General Questions / LED question - Horizon
« on: July 12, 2021, 07:21:38 AM »
I guess if you build enough pedals you run into firsts. So I built up the Horizon, amazing pedal love it, and used it for a few months. Then one day the LED doesn't come on. The pedal still works. I think no biggie, bum LED so I swap it out. Nothing. So I figure let me pull it off board and wire directly to jack. No go but here is my question.

Can I ground the LED to any ground point? I thought I could. Typically I don't use 4PDT boards and wire the LED's with the ground attached to the 3PDT. But since this build uses the 3PDT board I can't do that. So, I just wired it to my main ground point at the input jack with the 9v anode directly to the DC jack like normal.

Anyone have any troubleshooting thoughts? Did any of this make sense?  :)

So, I just finished testing this one and it is working but I have quite the wonky voltage reading. I'm thinking it might sound better, or how it was designed, if I can figure out why this weird voltage reading. All other readings are on par. Anyone have any thoughts?

C = -.68
B = 121.4   :o
E = 0

C = -4.38
B = -.68
E = -.55

Anyone have a good source for this? Is there an equivalent for this build?

So I have been working on my quarantine family and basically building 10 pedals at the same time. First 8 fire right up. Then I get to my 2 Blueshifts. Both are completely dead. Not a single sound so it would appear I have fundamentally done the same thing wrong, maybe. Built one with stock bypass and one with minimal bypass.

Two quick questions.

1. Is there a mechanical connection between the boards? By that I mean I dont have the boards connected by header pins. Ive used a different larger enclosure and have laid them flat.

2. How is the larger board grounded and how does it get voltage? The small board gets grounded and has the 9v connection.

Well, my trusted source, Papillo, has discontinued them for us small fries. So, I'm on the hunt. Who do yo guys use? You like? Dislike.

I know not all water slide decals are made the same. Papillo's were killer as I never had an issue with them. Some others are not so good.

So this BOM shows 2.2uf FILM caps for 3 spots. I've never seen anything larger than a 1uf film cap in pedal projects so needless to say I don't have the 2.2uf film ones.

Can I still use a 2.2uf electro in it's place? If so, what are some possible differences?

I don't have any more ordres to make so paying $8 for shipping for 3 caps from Mouser is something I'd like to avoid  guess.

1. Is there a work alike transistor for the BS250p? Literally the only thing I need is that and just ordering that from Mouser will be an expensive transistor.
2. How important is the 1/4 ratings on those 5 resistors? I do have some 1/4 watt stuff but not those values.

So, I'm going to build a compressor called the Constrictor from PedalPCB. It calls for a VTL5C10 but I can't locate anywhere. I can however find the VTL5C9. Is it a good swap.

Below is the data sheet description. As it relates to how the compressor would act I have no idea if the '9' is swap worthy for the '10'. Anyone else have a thought or ten?

VTL5C9 has a 112 db dynamic range, fast response time, high dark resistance, but with a more shallow slope and lower on
resistance at low (1 mA) drive currents than the VTL5C1. VTL510 offers a low on resistance at low drive currents, a fast response
time, and has a smaller temperature coefficient than the VTL5C9.

Open Discussion / Acoustic guitar string question
« on: October 10, 2019, 07:31:01 AM »
So I have a relatively new mahogany Martin and it is just a tad dark sounding for my tastes. When I plug in of course I can adjust and it sounds great. But unplugged I need more chime for what I like to hear.

Is there such a thing as some strings being more chimey than others? What strings might you guys suggest in this situation?

Ok, so I've built Bean's MXR117 SAD 1024 version. It's up and running and sounds great except for the noise. While I can live with a little noise there is just too much to make this pedal usable. I'm out of my element on how to reduce it to where it's tolerable. I've tried it on a One Spot as well as my Voodoo Lab's PS and it is the exact same. It is not in a chain of pedals.

Noise wise, you hear the clock but if that was all I heard it is low enough to where I could get by and not sweat it too much. But the classic swooshing thing is just too much.

Any thoughts on how I might attack this problem would be helpful. I realize the SAD has more inherent noise however no way do I believe that all the old SAD chips were this noisy by 'design'. Now, this SAD chip could be in and of itself 'bad' but before I decide that I'd like to try a few things to bring it down some.

I have pics below to see if anyone spots anything out of whack. All the pots work however the one that jacks this pedal up is if I take the Regen past 75% there is an immediate squeal and I don't mean the kind that you go huh and it goes up when you keep turning. I mean the kind that will make you come out of your skin immediately.

Also of note the trimmer nearest the top and nearest the SAD chip is very scratchy while turning.

Thoughts from anyone?

This saddens me. I loved that dudes music. What an original.

I'm sure this has been discussed before at some point but what is your favorite method of stringing guitars? For you flamenco guys I'm talking steel strings  :)

Many thanks to our forum bud Haberdasher for working these boards up for me and in such a timely manner. Guess I'll make twins with these as there is no point having a chip laying around doing nothing.

Thanks Keefe!

I'm sort of piggy backing the other flanger thread going on now but I wanted more eyeballs on my question.

I have two SAD1024's. Is anyone aware of a PCB project out there that employs these? I've searched and have come up empty.
