Other than those issues, it sounds amazing!ptonehttps://www.blogger.com/profile/10004836636351001856noreply@blogger.comtag:blogger.com,1999:blog-5481402030233340127.post-86389059495259568812022-01-29T07:06:59.177-05:002022-01-29T07:06:59.177-05:00Excellent, it sounds very good.

Be careful. After soldering test the potentiometer with a multimeter to be sure that it is still working good. For easier soldering spray some contact cleaner with oil on the pot before soldering...<br /><br />Thank you for the layout.

If you're having problems with the mix, check the tone and mix pots and all the parts on that middle track that attach to the tone pot.

I probed different areas on the IC and had audio at Pin 9 (op1 out) and Pin 15 (LPF1 out). The audio path to pin 15 and 16 had audio. There was some signal at the repeats section. Any ideas why it isn't working? I'm also gonna try more PT2399s just in case.marlo830https://www.blogger.com/profile/07104056520402917471noreply@blogger.comtag:blogger.com,1999:blog-5481402030233340127.post-52280670557260432772019-04-05T09:58:28.809-04:002019-04-05T09:58:28.809-04:00Hi guys! cant get self-oscillation at max repeat l...Hi guys! cant get self-oscillation at max repeat level and even when i lock leg 2 and 3 together. does anybody know how to get it? thanks!fidel rodriguezhttps://www.blogger.com/profile/16366367384180943511noreply@blogger.comtag:blogger.com,1999:blog-5481402030233340127.post-25612898755604913082019-03-12T08:58:21.396-04:002019-03-12T08:58:21.396-04:00Hello, I’ve made this delay pedal with «Soft-Latch...Hello, I’ve made this delay pedal with «Soft-Latch Relay Switching» and it works, but when I switch it off there’s a pop.
