Build Reports / Re: Clone Theory in a 1590B

Those 680pF caps should be 412pF by the way, Tagboard used an outdated schematic of mine, parallel a 390pF & 22pF.
Good to know, and a simple fix.  Thanks!

I'll have to issue a recall of my first build.   ;)

I've been working on building a second one of these.  This time, I've squeezed the jacks a little more toward the switches, so I had to modify the boards less.

I've widened the charge pump board slightly to make it lower in profile.  On the main board, the red cap at top center is the same as the one mounted to the back of the board in my first build. I've slid the top lead down a row here to increase jack clearance, but now it is on the correct side of the board.  Other than that, the only real changes from the tagboardeffects layout are the corner cutaways and the shifting of the large electrolytic caps to allow them to lay on their sides (the large 1uF film caps are also moved so they can lay on their sides, but their leads still go to same holes as before).  The +15V and ground connections to the main board will still be made directly to the leads of the large cap, as in my previous build.

I'll need to adjust my graphics to match the slight shift in jack positions.

Enclosure on the site is from PPP - a brushed finish with Emerald Green Transparent, if I remember right. I just added my artwork PDF to the Blueshift project page, so you should be able to send that to them and get the same thing.

awesome thanks!
+1 Thanks!

Kevin could describe these pro line circuits as, "Does nothing more than emit sporadic fart noises along with an ear-piercing high pitched wail," and I'd still want to buy the boards and build them -- they're that beautiful!
#1475
Could you say a bit about the finish?  Was an artwork file posted?  I couldn't find one....
Your pedal has a frosted look to it that is kind of interesting.

Is there a Vero layout for the pitch pirate deluxe floating somewhere out there that I haven't seen, or is this an original layout?

Check out this info on Royal Blood's setup.  It's just two guys: a drummer and a bassist.  8) Hopefully, you find this relevant.

Thanks again, everyone!

Believe it or not, I'm actually thinking about making another one of these.  As I mentioned before, this one is going to my friend, but it does sound pretty good, and I don't currently have a chorus pedal of my own. 

If I do end up building another, I'll try to document the process more, including providing an updated Vero layout with the necessary changes to squeeze this in (along with any component size measurements where it might make a difference (electrolytic caps, mainly, I'd imagine).  I'll make a drill template too (already have that for everything but the jacks from when I made the label).

Don't expect it too soon though....

Also in the works, I'll record a video demo of this (after I figure out how best to do that).

Tagboardeffects:  You probably can't do this.

Exactly!  ;D
That does capture it quite well.

He's mad!

That's very impressive. I think the original Clone Theory graphics are some of the best on a pedal, and great job on those as well.
Thanks!  I'm happy with how the graphics turned out as well. But, thanks to the hard work and generosity of others I've already mentioned, I mainly just had to scale and move stuff.  I am pretty proud of changing an upside-down 'G' into a '9' though.  ;D

Thanks, everyone!

To be honest, I didn't know if this would fit before I started building it. 

Here's a bit more info, for those interested.

I drilled out the enclosure, setting the pots as high as I could (no pun intended) and the switches and jacks as low as I could (almost, anyway -- you can probably see that I could have slid the input/output jacks a tiny bit lower).  I figured I could always put something else in this enclosure if the Clone Theory didn't fit. 

Once I got the two boards mostly populated, I started checking the fit to see which way I would have to orient the main board (determined mainly by the position of that large 470uF cap) and what parts would have to be moved. That cap soldered to the back of the board was interfering with the plugs going into the jacks, for instance. 

I also knew from past builds that there is plenty of aluminum that can be carved out of these boxes to give a bit more room, if needed.  Because that board takes up the whole width and is solder-side-up, I filed off the lap joint flange on the lid along about 75% of the length of the box.

I assumed that if the boards fit comfortably then the wires would too. Once I could get both boards in and still have them rattle around with the lid on, I was fairly confident it would fit.  It was at that point that I worked on the graphics.

Thanks!
I probably wouldn't have attempted this if it weren't for this line on the tagboardeffects site: "It will fit in a 1590B if you want the aggravation, but a 125B would probably be a better choice." Being in a spiteful mood, of course I accepted that challenge.

Build Reports / Clone Theory in a 1590B

I also posted this on DIYSB, but wanted to share it here as well (got some great help from some people here).

This is the Clone Theory in a 1590B that I built for a friend who owns a vintage 70s one.  I was disgusted by how much pedal board space was wasted by that one giant pedal, so I told him I could probably make him one much smaller.






It's based mostly on this layout:
http://tagboardeffects.blogspot.com/2014/05/electro-harmonix-clone-theory.html?m=1
But, I had to move a bunch of stuff around to make it all fit, and I had to substitute some parallel combinations of resistors and caps to make up for shortcomings of my inventory.  Also had to file down portions of the lid and jacks.  I'm happy to report that it works after all that.   ;D
It was a very tight squeeze, and I fully expected something to short out disastrously upon closing it up (not shown in the pics is the gaffers tape I added as insulation on the boards and pots), but it worked perfectly when I powered it up.   

Special thanks to Antoy, juansolo, and Kartoffelkopf for sharing graphics from their Clone Theory builds with me.  8)

And, of course, thanks to IvIark at tagboardeffects for doing the heavy lifting on the Vero layout!
