I'm not really interested in reverse engineering this pedal or posting pics that will allow others to do it...BUT...i was VERY impressed with the construction quality for this pedal. Dave Barber continues to set the standard just a *bit* higher...

Never seen a layout so much lacking of wires.... just half an inch of bare wire whereever possible. The pots and jacks can be considered as almost-PCB-mount. Great job.
Never heard of the Barber guy though. Should I be?

yep...he makes GREAT sounding pedals. also, some cool "tweaks" and mods can be found on his site that apply not only to *his* pedals, but to many other pedals as well. (stacked opamps, bass tweaks, etc)
He stops in here occasionally.

THAT is totally admirable!
i love the fact that there arent very many wires going on...nice and clean.
actually, i kicked my barber burn unit off the board cause i didnt care for it...
a month later, its right back on, after i tweaked the internal EQ (OFF) and turned the DYNAMICS all the way down...HEAVEN! :D
He builds some nice stuff but, I have never cared for any of his pedals.....don't know why just not for me I guess.
I'll check out the guy's webpage.
Ahh yes, dragonfly, I'm still expecting a full version of your avatar pic in my mailbox, you said you had it. ;D

PM me your email address, and i'll email it to you...i have hundreds of pinup girl pics...elvgrens, rolfs, vargas, etc, etc...

If there is one thing there is no shortage of on the web is classic pinup pics.
Although I do have to admit, as big a fan of the classics that I am and I know you are Dragonfly, that these modern graphic pinups are devilishly tempting.

Oh right then, about building pedals...
I love to see that pseudo-PCB mount trick. And so well thought out too.
I though of using it myself to make pseudo PCB mounted pots.
Just layout the pads for the pots in the general area below the panel mount pot and use bits of resistor cut-offs to connect the pot lugs to the pads.
I wanted to do this on soggybag's universal layout that includes the PCB mounted jacks and switch.
This is a new twist for me.
By using the larger BB box and locating the pad NEXT to the part instead of below it really makes for a harmoniously clean build.
This is a real clever manufacturing concept that is within the realm of any DIY'er.
Anybody designing layouts could design for this off-board technique.
The best part is we can do this without buying any new parts, tools, or consumables.
Cheap effective use of what I have already.
Thanks for posting this Dragonfly!! :icon_biggrin:
My build technique will evolve.
Barber sure did a nice job. The old style on the fiber eyelet board was way cool too!

I've got a bunch of theirs as well !

He really does fantastic work !
Well done!
The shorter the wires the better the construction!

OMG, that pic has a GREAT (great as in cheap, easy, quick) way to hold the battery in place!
Bent sheet metal held in place by the footswitch. Why didn't I think of that? Oh because I don't use batteries :icon_redface:
But if I did I would start mounting them this way. Brilliant, thank Dan N! :icon_smile:
Some of this guys marketing belongs in the Voodoo thread:
Quote# Vintage style components - Carbon comp resistors, metalized polyester and silver mica caps, vintage vibe throughout.
# Vintage style brown barrel knobs - These knobs have a sure grip while dialing in sweet tones.
# Vintage blonde textured powder coat - Very durable and VERY easy on the eyes.
# Varying asymmetric drive - Higher drive settings and harder playing gives you more asymmetric clipping, back off and the overdrive gets more symmetrical and clearer...like a cool old tube amp!

that's is pretty nifty! i'd be more interested on extending it to support the sides (top and bottom really) of the battery since you can wedge it between the switch and the enclosure but you can't always stop it from sliding around.
When the gap between the sheet metal and the box is setup right the sheet metal clamps the battery and prevent any sliding.
Somewhere on the web I've seen U-formed 9V-battery clamps made of Si-steel (spring steel) that can be and mounted by a screw.
The new Menatone pedals have a slide in battery box, I think this is also a good solution to prevent any battery sliding.

I've been using
these (http://www.radioshack.com/product/index.jsp?productId=2062220&cp=&pg=2&origkw=battery+clip&kw=battery+clip&parentPage=search) from Radio Shack and they work great. A little epoxy on the bottom holds it in place just fine.
The idea with the epoxy is great. :icon_biggrin:
Does somebody know what type of caps are the grenies in Dan's G-pic? (manufaturer, type, value)
The yellow is a Mallory 150.

I have a couple of friends who got a Barber Burn Unit. They really liked the pedal. I don't have any personal experience with them, though.

I don't know the brand. Clark was using tube amp parts, so my guess would be 400 to 600 volt film caps. The value was 0.1uf.
Are those carbon composition resistors in the pix?

carbon comp as they get (: i can't even find those kind in australia, not that i want them!
Rs are CC from Allen Bradley. Interesting that the 22k is always 2W.

I know this is an old thread, but I was trying to find the original layout, point to point tag board style. so far I can only find the Vero version. If anyone could point me in the right direction I'd be greatly appreciative:)
There are three versions. They are very similar, slightly different voicings.
I reversed two of these back in 2003 and Jack Orman did the third one.
Without going through the small details it's a Boss OD1 circuit with a few tweaks:
- 1st stage; 4k7 to vdd/s is replaced with a 25k pot + series 1k;
one version has 100n caps instead of 47n
- the second stage has a gain of 2 not 1
- the second stage filter cut-off is pushed up to 3.3kHz or 6.6kHz depending on the version
- after the second stage is a slight amount of high pass filtering on the level control.
The Timmy is another spin on the same theme.
