1977 Morley Evo-1 Oil Can Echo-Delay Pedal......Complete Overhaul & Test

Jack & I were flattered recently when the Morley company asked us to restore one of their 1977 Echo-Delay Pedals, which uses a Tel-Ray-style oil can unit to produce some really incredible effects. This video documents the entire procedure including disassembly, cleaning, reassembly and repair.....with with a detailed discussion of design and operating theory, history, and an audio demonstration of the echo-delay effect in stereo.
In addition we will be visited by Ollie, Jack, and KC at various times during the video to break up the monotony ;)

@@UncleDoug When I was in my late teens and going to community College I worked anodizing small aluminum parts. That was 48 years ago but I still remember how. The part was made the anode and immersed in a cold dilute solution of sulfuric acid that was in a lead lined tank. The lead liner was made the cathode. A specific amount of direct current was applied for a specific amount of time to make a certain thickness of anodized aluminum. There were tables we followed but we would also measure the thickness with a micrometer. The result is a layer of aluminum oxide that's very hard and corrosion resistant.

[@audiotechlabs4650]

The history of Morley was illuminating! To have the current owners of the brand choose you to restore this effects pedal is a no-brained. There are other shops/individuals who could do the work, but you are who I would trust, especially after discovering the repairs someone else tried. Your brain works in a way that won’t let you do things that are not the most correct way. Your brain also has the ability to solve problems and overcome obstacles. I had my headphones on and the dry/ wet stereo signal was dramatic. I panned from left to right to prove the true stereo separation. When panned to the middle, the effect was a little hard to distinguish, but isolating the wet channel, proved the effect. I can only imagine what it sounds like in a room with two amps, one on each side of you! The computer program for seeing the waveform, solidly puts you in the 21st. century. Who says you can’t teach an old dog a new trick! Your compassion for the cats is fantastic! We have cats that have come to our home on their own and we do similar things to provide a loving, safe place to live a good life. Love from NW Colorado. Thanxz

Uncle Doug you have explained a mystery that has lived with me for decades.. In 1975 as a young professional guitarist, I was employed to demonstrate the full range of Morley pedals for Australian distributor.. They gave me the full range for two weeks prior to come up with some usable musical demonstrations. It was our first musical trade show .... This pedal was the hit of the show!! It stunned the dealers and guitarist of the day I had two Fender amps on either side of the stage sending the guitar audio delay signal across the stage !! They took orders for Morley units solidly across the weekend of the show!! Thank you greatly.. Keep well to all at kitty heaven!

Goodness, what a daunting challenge! I remember that pedal from my youth. It was the mechanical aspect coupled with the electronics that takes me back to that memory. I have never owned one of these. In fact, this is the first stereo demonstration I've heard. This episode was quite a departure from an amp repair. The engineering skill required to restore this to operating condition was a dizzying adventure. I am impressed with the approach, and especially the adaptation to effect repair of the oil can's tendency to leak. All was genius in execution. I am grateful for your unselfish sharing of the clever manner you configured this restoral. Thanks again dear uncle. You have made another uneventful weekend into an interesting, thought-provoking subject for us all to ponder and discuss. I must ask for you stay safe and healthy during this re-entrenched virus.

She looks healthy and content and possibly a little spoiled now, but it's well deserved and who cares if she has a catnip and tuna habit? I am a firm believer that animals know when they have been rescued and they never forget it. I have a couple of rescues and they are the most loyal and well-behaved dogs I have ever had. I think they know and really appreciate the value of a good home. It's too bad people can't be more like that.

Back in the 80's I found a Fender oil can reverb in a dumpster. It had not rained on it, so I scavenged it and took it home. It looked like a tiny Fender amp, about 10 X 10 X 8. Being in a band at the time, I knew being Fender meant something musical, so I opened it up and could not for the life of me could I figure out what kind of voodoo I was beholding. It didn't do anything but rotate, so it found a home in a long ago perished shed. I kinda wish I had it now, after watching this video I probably could have fixed it.

Hi Uncle Doug, in the 80's to late 90's I worked as a tech in the photocopier industry and this anodized aluminum disc made me think of the 'heart' of the copier which is a cylinder, usually aluminum with a light sensitive and high voltage electrically sensitive coating. Earlier, that coating was selenium, later cadmium and later still what the manufacturers mysteriously called "organic." In the end, it's still a piece of aluminum with a coating on it. Companies that create these cylinders (colloquially called 'drums'), could probably coat the disc or discs or anodize them. 'Love your work in restoring amps and parts like this one, that you care so much for these great dogs and cats, your sense of humour and I'm in awe of your ability to find parts, tubes & caps for all these projects.

Once it is bent or scratched basically the unit is toast and will make a thumping or clicking sound. It is impossible to get the disc flat again. I also noticed that one of the rubber wipers had a clipped corner, this was done as a repair is to reduce the surface coverage of the wiper to lessen the residual clicking or thumping echo byproduct from the rotating disc. Thanks for another awesome video Uncle Doug!!!

Thanks for your very helpful input, TTM. Our pleasure :)

Getting me thru a rough patch this week UD, thank you very much for not doing that on purpose! 😄 Carry on!

[@UncleDoug]

Sorry to hear it, OR. Best wishes for a happier future :)

[@rhoneranger549]

It was also great to hear your wife's laughter and joy in the background, and part of me wonders when you are getting a Road Runner as a pet :)

[@UncleDoug]

Despite all the plague-induced isolation, we still have a good time, RR ;) He's very tame. I was talking to a friend in my driveway and the roadrunner strolled right by us. He must patrol our part of the neighborhood.

​@@UncleDoug I'll never forget the first I've seen, in TX then in CA... Took lots of pictures of road runners and their crazy looking eyes.

[@choimdachoim9491]

That was a repair worth a couple thousand dollars. I suddenly realized I'm watching a video of a cat taking a walk, intently watching...was I hypnotized?

[@UncleDoug]

I wish, Choim, but alas, I only charged a fraction of that amount. Glad you liked KC's Big Adventure :)

[@hugomejia593]

Great job uncle Doug and so sad to see Rusty's grave I didn't knew he's passed by so sorry a good friend and company for uncle's Doug

[@UncleDoug]

Thanks for your kind words, Hugo.

[@polkiju7]

Your knowledge and skill are so admirable but holy crap I didn’t expect to enjoy the sound check so much. Beautiful playing. Totally unpretentious and elegant. Great respite from the doom and gloom. Thank you. J

[@UncleDoug]

Wow......so glad you enjoyed the video, P7. Thanks !!!

[@walter4723]

Great Video! I used a Morley Echo/Volume pedal in 1978-1980 then sold it to a pawn shop in Rockville, M.D. Needed cash badly at the time. I could hear the whoosh of the disc in the audio signal quite loud at high amplifier volume. Only went to 330 milliseconds max delay time. Only other choice at the time were an Echoplex or MXR Analog Delay. Still use a Morley Wah/Volume Pedal in my current rig. Thanks Doug, Morley Men Do It With Their Feet!

[@UncleDoug]

Thanks for the nice comments and information, Walter.

[@justinmorrison668]

Thank you so much for making this video! I acquired this pedal five or so years ago, but I didn't have the technical confidence to do a complete restore at the time. I now have mine (almost) fully disassembled thanks to your guidance! Here's hoping I can get that last seized bushing loose. Thanks for the great help and information. :)

[@UncleDoug]

That's great to hear, Justin. Best of luck with your project.

[@randyr.parker2698]

You're a good couple (your wife and yourself) for helping all the little kitties that make their way to your house, we do the same here. We seem to hover around 3 all the time. Seems like when a new one shows up, we lose one of the others from age. Bless both of you! :)

[@UncleDoug]

Thanks so much, Randy. They repay us tenfold for our kindness.

[@reggiewallace260]

Interesting look at some now gone, analog technology. Great restoration. Thanks for the video!

[@UncleDoug]

You're welcome, Reggie. Thanks !!!

[@Byron_Blue]

Fabulous work Uncle Doug! It does deserve to be showcased in a museum. Thank you!

[@UncleDoug]

Thanks so much, Byron :)

[@klauspopp8322]

Great Video Uncle Doug, really amazing ! What a great job, to do all this without drawings and orig. replacements. And how good this pedal sounds ! Thanks to Jack and Oli for the stereo audio test and especially to KC for sight-seeing-tour reg. her sweet home. Thank you all.

[@UncleDoug]

You are very welcome, Klaus. Thanks for joining us.

[@OutlierAudio23]

You just inspired me to dig out and overhaul my Evo! you rock Uncle Doug

[@UncleDoug]

Good to hear, Jon. Good luck with the project.

[@TechTins_Projects]

Interesting that it also gives the frequency of the spinning disc. As you can hear the slight variation in the period of rotation. Great work!

[@UncleDoug]

Thanks, TT.

[@jamesbruno5896]

Well that was pretty amazing Uncle Doug! KC looks happy & healthy! Thanks for sharing & stay safe!

[@UncleDoug]

Thanks, James :)

[@joemcgraw5529]

the smell of the oil im thinking smells like a Elevator Machine room pretty sure the oil is askerel which was a replacement of PCB oil.What a ingenious design!!!! they picked the Best man to renovate this amazing pedal you did a Great job ,enjoyed hearing it as well ,.Thankyou for a Great Saturday extravaganza!!!!

[@UncleDoug]

Thanks so much, Joe.

[@robinosborne266]

Another absolutely brilliant video Uncle Doug. Your attention to detail and the care you take when repairing things is amazing.I have never seen one of these pedals before so it was quite an eye opener for me. Take care everyone and stay safe.

[@UncleDoug]

Thanks so much, Robin.......glad you enjoyed it. You too :)

[@terrycolberg6543]

Great work Uncle Doug. I love the sound of this unit. Listening through headphones on the demo really brings out the beauty of the sound.

[@UncleDoug]

Thanks, Terry. Glad you enjoyed it.

[@CHayden07]

Thinking of you and yours in this winter storm, Uncle Doug! Hope you’re all staying safe and warm. I’m sorry to hear about Rusty (I lost both of my own dogs last year to cancer.) It’s comforting to know he lived out his days with such an awesome loving family ❤️✌️

[@UncleDoug]

Thanks for your very nice comments, Charlie. Being in far West Texas, we have been spared all the misery being suffered by the rest of the state. It was clear and in the 60's today with all utilities fully functional.

[@jamescashin5637]

I got one on Ebay for $50 back in '05. Had some fantastic potential, but also some obvious problems. After watching this wonderfully detailed video, I know for sure that I would've only made things much worse, if I started to dismantle the pedal. I didn't like the looks of the belt/rubber wheel assembly & sadly decided that it was best that I look no further, and pass it on to the next buyer. Hopefully someone has done it justice like you have here. Restorations can be so much more difficult sometimes, than just making something by scratch. Great job Doug!

[@UncleDoug]

Thanks, James. Hopefully, the pedal found a good home ;)

[@thenameless3271]

This was great, thanks UD! Love seeing older pedals like this. The stereo effect is pretty surreal, no doubt moreso in-person.

[@UncleDoug]

Thanks :) With two separate amps, it's a bit more impressive, but if you listen with headphones, it's almost a tie.

[@princepugh7683]

Gosh that sounds very reminiscent of 'Who knows where the time goes' by Sandy Denny! Very nicely brought back to life, Uncle D!

[@UncleDoug]

Thanks, P2 :)

[@abelincoln95]

Unc!! Great job on the EVO-1! You don't see these very often. Thank you for the ride-along! I finally got around to building myself a "current limiter". I even included a small pilot light to indicate/verify when the circuit is live. It's all mounted on a hinged lid box & the 250 watt bulb can be stored inside it. Wish I could share pictures. Thank you for your inspiration and direction!!!

[@UncleDoug]

It was our pleasure, Abe. Thanks for joining us and best of luck with your new CL.

[@billgreen4592]

Wow! Thanks for the trip down memory lane. When I was a teenager, back in the seventies, I purchased a Morley Power Wah Boost. Being an electronics student at the time, I had to open it up and check it out. I discovered the photo-electric circuit and was blown away by the innovative design. That was by far the best volume, boost and wah pedal I have ever had! Everyone told me I should use a Cry-Baby, but I liked this so much more. Sadly, it was lost in one of my numerous moves. Morley was an amazing company and I would love to see them get back in the game! Your restoration was great and it sounds just like the units that I remember from the time.

[@UncleDoug]

Thanks for all your very nice comments, Bill. We're really glad you enjoyed the video.

[@timothygrupp]

That seems to be the exact sound found on the original "Twin Peaks" soundtrack. Very interesting overhaul. Thanks for the invite!

[@UncleDoug]

That's an interesting observation, Tim. Thanks for joining us

[@drrobert2120]

Another excellent video...You're definitely the master when making repairs to these devices. Sounds amazing in stereo! Thanks and KC looks amazing too! 👍👍👍👍

Thanks so much, Doc.

[@centerfoldstands2750]

Fabulous work as usual Uncle Doug! Glad KC is doing so well!

[@UncleDoug]

Thanks so much :)

[@skip1835]

Fascinating - beside the very interesting mechanics of the Morley, I liked the explanation of how they came up with the name (although I wasn't sure if you were "pulling my leg" or not). Anyway, I was captivated start to finish including the chapter about Casey - thanks for posting it UD.

[@UncleDoug]

Glad you enjoyed it, Skip. For once I was being serious.....that's really where they got the name ;)

[@daveogarf]

BEAUTIFUL, Uncle Doug! Very organic sounding.

[@UncleDoug]

Thanks, Dave.

[@Damaraja]

She’s a sweet kitty 🐈‍⬛ And Rusty sure was a hot digitty dawg 🐕 Great work on this wild pedal, Uncle. Amazing that we don’t know how to produce those discs anymore. Seems to be a worthwhile project to decipher and reproduce. Thanks as always for your great vids. You’re the best 🤙

[@UncleDoug]

Thanks so much, D. If there were a huge demand for the discs, I have no doubt that a suitable replacement would be created......but for 10 or 20 customers, it's just not profitable.
