Group buy of EH Bad Stone Phase Shift boards

Duckman · Post by **Duckman** » 15 Nov 2010, 20:25

I noticed in the BOM that a 1.5uf Tantalum cap is specified for C13, but the cleaned up schematic shows 1uf. The other schematic, http://topopiccione.atspace.com/pjimage ... ne.sch.gif shows 1.5uf as well so I suppose that is going to be the correct value. Anyone know?

I first used 1uF+0.47uF in parallel, but didn't like the way it looks, so then did a little test on a breadboard, switching the paralleled caps with a single 1uF, without any noticeable change (at least on sound)

I found a 10 pack of 1.5uf Axial Tatalums on ebay for a buck + shipping. Will have extras leftover along with the LM IC's I mentioned earlier. Getting started this weekend! The board looks killer BTW! Very nice quality, very robust.

^Thanks for the nod. Got my pcb today, did anyone else have to pay the post office to get theirs? Either way this pcb is damn sexy! Thanks for putting this together

Shouldn't have to pay the PO to get your boards.... Are you outside of the US?

Im in Hawaii, not sure if it matters? I blame usps

It was only 34 cents for the postage due thou so there's no worry.

Again. A great PCB! Easy soldering, nice compact layout. Are you going to get more of these once your supply is exhausted? I am going to send this pedal around to some of my good repeat customers and I expect quite a few will want one. Thanks!

it's about the exact width, and there's just enough room the switch. I think it can be done! I'm going to see if I can wire it up today after class.

Did you find out if it would cram into a 125B or not?

I certainly hope so....
Otherwise...

This could get very awkward.

Oh I am liking that

Can we expect our first demo from you...? It looks like the sorta pedal you'd see demo'd on youtube

hey guys,
i really like the idea of this group effort thing!
is there another group project planned?

Glad you enjoyed it

Maybe, if there's enough time, money and interest and the other parties concerned agree... we'll just have to wait and see

This one is still open though

Not for much longer.....only about 20 boards left now.

hey abfackeln,

i have received my board a couple days ago! Good stuff! Don't when i will be able to build the pedal, though.

how many boards did you get made in total?

Ordered about 100.... less than 20 left now.

Thanks for putting this together. Getting ready to buy parts for this and a bunch of other pcb's. This is my first time sourcing parts for entire projects, up until now it has been all kits and mods. The parts list did not have pf/uf next to the caps. When I look at the schematic all the caps have uf, so I am assuming all the cap values are expressed in uf. I just wanted to double check before ordering because I need to buy a bunch of 470pf's and this is the only board that call for a 470uf.

Thanks

Yup they're all in uF, so 0.047 is 47nF and 470 is 470uF.
Good luck with the build!

Thanks Scruffie!

Just did some checking and this will fit in a 125B, but only if you turn the board sideways and don't board mount the pots.

Post by **azrael** » 29 Dec 2010, 02:31

Yeah, that's what I'm doing. Got sidetracked with some other builds but I'm finishing it up now. Does a non true bypass LPB affects the tone of the circuit any?

Don't know of anyone that's tried it yet! If the pedal is true bypass it wont affect the overall tone but it might add some colour to the Bad Stone, don't really know!
