It’s now working

Trying to login to order pcbs and getting error from Cloudflare. Any tips?

For those that have modified this with LEDs, what have you found lacking? There is definitely a difference in response I can’t put my finger on but, quite honestly, I think it sounds great and rests well in my band mix. Admittedly my ears are not as discerning as others! FWIW, I test all pedals...

Using red leds, while reducing gain a little was the trick for me. Perhaps more discerning ears could pick it apart but I wouldn’t use this pedal at its highest gain anyway. I build all pedals using a Friedman SB50 in plexi channel as my base sound. The nine ball does really sound great thru it...

Also what would be a good starting point and range for R17 values? Like 12K-20K?

I socketed some red leds in D3/4. Definitely more volume and a little less less gain but sounds great to my ears. I’ll experiment with R17 and report back. Thanks so much for the advice

That makes me feel a little better! Any thoughts on what can be modified to get some more volume?

Thanks for replies. I’ve confirmed, I’m pretty sure that values past 3.1 are correct. Closely inspected under magnification there are no obvious bridges. Has anyone put this one together that can say for certain that there should be gobs of volume on tap?

Assembled and boxed the Nine Ball yesterday. It honestly sounds great but, in at least my build, with volume all the way up and gain halfway, it’s just a smidge below unity. Is this inherent to the circuit or did I likely do something wrong

Thanks! That’s a relief considering all that’s needed in BOM. Out of curiosity, using a Bat 46, what scenario would create a failure of regulator?

What potential issues may arise using Bat46 in place of Bat48 in D4. 48 has forward current of 350mA and 46 has 150mA. I plan on completing this over weekend and I’ll just socket D4 since I don’t have 48’s unless distinctly contraindicated.

Now I’ve noticed the hum!! Before boxing it up I played around with it and it sounded fine on its own and I figured it was good to go. What’s strange is how loud it is with a blues breaker circuit. Literally unusable. Sounds dead quiet with Greer light speed. Klon circuit it’s mildly noticeable...

I mean I kinda figured as much. But as it’s built, it already sounds pretty great. For a tone shaper it’s nice to have in the arsenal.

Sooooo….. while browsing for something unique saw glowing reviews and put it together. Sounds great. Then, I saw all of the discussions! I had no idea of the history. Very entertaining I did not build using the BOM just silk screen values so tantalums are now electrolytic. Would it be worth...

Thanks. That’s a relief. I’ll definitely need have to make some creative bends and insulation.

I do not currently possess a 78L12 voltage regulator for my valhalla build however my understanding is that the 7812, which i have, will also provide 12V. Aside from the physical size difference and ability to handle higher current, is there any reason i couldn't still utilize it?

Thanks so much for your suggestions. A jumper from pin6 to R17 resulted in a sputtering gated mess despite any position on gain pot. Given that and the mid pot dysfunction I have a feeling we’re dealing with multiple issues. Nothing I’ve done, from reflowing, changing ICs, cleaning, staring and...

Thanks! No continuity between pin6 and R17. However continuity between the other two listed

After successfully troubleshooting other builds, this one has baffled me. So gain pot and the mid pot do not function. I get a fairly gainy, even pleasant, signal but only the vol pot controls it. Interestingly, I get 4.45v on each of the mid and gain pot legs. Also, I’d replaced the gain pot...
