Hi, I did it and it turned on right away. It sounds great, but it's not completely clean (I've never tried the original and I don't know if it's like this; I'll try it out for a while with the bass tomorrow... My neighbors don't hate me yet, and that's fine, haha. Thanks, Fuzzhead. I used the translator for this.
Hello, internally it operates at 24V which must be generated by the 7666 pump. The measurement on my pin 8 gives me 14V and on the positive of the 47uF (Vref) it gives me 7V.
Hi ! I've the original, a friend of mine give me it because there's some problem, the original don't have the 47uF cap, it's a 10uF, the problem is in the Louder Pot, some times don't work till alf opened... I thought so problem is tmin the tl072, but it seems ok
It's finished. At first, I was worried about the low sound, but after double-checking the soldering, there was no problem and I got a great LEMMY sound. There's no unnecessary noise. I look forward to your new products every month. Thank you, Fuzzhead.
Question, since the 10k resistor in 18D/G is creating a HPF, what value for pot or timmer would be recommended to use to have maybe some extra mud/bright control?
It's actually a low-pass filter, shaving off some of the top end where there'd be a lot of fizz and hiss. Adding a pot there is redundant, some it would serve the same role as the tone pot further down the signal path—either that or let back in some shrill nastiness.

Great! Thanks for verifying.

I don't think that this pedal *does*ncompletely clean - that's why it's got an 'off' switch! ;)
DeleteVery informative, my friend, hehe.
DeleteI've built this and it sounds pretty good, but I'm only getting 9v on pin 8 of my TL072 - is this correct?

DeleteI'm not getting 24V, but the design is correct according to the schematic. Check near the pump, bridges, diodes, etc.Good luck

DeletePrueba poner diodos 1n5817 lo vi en varias bombas ,como esta: https://vero-p2p.blogspot.com/2020/07/power-utility-max1044-charge-pumps-and.html
