Super neat work, tasteful color choices, they look incredibly nice together as a set- thanks for sharing!

Agree - really like the enclosure colors.  Where did you get them - or did you paint them yourself?. NVM.  Missed you saying you painted them.  Nice job!

Agree. They're awesome.

Jon - Great walk-thru, helpful to folks like me who are new and learning.  Thanks very much!

....Start with the power (the ground wire looks like it could use more solder) and go from there. Are you getting good readings from the charge pump pins? Basically go from the power and ground connections and make sure that the circuit is getting voltage. .... That won't help with the LED not lighting, but should be a part of double-checking your work.

Thanks very much.  I did touch up that ground wire after taking that pic, so that's not the issue.  I will follow the power and ground as you suggest.  Thanks again!

You might double check the build doc for the version you picked (the down side of "ultimate tweekability") .  Maybe the power is reversed or there is a NPN PNP mix up.  Does the LED light up?

Thanks. That's where I started, actually, checking power and confirming the configuration. I got a matched pair of PNP transistors from Small Bear. I'm using negative ground with the power inverter.

The LED does not light up.  I double checked the orientation.

Thanks all for the guidance.  I'm lousy at de-soldering, and find it a little frustrating, or else I wouldn't hesitate to replace the cap.  Since it's accessible, I had already decided to keep going with the build, then go back and address the cap if it turned out to be a problem.

Well, I got it all wired and plugged it in and --- nothing.  I've got a long way to go to understand circuits, but based on the schematic (Aion Solaris Fuzz Face) I don't think the cap would lead to there being no sound at all.

I know the 'rock it before you box it' motto, but I've had good luck on the relatively few builds I've done up to this point.  I figured I'd keep building until I needed to make a test rig.  Well, I haven't found anything obviously wrong with the soldering or the wiring, so it appears beginners luck has run out and I'll be shifting gears to work on test fixtures.  I'm going to slog away at it, but might be posting here in a couple weeks looking for help! 

Thanks for the responses guys. The build is for me.

I do have a cap setting on my meter but wasn't sure if it would read correctly when the cap is soldered on the board. I guess I should try it if only for the learning experience.

Here's a pic.

Noob question....
I melted the corner of the housing on a film cap while I was soldering a pot to a board. In situations like this, is there any way to judge if a film cap has been damaged and should be replaced?

Thanks

Love the enclosure designs. What did you use to create the artwork?

Let me clarify, It's almost no volume, you can barely hear it.  Like a broken speaker.

In that case, no. I didn't encounter any issues with this build. Sorry I can't be of help.

I built one a few months ago and will try it today and let you know. Are you using single coil or humbuckers? (Not sure if it matters, but I'll use what you have)

Just for fun (I'll really try to stop wasting everyone's bandwidth with my nonsense after this, I swear  ), I gave the first 30 project names from the MBP store to an artificial neural network and asked it to extrapolate.  Here are some AI-generated MBP pedal names:

Brilliant...just brilliant!

Plus, here is Mammoth red (left) vs. Smallbear "red" (right):

Love the engineering paper pad.  That stuff is the best!

Great stuff, thanks for sharing this. Sounds great!

PPP has minimum buys now.  There's another thread in this forum called Mammoth Electronics acquisition that covers related topics
