Used B25k for the Hard pot and B100k for the soft. Lot's of sustain, gain and distortion. Couple questions though.<br />Seems like the soft doesn't do much prolly cuase of the pot switch, but the real issue is the fat pot. Turning it higher than 1/2 way and it whistles pretty good, and then the filter pot changes the pitch a little. It works really well otherwise, but I'm curious if there's anything I can look at to address these problems.<br />Any suggestions would be greatly appreciated. Oh I used your etch pattern and made a pcb...<br />pgphilghttps://www.blogger.com/profile/15239793845414714132noreply@blogger.comtag:blogger.com,1999:blog-5481402030233340127.post-20017873416845994172020-04-20T15:02:53.639-04:002020-04-20T15:02:53.639-04:00where is the pcb? pleasewhere is the pcb? pleasewacharatehttps://www.blogger.com/profile/07040177179971720111noreply@blogger.comtag:blogger.com,1999:blog-5481402030233340127.post-74185871702360186462019-12-26T14:26:47.359-05:002019-12-26T14:26:47.359-05:00AlexS was rigt, better take b20k& b100k!AlexS was rigt, better take b20k& b100k!

Since it's for clipping, I've found other values I prefer when experimenting with other VFE builds.<br /><br />On my build of this one, I just used on/off/on switches instead of pots. The earlier version of this pedal did just that.<br /><br />AlexShttps://www.blogger.com/profile/05624907590644025643noreply@blogger.comtag:blogger.com,1999:blog-5481402030233340127.post-68104460363699536712019-12-23T11:14:13.392-05:002019-12-23T11:14:13.392-05:00verified!

I also think we can best use linear (B) type pots and a B250k for the "hard" pot this does change the values a bit, but I doubt it will be noticable. You couls also use a A250k with a 1M between lug 1 and 3. It will make the taper more linear but still keeps a bit of the A taper feel.<br />And lastly, a B1M for the "soft" pot.Arnold Dikstaalhttps://www.blogger.com/profile/00591790612241477571noreply@blogger.comtag:blogger.com,1999:blog-5481402030233340127.post-77332366711504552302019-12-21T02:18:56.921-05:002019-12-21T02:18:56.921-05:00You can get W Taper (Anti-Log) pots from here

Any sources?<br />I do not see why it uses a W200k pot as it is not "standard" in both value as in taper type.It is only used as a warp control like described by AMZ (http://www.muzique.com/lab/warp.htm).
