this video twice!
Make 2 accounts, one on laptop/pc, one for tablet and one for phone and click like from all 3 machines 🤣🤣🤣🤣🤣
Brilliant! Love watching your repairs - its the chuckle that's the icing on the cake!
Ahhh Mark, I have to go to bed ffs! Oh well. 30 minutes less sleep can't hurt.
@monsieurtechnical it's not his fault anymore now, of course I fell down the classic youtube rabbit hole 😁
Any other technician would say " irreparable", but not Mark. Greetings from Brazil.
...you can also play guitar. That's awesome. I've been watching several videos. You are a GREAT technician. They are hard to find anymore. You have great equipment and great instruments. Congratulations.
Im so glad i found this channel. Please more of these. So cool.
I've got a late 70s, Mistress (the 2x9v) version that I got as my first ebay purchase back in 2004. Sold as "untested". When it turned up no sound. I found a pedal repair guy who thought the same as me that the SAD1024 was dead. Luckily the only issue was one of the 741s had died. He replaced it and it was good. I really needed to get that pedal down from the attic to test it as it's been 10-15 years since I last plugged it in
Haven't seen that pedal in many, many years!
I've watched many of your videos Mark .. and there's always another bit of kit! Wire roller ... chip straightener - awesome
Brilliant, I started 40yrs ago as a pcb process engineer, that was genius…
Great save using the SAD512 on a custom PCB. I liked the flanged minor sevenths too.
Excellent fix, as I recall Electro Harmonix made two versions, the Electric Mistress and the deluxe version, I have owned both, way back, trying to simulate a Leslie organ cabinet, I was given one that had been installed in a box, for free standing rather than floor use, I sold it for a considerable amount, maybe somebody was buying it for the components !
Man I did not predict that a home made circuit board would be part of the fix! That’s truly next level stuff!
I’m sure you have no shortage of things to work on but the guitar community are predicting a huge drop off in the number of people capable of repairing tube amplifiers in the next few years. Would you consider making some content tackling common issues associated with guitar tube amps?
Respect, this brought me back some solid memories of lessons creating boards using nasty chemicals, awesome!
I've used Ideal Industries strippers for years - fabulous tools. People seem to like the auto clicky things nowadays but for the old fashioned types these are reliable and sharp.
This video brought me back to 1982, I was taking an electronics class at college and we had to design and etch a rather basic circuit board and then build some device. Radio Shack, in the US, had everything I needed. There was a marker like pen that put a resist compound on the board, that created the traces. Any copper that didn’t have the resist marker would be dissolved by the acid.
Well done sir ! I’ve also had the pleasure of buying fake chips . Always disappointing. And the sad part is they weren’t even that expensive of a chip or very rare to begin with . Just never know what your getting anymore!
Demand your money back or leave bad feedback or both
Just wait until you receive fake chip sockets!
You are a pretty incredible dude. You've reignited my love of electronics, that is, the knowledge of each component, identifying circuits. Keep up the good work.
Who would know that one of the most involved repairs I've seen you done would be of such a simple circuit! Always a pleasure to watch your vids Mark
Chip straighteners? Who knew? That was really interesting Mark,even though a lot of it was over my head🙄Nice Strat BTW
I know that feeling when you plan and prepare everything, but at the first switch - things don't go to plan... Kudos for sticking with it and working out the solution!
Amazing video with so many twists and turns! Let’s make a PCB and get the Strat out
Amazed that you went straight to making an adapter PCB without testing the modern chip on breadboard or similar. You know what works right away.
Multi talented, very impressive. Thanks for the great videos Mark. Keep 'em coming.
Astonishing knowledge and skill - Brill
This man tools. Seems to always have the right machine for the job.
Wow, last time I did this was probably 40 years ago ! You rock!
One of the most involved music videos I've ever seen.
Awesome video as always.
Electrician for over 20 years and those ideal strippers are the only ones I will use. Always bugs me to see electronics guys use crappy strippers.
Mark, Thank-you for your response on your Cats name! I just started watching your video's and now I can't stop! So interresting. I have those wire strippers myself, Their awsome! I live in the United States, In a small town in Northwest Ohio Called Maumee. So your vids reach far and wide! Keep up the great work! Mike Z.
Some good fishing there during the Maumee River Walleye Run!
The guitar was the cherry on top of the cake!!
It's fascinating to watch you repair things. Thank you for sharing such a entertaining video.
Those two smaller caps looked a bit dodgy too, was surprised you didn’t replace those too.
I am impressed with your road to succes towards half a Mistress with satisfying result!
It's fascinating to watch you repair things, thanks for your videos !
Omg, nice guitar! This was a fun episode.
You are a genius, Mark amazing skill level
Great work again. And didn’t know that you can play guitar as well.
Get yourself some mn3007 and mn3009. also, you can get mn3010 if you can find them. The mn3007 is a 1024 stage and the mn3009 is a 256 stage. You can find both of these that are new and currently manufactured. I've given up on getting the old sad parts so now I build adapter boards for projects that adapt the mn3007 to work in the same circuits that used the sad1024. Most flangers and/or chorus pedals use the 512 stages in series or parallel so the mn3007 and mn3009 can be adapted quite easily with minimal modification. I learned this stuff when building clone pedals like the A/DA flanger. May help others in the future when building or repairing pedals like these.
Fantastic video. Well done. Mike Matthews would be proud!
This is more like a manufacturer workshop ( milling, drilling, fabricating etc). He must be a genius!
Gday Mark, bought a Caps set for my amplifier and a supplier from bulgaria, was fast and all looked fantastic, until I sent a pic to my brother who got the same only to be told by his elec tech they were fakes. 😢. Disappointing when you expect something for the money. Just as well we didn't get them soldered in! Enjoyed watching you vid. Cheers from Tasmania Australia a long way from Bulgaria!
Excellent modifications....
Yeah magic Mark time!!!🎉
Really enjoyed the design and build of a “custom” chip👀 superb.
Mark,
Really happy that you found the wire strippers useful! I've had a few Electro-Harmonix gadgets in my rock-n-roll days. LBP-1, and a Mike Matthews Freedom amp. Freedom because it also was battery operated. Mike Matthews was the founder of Electro-Harmonix back in the70s.
Thanks for the acknowledgment. Solder on!
Love to read those schematics with you. Takes me back, very very satisfying.
Musical Mark Mends it. Well done ! 👍
Thanks, Mark. I love your presentation style and excellent production qualities. Cheers!
Thank you very much! I’m due to film a new one over this weekend- I haven’t decided what it will be yet, there’s no shortage of gear to fix! Cheers! Mark
It's great to watch a genius at work. A man of many talents.
just incredible
Your process for making these videos is spot on. I can't tell you how much I enjoy your work, Mark. The breadth of gear you cover is awesome I can honestly see you going a long way!
My dad has the same pair of Ideal wire strippers I used my whole childhood and they are still just fine.
A man of many talents..............
Way to go! You could market those SAD512 breakout boards!
That was hot. Takes me back several years when soldering every day
They used to make DIP socket extenders like you made; sixteen double ended posts held together with PE plastic. Don't know if they're still available, as I haven't done bench work for years. It's good to see I'm not the only one that clumsily burns myself. I hope your customers appreciate how far above and beyond you go.
Hi , I just want to say how much I enjoy watching , you are brilliant at making the very technical repairs interesting and fun.
I didn't know you could play the Guitar,a bit. - Greetings to the best electronics Craftsman, We see you often.
Very nice! I've built the "Electric Lover" clone a while back and I remember very well that adjusting the trimmers brought it to life. One of the more complicated builts compared to my fleet of DIY drive pedals.
Analogue systems have zero latency apart from intended delay. That is a major asset. It comes at the expense of noise.
Remember buying one on these NEW!! Absolute cheap rubbish! extremely noisy! Nice work Young Mark!
sad1024 is the holy grail - dave gilmour used this modulation effect - the lectric mistress - its a great sounding pedal . i have a reissue - its a great pedal . i have a bad bbd chip in my roland jc50 ...
Mend it mark - now with music 🎸Then it can’t be any better 👍
Awesome example of raw engineering.
