"Little Angel" - Super Simple PT2399 Mini Chorus

[Earthscum]

2-5k pot with the 100R as a limiting resistor works great. I use 10k, but I'm a bassist with a weird sense of sound.

Page 8, second post down has the mods that I find useful and use.

Yea, actually I did do those mods, I used a 5K with a 100r limiting resistor, but that seems to affect the delay time, not really the depth.. Unless I've done it wrong somehow..
Also, the level mod you showed doesn't seem to work for me.. It doesn't seem to adjust the output signal at all.. I need to look at that again, but I think I did that right also.

Whenever I hear 'not enough depth' I think maybe there's something wrong, as I tweaked the design for what I considered gave just a lttle too much depth. Is the opamp Ne5532? Anyway, reducing R13 or replacing R13 with a jumper will increase the depth to too much/way too much respectively.

[thehoj]

I am using an Ne5532, and I've actually got a 30K resistor in place of R13. I'm probably just looking for more versatility than this pedal should have.
I'll try a few different values though. Thanks.

Works Great! Just the basic build no mods and it is sweet. Into the 1590A tomorrow and pictures. Thanks Rick!

[frequencycentral]

Damn! I was hoping to complete the first 1590A build. I'm just in the process of producing the etched enclosure. I'm about two days behind you.....

[roseblood11]

Great project!

Has someone made a vero layout in the meantime? Renegadrian talked about that, but it seems he never finished it?

[deadastronaut]

+1....great sound on that clip rick.....very cool project.....

been following this thread, waiting for the dust to settle on the inevitable mods....

i'd like to see a vero too...coz im too lazy to 'print, saw, etch, n drill'.... rob....

[Pigyboy]

Ok, It fits in the 1590A. Is this the first finished mini-box build?  It gave me fits getting it in there. It won't fit with sockets or anything taller than 7 or 8 mm above the board. It does fit clean and it sounds beautiful. I will make a clip today. Looking forward to Rose (my wife) using at her next gig with her new Taylor . That is if she doesn't want to use it to sweeten up her Little Angelic voice. I think I will get her to help make the clip doing a proper guitar and vocal demo.

What? No battery? 

[frequencycentral]

Here's mine!

[Pigyboy]

Wow Rick! . Looks great. I couldn't get mine in the box with the sockets. What kind of jacks did you end up using?

Hey
I'm  mewby, and tried a veroboard layout for the Little angel circuit. It's my first time going from schematic to vero layout, so I invite anyone to examine or try it.  I will order the material just tomorrow, so i can try not before 10 days. Can anyone see anything wrong?

[Mr. Slave]

sorry....

cuts under the ic?... .....

Interesting. I like the simplicity of the circuit. A board wouldn't even be necessary, unlike most other chorus schemes floating around out there. What opamps did you use?

i was looking forward to this interesting boardless version of this build  

[Mr. Slave]

Of course....
cuts under the ics....

[frequencycentral]

sorry....

I find vero really hard going, but I spotted a couple of errors (there might be more, I didn't check it all):

• IC2 spacing incorrect, should be 4 x 4.
• C6 should be from pin 8 to ground.

It would also help if you used the correct DIYLC part for the electo caps, to avoid incorrect orientation.

[Mr. Slave]

New vero with corrections

Thank you Rick....

[deadastronaut]

c5 should be to ground .
cuts under c12??why!.

i think we would all be better off doing the pcb. looks like it might end up big , and maybe problematic, etc..

nice to see mr slave  have a go at it though!..it took me a while to get used to converting from schematic
to vero, you didnt choose an easy one by the way!.... rob.

[Mr. Slave]

Thank you Rob
"c5 should be to ground"...that was an oversight
"cuts under c12?why!" ... I moved everything but the cuts under c12
...soon correct layout...
