Try something like 2k2 to see what that does, then tweak from there if its getting closer to your liking. You can also try adjusting the 680R.<br />MAOhttps://www.blogger.com/profile/16009444316767677263noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-88710217020584743532022-12-05T20:02:10.966+00:002022-12-05T20:02:10.966+00:00isn't 22u super bass?isn't 22u super bass?Ghanoxhttps://www.blogger.com/profile/05092007459165435220noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-91673098863114245672022-12-05T18:21:27.303+00:002022-12-05T18:21:27.303+00:00This comment has been removed by the author.MAOhttps://www.blogger.com/profile/16009444316767677263noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-91892404988834757932022-12-05T17:34:48.616+00:002022-12-05T17:34:48.616+00:00Hello friends! tell me how to reduce the gain leve...Hello friends! tell me how to reduce the gain level in super lead mode? changing the resistor from the 47k gain potentiometer to ground just reduces the volume. how to reduce distortion?Ghanoxhttps://www.blogger.com/profile/05092007459165435220noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-52277114540212164202022-10-12T06:55:04.546+01:002022-10-12T06:55:04.546+01:00Thanks! at least i know it worksThanks! at least i know it worksGhanoxhttps://www.blogger.com/profile/05092007459165435220noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-15989587647767309792022-10-11T23:41:49.049+01:002022-10-11T23:41:49.049+01:00Hey man.

There is sound, but little distortion. Also the sound is quiet. at maximum Gain. If Gain is lowered, there is almost no sound. If you remove Q4, then no changes occur. If you remove Q5, then the sound becomes loud, but there is also little distortion. What could be the problem? Voltage doubler version. This version works, is it tested? What could be the problem? I will be grateful for any help.Ghanoxhttps://www.blogger.com/profile/05092007459165435220noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-24483409965350278652021-12-15T17:28:38.816+00:002021-12-15T17:28:38.816+00:00I believe the presence cap should be 10nf, which w...I believe the presence cap should be 10nf, which would give a upper frequency rolloff range from about 1.5kHz. And around a 3kHz rolloff with the trimmer set in the middle. <br /><br />The 100nf cap has a rolloff starting at 159Hz, and 318Hz with the trimmer set in the middle. IMO too low for a presence control.

If it's all ok I'm gonna source some PN4393s and try those out too.<br /><br />Cheers to Mirosol for the assistanceelbeeukhttps://www.blogger.com/profile/07120739147011219424noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-59264745536450296252017-09-06T18:36:41.053+01:002017-09-06T18:36:41.053+01:00Forgot to add, my power supply reads 9.11vForgot to add, my power supply reads 9.11velbeeukhttps://www.blogger.com/profile/07120739147011219424noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-71946718399533180742017-09-06T18:35:10.618+01:002017-09-06T18:35:10.618+01:00I've recorded the readings on each 5487.

The linear taper for volume might be enough to fix the feel of the control.<br /><br />How's your guitar?
