I didn't have a 470k pot, so used a 500k and put a 6.8M resistor between lugs 1 and 3 as suggested in another comment. That one didn't work for me, signal still cuts out when fully rotated, but it's only for the last 5% of the way around, so pedal still very useable. Self-oscillates happily, allows for some weird and fun noise making. Loving it!

I assume the 1 is the left hand side with the tag with the pot facing me, is that right for this build. <br />I do get a guitar signal currently, but when I turn the pots up the signal isn't heard and I get crazy delays. It sounds like the chemical brothers.<br /><br />Can I take photos and share ?

Thanks to mirosol IvIark (whose name i was pronouncing ivark , in my head of course for a few months -ha ... is he russian ? maybe ? maybe i am just silly ) anyway i always do my pots looking at the ass end with the shaft going away the one two 3 left to right where i have noticed these layouts are often revered . on two occasions i have attempted to beat the system and not have to redo all the pot wiring and on both occasions the wiring was reverse of what it normally is on this site . love it ! (so i had to redo the pot wiring ) my helper pulled a 500ohm pot instead of a 500k for this build , love it! she is right now re-soldering all the pot connections for me as i need a break . thanks for all your work guys , i am getting really damn good at pot wiring . which i am going to try to solder a 6.8m resistor inbeteen legs 1 and three of a 500k pot as i do not have a 470k pot . tat seems to be really important on this one . if you finish up and you arent getting much echo , try connecting your amp to lug 12 (4th up from bottom on lh side) and check for echo there . thanks again love the site and great work !petey twofingerhttps://www.blogger.com/profile/06740368817236312111noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-79383159103610360562016-11-06T16:11:40.343+00:002016-11-06T16:11:40.343+00:00I Have a strange problem with this one...
