Another Easy Fix for a Morley Pedal

I recently acquired a 1970s Morley MVO Wah Volume on eBay. It was listed as not working/for parts, so I got a good deal on it. Here is a picture of the pedal as it was when I bought it:

And here is a picture of the pedal as it was when I sold it:

There are three issues a non-working pedal can have, and the Morley WVO had two:

• Mechanical: the treadle was loose and laid all the way forward. It moved freely like a treadle should, but flopped forward as soon as I took my foot off it. Also, the tolex flap inside the pedal that blocks the light came unstuck from the tape that holds it in place (see a brief description of how this works in my previous post at http://momentfx.blogspot.com/2014/03/simple-fix-for-1976-morley-pro-flanger.html).
• Cosmetic (which is really only an issue if the plan is to resell the pedal, which I did): The chrome was decidedly dull and the treadle pad was dirty.
• (The third issue is electrical, and this pedal had absolutely no problems in that respect.)

The first mechanical fix was the pedal, which was easy. I used a 5/16” wrench for the bolt and a 3/8” wrench for the nut and gave each a few slow turns. A plastic bushing maintains the friction required to hold the pedal in position. If you were to overtighten and crack the bushing, they are not specialty parts, so you could get one from any hardware store. Nonetheless, you should only tighten a little at a time and check for feel after a couple of slow turns.

The other mechanical fix was a little trickier, and I didn’t notice it until after making arrangements for a potential buyer to come look at it. The flap that blocks the light is made of tolex (fake leather made of vinyl and fabric), which had become stiff over the last thirty-some years. So rocking the treadle back and forth must have worked it loose from the tape that was holding it in place.

Because of the age of the pedal, I did not want to replace anything, even a piece of tape. So I took a length of double-sided tape and placed it along the edge of the tolex. I put it in place and pressed the original tape down on the tolex and it held. I was thus able to keep all of the original components of the pedal and the fix is invisible. I know it’s only a piece of tape, but I wasn’t sure at the time if the buyer was an avid collector or just someone who wanted the pedal for nostalgic reasons.

The cosmetic fix did not require any troubleshooting, but it did require some work. I used window cleaner for the chrome and a damp cloth over a screwdriver tip to clean every ridge in the treadle pad. After about a half hour, the pedal looked almost like new. Well, not new, but an old pedal that has been well taken care of.

I was able to resell this pedal on craigslist very quickly for a tidy profit. I probably could have gotten a bit more on eBay, but not having to pay fees or pack and ship the pedal was worth it. A bird in hand . . .

A few takeaways from this one:

• Take the time to clean whatever your selling.
• If the item only requires a few turns of a wrench to get it in working order, it’s worth the effort (and possibly the price of a wrench).
• When selling a pedal, always give it a quick test before the seller comes. If I hadn’t, it would have been pretty awkward. He did not want to test it, so he would have gotten home, found out it didn’t work, and I would have looked foolish, if not dishonest.

Univox Super Fuzz Clone

One of my friends asked if I could build a Univox Super Fuzz clone using enclosure he liked. I used the vero layout on Guitar FX Layouts blog at http://tagboardeffects.blogspot.com/2012/01/univox-super-fuzz.html.

Here's the completed enclosure (I had nothing to do with the design—not sure what the story is on that):

To preserve a bit of vintage feel, I did not include an LED or a DC jack on the pedal. When I thought I was finally done, my friend asked if I could put a jack in, so that was the final step.

I had already mounted the board to the closure with mounting tape, so rather than remove that and risk cracking the board or scratching the paint or the like, I decided to install the jack with everything else in place. 

To drill the hole without getting metal bits all over the inside of the pedal, I stuffed a shirt inside the enclosure. When I was done with the shirt, I hung it back up in my wife's closet, in case she planned on wearing it to work the next day : )

I snipped the positive battery wire, leaving a little wire on the terminal:

I then rerouted the long end of that wire to the DC jack. This wire now supplies the 9V+ to the board from the jack instead of the battery. 

Quick explanation: For those who don't know, the battery is connected to one of two positive terminals on the DC jack. The other positive terminal supplies power to the board. When using a battery for power, these two terminals are connected, so the power comes from the battery, through the two terminals and to the board. When a DC power supply is inserted into the jack, these two terminals are disconnected. So even if the battery is plugged in, it no longer is connected to the board in any way. The power comes straight from the power supply to the board.

I then spliced a wire onto the short positive wire on the battery terminal and ran that to the jack. After grounding the jack, I was done:

And here is a quick and sloppy demo of Sasquatch playing through the Super Fuzz (I'm not sure what my camera was focused on, but it's nothing I can see). The Balance and Expander knobs are at about 7 or 8. Half way through, I flick the Tone switch. My dinky camera mic captures the difference, but not faithfully.
