Title: Demo Tape Fuzz
Post by: Stomptown on August 16, 2017, 04:23:16 AM
Recently I've been devoting most my personal time to building an amplifier so this is the first pedal I've finished for myself in a while.  It's a Demo Tape Fuzz based on Brian's schematic in the etchers paradise section and it sounds awesome.  Designing for the Bare Box took a bit of extra effort but the build went surprisingly well.  I used Cricut inkjet vinyl sticker paper for the graphic and envirotex for the finish.  The jumpers are a borrowed idea from Leevibe's Phase 45 build (thanks Lee).  The graphic is based off a BASF poster I found on the web, which for copyright reasons I'm guessing used "BASE" in the logo.  Somehow I didn't catch it (face palm) so I guess I unintentionally avoided copyright infringement.  ;D

If anyone for some reason is interested in building one of these, i have the leftover PCBs for sale here:

A "Low Noise" and "High Output" fuzz, eh? :) I remember boxes of BASF brand cassette tapes in Dad's old hi-fi cabinet.

Verra nicely done. Smallbear Bear Box?

that's a preposterously classy build, amazing job.

i made the scumbag garage version on vero a few weeks ago, a lot of fun, really cool sounding and quite versatile pedal

Yeah, it's a Bear Box.  It took about 2 years to find the motivation to design something to fit in there.

Spectacular. Top notch in every respect. Those are like the orthopedic shoe of knobs and you even managed to make them look perfect.

Very nice build, per usual. The graphic is pretty cool, but those jumpers....Ahhhhhhhhhhh.

I'll call it now: Build of the year 2017!

Top notch work in every aspect starting from the graphics and exterior execution to the perfect board layout and those sick jumpers!

on a side note: do you think one could manage to put in top mounted jacks with 2 pots?

Fantastic Job! I know what you mean about the bare box too. I have two of them and I have absolutely no ambition to use them. Great design.

I remember the BASF brand floppy disks I used with my Commodore 64 as a kid.

It's might work with 9mm pots and lumber jacks but I'm not totally sure.  There's not a whole lot of room up there!

CJ, did you cut notches in them, so you could use the other side too? :)

That is a really impressive build.

Is that some kind of epoxy or glaze you used to coat the artwork like a Parks super glaze or envirotex?

Yep.  It's envirotex.  Pretty easy to work with after a bit of trial and error.

I have high arches! I need the extra support when turning knobs with my toes!

Seriously, though; that is a spectacular build. Graphics are understated and elegant. Guts are super clean.

So very sweet, both graphics and build.

I can't get over how beautifully symmetric the jumpers are. Did you have jigs for bending and assembly? If I tried to do that, they would each be bent differently, get crooked when soldering in, and have scratches/pliers marks from the shaping.

I basically stretched a long piece of bus wire, cut it into pieces, bent them across the thin side of a board, and inserted them one by one.  Finding a board of the right thickness was the key.  Other than that it was pretty easy.

You're more patient than me -- I would have just stuffed a load of zero-ohm resistors in there!
