I was surprised that it sounded good with the 220pF input cap, but I preferred 2.2nF or 4.7nF for a slightly fuller sound. <br /><br />Some of the demos for the Om and the similar Carl Martin Crush Zone have noticeable background hum, and mine does as well. I tried a few easy fixes (small caps off the input or between Q1 collector and base, disconnecting the 2.2uF cap off Q2), but those all muffled the sound too much. The noise floor is not too bad with the gain set under 10:00 or 11:00, which is enough drive for me. <br /><br />If I wanted to build a similar effect again, I might try building a tweaked version of the Punch-in-the-Face, since the op-amp in the Om is not adding much with the gain set low.JDThttps://www.blogger.com/profile/04252685794749449237noreply@blogger.comtag:blogger.com,1999:blog-5481402030233340127.post-5035214840162388992018-10-08T08:55:41.015-04:002018-10-08T08:55:41.015-04:00No that needs to be a n-channel JFETNo that needs to be a n-channel JFETEffects Layoutshttps://www.blogger.com/profile/11341183658959824998noreply@blogger.comtag:blogger.com,1999:blog-5481402030233340127.post-26325195928736115352018-10-08T08:29:39.500-04:002018-10-08T08:29:39.500-04:00How about the q2 sir?
