I found that my bottom rail wasn't grounded. It's a little double jump coming off the long ground jumper. Missed it. Now it sounds great! I hate it when a pedal works, but isn't right. That ground jump made a world of difference!

I read on a diystompboxes forum that you could, as long as you knew the drain current you wanted, which I'm not sure how to find for this pedal.

To get that sound, I have to have the volume maxed and turn down the Master appropriately. I'll play with it a little more. I biased the trimmers to get 4.5V at all four drains. Hmmm. I aslo used Miro's mods. The switch is extremely subtle.Mojo321https://www.blogger.com/profile/09952527923804212583noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-72179507210101245662013-12-12T04:00:18.385+00:002013-12-12T04:00:18.385+00:00Thanks.

Now, I have correct value of 9.5 V for a brand new battery and 9.63V for my 9V DC alim bloc. <br />It is not the solution of my problem, but a necessary step to have a chance to find something. <br /><br />Here as my values after biasing the pedal. <br />DC alim : 9.63V<br /><br />Q1 : D:9.61 (new and BAD !!) / S:0.23 / G:0<br />Q2 : D:4.24 / S:0.29 / G:0<br />Q3 : D:9.62 / S:4.26 / G:4.5<br />Q4 : D:4.82 / S: 0.23 / G:0<br />Q5 : D:4.61 / S:31.9 mv / G:0<br /><br />It seems that I have a problem with the trimmer from Q1 (defect piece and/or bad soldering). I will check that first and see the influence on Source from Q4 (0.23V is a lot too low ?? I should maybe try other value for the 4k7 resistance ??)manu684https://www.blogger.com/profile/17486940773925248351noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-62781778866540987642013-09-01T21:31:36.398+01:002013-09-01T21:31:36.398+01:00This comment has been removed by the author.manu684https://www.blogger.com/profile/17486940773925248351noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-6649928519170844142013-09-01T21:19:50.156+01:002013-09-01T21:19:50.156+01:00Hi everybody.
