Group buy of EH Bad Stone Phase Shift boards

Information
Scruffie contacted me about arranging a group buy of these boards based on the layout that he, Duckman and Ryan @ Dr. Scientist worked out. I'll be using the same system that was used for the delay add-on boards.
It's based on the (V1) "zombie face" version, and will be 4-layer construction (with internal power and ground planes), with plated through-holes and solder mask. It's sized to fit into a 15900BB, and utilizes board-mounted pots. No OTA's or FET matching in this version, and the board has been updated to include an optional LPB-1 booster at the end to account for the volume drop that's typical in this pedal (whicch works really well, btw).
The photo of the prototype board is here:

and I believe they have shrunk the board a bit since then.
Boards were ordered last night and should be here in about 2 weeks. Order page is up in the meantime for those that want to pre-pay (through Paypal). Boards are $9.75 each + shipping, and yes, I will ship internationally!
Any questions, feel free to PM me or email direct to marcus@digitaldestruct.com

Just to add some notes to Abfackelns post to save issues later...
- Many Builders Report issues when substituting the LM324 Quad Op-Amp so it is suggested you don't.
- The 4009 can easily be exchanged for the more readily available 4049, As Confirmed by B Tremblay (Possibly even the 4069 although this has not been verified yet)
- The Board Features Extra Miniature Pads to add the Manual Pot* found on later Models (Information in the Mod Documents)
*The Manual Pot Mod allows you to switch between Auto Phasing or Manual Phasing so you can use a pot and set the sweep in a fixed position you like or possibly add an expression pedal for something a bit different.
The Prototypes were really nice quality and easy to build up, certainly an interesting addition to the Phaser Family, especially with the added 'Vibrato' Function by flipping the Colour Switch.
Samples of the Original Effect can be heard at these locations -

Got my board earlier in the week - fabulous quality!
I just wanted the one because I wanted to replace my much loved Bad Stone Pedal that was stolen at a gig last year. The board is sitting in from of me at the moment, partially loaded - I'll finish it later....

Here is my build of the bad stone using the board. Worked right off the bat. I used panasonic caps throughout. The booster at the end is not in yet. Hard to desolder the components if you make a mistake, I guess is the double sided plating. Sounds exactly like the clips. Thank you for developing and sharing this nice project.
