I play for the worship team at Southeast Christian Church here in Louisville as well as another group called 4th Watch.

I went to a missions conference at Southeat a few years ago. That is a BIG church. Must be great to play on that worship team.

Hi. I have enjoyed reading these posts.

I am trained as a clinical pharmacist. I went back to college in my late 20's when I realized I wasn't going to be a rock star. After graduating and some post-doc training, I worked as an Assistant Professor at a pharmacy college. About 5 years ago, I was lured to the "dark side." I now work for a biotech pharmaceutical company as a Regional Medical Liaison. I travel around and talk to docs, give educational presentations, and support clinical trial sites. It's great because I work from home often. When I'm on the road I get to visit lots of music stores and hunt for used pedals to mod.

That's what I do. Thanks!

I put electrical tape on a business card and then cut it to fit and slide it in between the pcb and the pots. Those business cards aren't good for much else...

Nice work - they both look great. What opamp did you use in the serendipity? Looks like a BB.

Speaking of... iPhone formated forum could be cool...

The "Madbean App" would be awesome! +1

Hi, I think I may be able to help. I often leave off the 9V battery snap.

Check out this wiring diagram: http://www.madbeanpedals.com/forum/index.php?action=dlattach;topic=707.0;attach=214;image

The black wire is the neg- lead from the 9V battery going to ground on the Ring of the stereo input jack. But the Brown wire is also grounded on the sleeve of that jack. When you plug in a mono guitar 1/4" plug you connect the ring to the sleeve and the battery lead (ring) is connected to ground (sleeve). When you pull the plug - the battery is "ungrounded" and that saves battery life.

So if you leave off the battery snap your power source and circuit are still graounded to the sleeve of the jack via the brown wires shown.

Does that help?

That is really nice. I am going to print your guts shot and put it up over my work bench for inspiration.

I really like Irish look of it. For a second I thought there was a pint of Guiness in the background of your guts shot.

Thanks for posting!

Are you using a mono jack in the input? I've always used a stereo but I don't know if it matters?

Yes, I just used a mono jack since I didn't bother adding a battery snap. The stereo jack is only helpful in preserving battery life, and then only if you pull the plug out of the jack. I never use batteries anyway.

As an aside, I attached a 2.1mm plug to a 9V battery snap that I use for testing. That way I can plug the battery into the DC jack and don't have to undo any screws.

And on the board (next to my Yellow Shark!).

Here is the gut shot.

This is my first time posting a build report. I am really happy with the way this turned out. I used a 1290NS enclosure from Pedal Parts Plus - they painted it "Purple Starlight." I drilled it and used the small Boss-like knobs from the Shack (have you noticed they now call themselves "the Shack"?). I don't usually like those knobs but they work on this one.

I put a strip of red electrical tape under the jacks because I drilled the holes a little too close to the top of the enclosure and the tip contacts were touching the enclosure.

Anyway - the pedal sounds great. My new favorite.

It's impossible to pick one. I voted for Yellow Shark, but Serendipity and Neutrino are awesome too.

That is a great idea. Can you show us a shot of it in action? I'd like to see how you power the circuit.

That is really cool. Nice job!!

I agree that its a great circuit. I built one on strip board with a layout from FSB. Real easy build and classic sound.
