The etch is perfect and these knobs are AWESOME  :o   Where did you found'em?

Thanks! I get the vintage stuff off e-bay.

Ok, I admit it. I'm a sucker for Tremolo, Vibe and Rotary effects.

This is the ROG "Tri-Vibe" built using a board etched and populated by Stephen on the BYOC forum.
Felt funny using a board populated by another builder but the price was right and I wanted to try it.

Sooooooo, here it is. Art Deco inspired design, acid etched top design, vintage knobs and a pulsating led.

How's it sound? Sometimes I love it, sometimes I don't. It can be noisy with some pedals. Like many of these effects it has a volume drop ( much better after I replaced a chip that was not the recommended one).
I use a transparent buffer as a boost. All in all, some very cool sounds when you get it dialed in.

Looking forward to building the "QuadroVibe" when the boards are available from MB.

Looks like a Vegas Slot all it's missing is the One Armed Bandit pull lever on the side.

Kinda reminded me of a playing card :o Vegas works for me!!!

a work of art as usual!
kinda noir, kinda western, kinda psychedelic

I'm a sixties kid so that makes perfect sense! Thanks everyone for the kind words on this one.
All I can say is this forum has been inspirational and thanks to Brian for the amazing projects
and info at Madbeans.

Thanks everyone for the the good words on this build.  :D

Dude that's a sweet build. I love the etched enclosure! Did you use a particular layout or just make one?

I design the enclosures using photoshop. I love vintage knobs and buy them off Ebay. The designs often develop around the knobs I've selected. The swirl pattern on this pedal is stock vector art from The type face is "Rat Fink" a free font off the web. I usually start with the basic layout for the hardware then the labels and name of the pedal. Then I see what kind of pattern works to unify the overall look. I looked at 10 -12 patterns before selecting this one. The background pattern has been heavily modified in photoshop. Takes me longer to design the enclosure than to build the pedal!!!!!!!! :o

Straight ahead  Germanium Fuzz Face on vero with a couple of mods. Bias trimmer, added a pre-gain pot and a power switch. I hate having to unplug my battery operated fuzz pedals  ;D

Transistors are GT308's from Musikding in Germany. They sell lots of different types of GE trans all sorted by gain. Very reasonable prices. I got a variety of types to experiment with. These two are 70-80 and 80-90. Has a surprising amount of gain and it's freakin loud! Lots of great, great tones and range especially with the pre-gain. Cleans up very well and plays well with my other pedals too.

I socketed the output cap and tried several different types with the same rating. They all sounded different to my ears. For this pair I settled on a Wima box cap. Somewhat more harmonics and sustain.

Used an axial cap (I forgot to order a radial) and had to tip it to shut the bottom.

The enclosure is etched using PNP for the mask. The knobs are vintage. Sanded the blue led to diffuse it.

This is my favorite Fuzz so far!

+1 on the Tayda 22awg solid core. I've used most of the others mentioned here but I really like solid core the best. Stays where you put it, fits into sockets and stays there, easy to strip and solder. Takes a lot less fussing over and it's cheap from Tayda.

Great work, inside and out. Really Beautiful!

Fantastic build! Love the retro look and super clean all around. Where did you source the enclosure and did you have any issues drilling the steel?

There isn't much information on the website, so I was wondering if you guys can help:

Do you end up with some kind of certification at the end of it (I assume you would have to pay if you did)?

Is the course open to US citizens only?

Are there assignments, projects etc. that have to be completed to continue the course?

Any info would be most appreciated.

As far as I can tell this is open worldwide. Some of the online courses from these top schools (Stanford) offer a certificate without the schools name on it. Check out the NYT's article.

Hey all, The New York Times had an article today about Universities offering online courses for free and I found this one offered by MIT.

Here's a description: "6.002x (Circuits and Electronics) is an experimental on-line adaptation of MITís first undergraduate analog design course: 6.002. This course will run, free of charge, for students worldwide from March 5, 2012 through June 8, 2012."

Here's a link to the page to sign up.

I thought some of the forum members might be interested in checking this out. It is an intro class to circuits. And it's FREE  :o

Love this!! Very, Very cool inside and out. Inspiring! :o

Great! That's what I needed. ;D Thanks!!


For external control, get a 16mm Alpha B500R pot, and wire one pad for the resistor to the middle lug (lug 2). Then wire the other pad to lug 3, the right side lug if the lugs are towards you and the shaft is pointing up.


Thanks for the quick response. It's an external control. I want to be able to go both below and above the 470R value to adjust the gain on a transistor. Will the B500R allow for that or would I need a B1K?
