i just completed building the Mysterioso and i can't get any output at all, bypassed or engaged. i tried tracing the output jack's hot but can't find it anywhere on either of the two pcb boards. btw, i've build 1000's of pedals so i'm not new to this.
any help would be greatly appreicated

hmm. mine looks real. i got it from smallbear a couple of years ago. it still didn't work though.

mine never worked either and i tried another TDA1022P chip but to no avail.

thanks for the offer. i'll probably do that since it's just sitting here collecting dust.

maybe, but i bought it from Smallbear and they're always reliable.

nope. still no chorus effect.

Bummer! i hope you can get it sorted.

that would be great.

so far i've just measured voltages. i plan to put it on a scope & a signal generator tomorrow.

does anyone that successfully built the TDA1022P version have some voltage readings that they'd be willing to share?

if you could be so kind to post your voltages (on the chips for a start) maybe i can get mine working properly.
with a 9 volt benchtop power supply, i am getting +13.4 volts on pin 8 of the TL072's and LM 1458 and -13.4 volts on pin 4. i'm also getting -13.4 volts on pin 9 of the TDA1022P.

yeah, i'm sure that it is okay. i'm just trying to figure out why mine's not chorusing/vibrato-ing.

i just built my TDA1022P version yesterday. the bypass & volume control works as well as the LED's rate flashing with the rate pot, but i have absolutely NO chorus effect. I've checked and re-checked everything but to no avail. i had really high hopes for this one.

Any bass players on here tried the Lovetone Big Cheese? That does a nice gated guitar, don't know about bass. Plus it has other modes, too.

yes, i've built one but i added a bass ("fat") boost to mine and it sounds great for bass that way.





here's a quick & dirty clip noodling and trying different settings:

i had a bad ground on the fuzz pot. DOH!
