Unnecessary Backstory: The Stompbox-Making Phase of Sean's Life


Some months ago, I convinced myself that What I Needed was a TubeScreamer pedal to run though my distortion-less tube amplifier. Lara helped me convince myself to make a clone, rather than buy one. Imagine if every art student had to make their own version of the Mona Lisa. The original TubeScreamer came out in the 70s, and since then, just about every stompbox artisan has made their own version of it. Circuits and even cheap boards are all over the internet - I used a board bought at tonepad.com, made by a stompbox artisan named Francisco Pena. I made the pedal, it worked great, my wiring was embarrassing but my solder joints held, and Lara made a killer design for it.

I'd started stalking around the DIY Stompboxes Forum. I dug out the ol' breadboard. I even sucked it up and bought some electrical bits and pieces at RadioShack. I eventually learned to read simple schematics and slowly transfer them into cluttered but functional reality. I was officially In A Phase.

But electricity is hard (for me) to understand, especially once you get beyond connecting powerstrips together. I tip my hat to those who truly understand things like impedance and the effect a transistor has on signals going in all kinds of directions. I'd expected/hoped that circuits would be like a diagram of how water flows through a series of pipes, but no luck. I was faced with a steep learning curve, and unable to completely figure out how things like tremolos and delay pedals worked, I stuck to what are generally the simplest projects: distortions.

Like seemingly everyone who delves into this hobby, I made and loved a Bazz Fuss (sorry for the Google link, but I think it illustrates the point). But honestly, how many distortion pedals does one non-guitar-tone-god need? There seemed little point in taking my perfboard bazz fuss and adding conveniences like a switch and a case. Until...


THE FUZZY BEAR!


I stumbled upon an idea so gimmicky that it could not fail to make me rich: a fuzz pedal, in a teddy bear, called The Fuzzy Bear. Next on the list, incidentally, is a compressor called Huggy Bear. In my fever dreams of filthy lucre, this series of stuffed animal effects pedals come with small male-male 1/4" adapters, so that when you chain them together they look like they're all holding hands. Eh? Who would not buy them?!

Lara and I found the perfect bears at Walgreen's, which - as I had suspected - had marked down many a stuffed bear after Feb 14th. We bought this set of two, where when they touched noses (okay, "kissed"), one of them would emit a digitized kissing sound and start flapping its motorized cupid wings. I'm really sorry I didn't make a video of this, or even take any pictures of the pre-disassembly bears. For something like $5, I got two good-sized teddy bears, one of which already even had a battery pouch and a space for a box of electronics! The photos explain the construction pretty well, I think, so I'll leave it at that.

You can also hear fuzzy used on the song Make It True Or Crush, by The Parents. The guitar line that comes in before the last chorus is Fuzzy Bear'd.

Potential Improvements


If someone were to try to do this The Right Way, here are a few things they'd do differently. First, they'd use a more robust circuit (i.e. not the wonderfully-quirky, unbuffered, perfect beginner's project Bazz Fuss). Second, they'd either use sealed jacks or perhaps use some heat-shrink to seal the standard switchcraft-style jacks. Yes, I've actually had to jam a stick in the jacks to push the cotton out of the way. Third, they'd want to figure out some shielding. It hasn't buzzed all that badly for me, but since the pots and the jacks are basically just dangling on unshielded wires, it'll certainly get hummy in certain situations.

As for why these aren't at Guitar Center yet, or even on Etsy or somesuch, I just kind lost interest. I love ol' Fuzzy dearly, but he's pretty finicky: he buzzes, sometimes he's oddly silent, and this despite my being very gentle with him. And though I should probably just make an etchable layout of the circuit, my layout skills are nil, and I didn't relish the thought of making more crude perfboard monstrosities to reproduce a flaky pedal. But if you, dear reader, are good at this kind of hustle, and want to help me live in a solid gold house, let me know!


Addendum:
I just reread this, and was shocked to find that this tasking is nearly a year old! I held off partly because I kept forgetting to make a demo video at neighbor-friendly hours, partly because I kept meaning to make a nice-looking schematic, and partly because I've just had some trouble finishing things lately (perfect vs. good, neurochemical imbalances, etc). In the back (well, maybe the middle) of my mind, I also thought I should get my act together in terms of somehow trying to sell this idea — y'know, making them myself, pitching some company to make them, or some other such scheme I'm not really cut out to realize. But even warm fuzzy open source Make Magazine -style capitalism is hard, and it's time to be doing! Ergo, "posted".

A 3PDT switch is probably overkill for this guy, but...

Dear Mr. Mahan,

I want to start a band named "Stomp the Bear" in honor of your twisted creation. Also, I have a friend who will want this for his band.

Love,
Inky

Particularly awesome. Is the Huggy Bear out yet?
