I have a request: Nocentelli helped me figure out how to recreate the Clari(pirate) - Pitch Pirate deluxe + Clari(not). PLUS Doug, mr Mid-Fi himself, contributed a few corrections to the pots used on Pitch Pirate. It's all here: https://www.freestompboxes.org/viewtopic.php?f=7&t=30867&sid=eee98447c1d7c420b66891b0d4344f44
See that you've since made the layout!ure, the DBA completist in me is excited, but honestly O think I have thr ground covered with a Pharaoh Supreme and a DBA apocalypse.
I'm, however, eagerly awaiting the buil docs for PedalPCB's Shallow Water clone https://www.pedalpcb.com/product/pcb406/
hey Sesh! Finally staring on Clari Pirate. You don't happen to know how accurate the schematic at FSB is? There is aresistor and pot value missing. Also Doug's comment about the Delay control confuses me a bit....
The schematic is not for the Clari(Pirate) per se, but some DIY'er over at Madbean's own expansion of the Pitch Pirate Deluxe. Nocentelli just posted it to show how the concept of adding the envelope to the PP Deluxe. I don't really know or understand how to implement it, though, sorry!
I noticed he said he ditched the LM386 and the dual gang blend, though, so the schematic in this layout is probably "obsolete". I think we're better off waiting for Doug himself to post the real schematic (as with the Pitch Pirate standard) or work it out based on the PP standard schematic and simply add first the Deluxe controls and the Clari-envelope.
I've been over the schematic a couple of times now. https://www.pedalpcb.com/docs/PitchWitch.pdf The only mistake I could find was the lug numbering for the Depth pot. The layout has been updated. But it doesn't explain the noise issues you have.:-/
Well, just had a mess around with the circuit. Your amendment to the numbering on the depth pilot totally fixed the LDR/LED issue. It now pitches all over the place.
However, the hiss is still there. I'm going to try different opamps and see if that makes any difference. I may have a dodgy chip.
I was comparing this to a verified layout and it looks like the feedback portion of the circuit isn’t correct. Feedback 2 should hit a 15k and then 2x anti parallel 1n4148’s then back to the 386 input - on this layout, the diodes are connected to ground on the 78L05 ground row. You could fix it by moving the 2 long ground links to the left of the 2399, the short pin 3/4 ground link under the 2399 and then putting a cut to the right of the ground link on the 78l05 ground row. Sorry, I’m on my phone, tough to grab exact row/column numbers. I know it’s an obsolete layout per the FSB discussions, but MidFi hasn’t gotten around to sharing the revised schematic - it’d be nice to get a good compact layout of this.
I may be wrong too - let me know if I’m missing something.
Verified. Once I saw the new depth pot layout and I fixed my stupid dual pot wiring mistake, it came to life. I'm not hearing any background noise or other issues. The rate pot works backwards on mine.
No it's the rate pot thats bachwards, as in it goes slower as you turn it CW. The reason my depth pot didn't work at first is my own fault.. I mistook lugs 1 and 6 and lugs 3 and 4 as being directly in line, not on opposite ends forming an x.
It could effect the way the pedal "modulates". I haven't built the Deluxe but the standard PP wasn't overly particular about what LDR I used. I'm sure I just used some random Tayda part. The Pitch Pirate is a pretty great PT2399 based effect IMHO. From crazy and unusable to fairly classic and subtle.
Its not clear on this circuit that the yellow LED is in rows O and P... it's got legs coming off it hanging over rows N and Q. I misread and miswired it.
This build works for me except that the LED(s) will not flash. The LDR is fine as it reacts to light manually. Other layouts have mention of specific wiring to footswitch ground in order to get the LED to flash but I'm having trouble translating it to this layout. Based on other layouts I have seen, is the LED+ supposed to be connected at the ) row, rather than N? That way it's after the second 10k (K5 to O5).
Thank you. I misunderstood Chris' earlier comment. I moved the LED legs to O and P but...same problem unfortunately. It no longer does this thing where the depth pot in the first quarter turn lights up the internal LED and past that the indicator LED lights up. They both stay on the whole time now.
I have cut the track, cleaned with alcohol, double checked my build and I'm still getting crazy pitch effects but no flashing LEDs. The speed and wave pots don't do anything I assume since the LED is not flashing, they have nothing to control?
Thanks, I appreciate the confirmation. I was detecting continuity on the opposite sides of various cuts so I figured I had to messed something up, even though I tend to mark off a piece of paper when I build now.
I examined some photos I took in stages when I started building this a few months ago (easier to examine without all of the components crowding) and realized I was missing a link at F10-H10. Now it flashes! Thank you all!
Got clean signal but no effect. 11/17/2020

Cool! Will take a look but it will take a few days until I can dive into it.

I know you are a DBA fan. What do you think about this???

Good man!
ReplyDeleteA small headsup. Was not satified with the old unverified layout so I did a new more compact layout from scratch. Still unverified, though.
ReplyDeleteJust tried this fella.
ReplyDeleteIt's not quite there yet. Have built that standard Pitch Pirate and love it.
This circuit however has a few issues.
Firstly, it's noisy, a loud pronounced hiss that is almost as loud as your guitar signal.
Secondly, the LDR/LED don't appear to do anything. There's no pitch modulation at all.
Thirdly, if you go too far on the delay and feedback pots, you get ear shredding delay feedback noise at about five times the volume of the pedal.
The layout for the Pitch Pirate works a treat, but I could not get this one to work.
I've been over the schematic a couple of times now.

Thanks for the input. I will take a closer look during the weekend!
DeleteThe layout is based on this schematic:

Been over it multiple times now and I just can't spot any errors. :-(
Verified.

Thanks! It is now tagged.
DeleteNot sure about the the reason why the Depth pot acts backwards. It could be a schematic mistake?
No it's the rate pot thats bachwards, as in it goes slower as you turn it CW.
DeleteThe reason my depth pot didn't work at first is my own fault.. I mistook lugs 1 and 6 and lugs 3 and 4 as being directly in line, not on opposite ends forming an x.
Does the value of the LDR makes a lot of difference on the function of the pedal?
ReplyDeleteIt could effect the way the pedal "modulates". I haven't built the Deluxe but the standard PP wasn't overly particular about what LDR I used. I'm sure I just used some random Tayda part.

ReplyDeleteLED connects to row O and P, then it will work fine

This defo works, I've made a few of these without issue. The indicator LED does not flash also
