- Incr...I have some sugestions that worked for me:<br /><br />- Increase the 220pF of the grunt switch to 470pF<br />- Reduce the 4049 feedback resistor from 470k to 330k<br />- Increase the 100R 4049 supply resistor to 1k<br />- Also make a boot's trap before the 9V input of the board, it means, put a 100R in series, like the rat, that gonna improve the noise performance<br /><br /> Yet, all these mods didn't worked well to me, and the pedal was more like a gate distortion, the oscilations stopped, but it could be more, I espected it.<br /> <br /> So, my final solution was to replace all the 4049 section, to a mosfet muff distortion block, and gess what? Sounded lika a charm! ahahah No oscilations, giant sustain, all the switches did they role super well, I'm super gratful to all the mates that inputed so much information about this thread, that's my 2 cents.Pedro_Marizhttps://www.blogger.com/profile/00690779330980806281noreply@blogger.comtag:blogger.com,1999:blog-5481402030233340127.post-35552925856255873672019-09-26T04:37:15.491-04:002019-09-26T04:37:15.491-04:00Hi! i have an issue.
