Linear pots were kinda useless for most of their rotation, with logarithmic pots the sweep is more useful. Changing the Gain pot to 250k increased the maximum gain nicely without going over the top.Jupnitski77https://www.blogger.com/profile/11582075821084193973noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-3276282297460945322018-08-15T02:37:23.054+01:002018-08-15T02:37:23.054+01:00Can you point out which caps are C5 and C11 from t...Can you point out which caps are C5 and C11 from the original circuit?

Maybe you need to consider adjustments to the setup you use to find the sound you are looking for, the pedal is only one part of the equation. I don't have much noise out of either my original pedal or the one I built from this layout, both sound identical, only slight noise when you crank up the gain and level as you'd expect on an overdrive. You'll have to check your build for faults, you may have a loose ground or some sort of short causing the "chuck". I have built 3 from this layout now and I am pretty pleased with them!Chancehttps://www.blogger.com/profile/03508039283950531588noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-34586041658477968322017-10-21T12:13:31.780+01:002017-10-21T12:13:31.780+01:00Hey guys, I build this pedal and it sounds really ...Hey guys, I build this pedal and it sounds really good. I like the response to guitars with Single Coil compared to Humbuckers. I have 2 questions:<br />1) the equalizer seems to need very extreme settings for me to sound good. I usually turn Highs all the way down cause it sounds too bright otherwise. And Low needs to go all the way up to have a nice and powerful bottom. Is this specific for the pedal (can you verify this?) or might I have soldered something wrong?<br />2) the background noise seems pretty high as well. Same question. Is this normal to the pedal or may I have messed up something with the grounding wires? Also switching on the unit gives quite a loud "chuck"Andréhttps://www.blogger.com/profile/04103236221643706092noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-77270617883849141022017-03-27T06:16:41.882+01:002017-03-27T06:16:41.882+01:00And about the schematics?

Usually the layouts use schematics from either freestompboxes.org or DIYstompboxes.com. You do have to be a member to access and search for schematics on these websites but generally you would be successful finding the exact scheme used for a particular layout. <br />All it takes is a little effort.

The Low alters the volume throughout it's entire range, the further clockwise the louder the pedal gets. The High control gives a big volume boost when turned fully clockwise, not so much until the end of the rotation. <br />Seems odd, is this by design or do I have a fault somewhere?

This layout certainly works so chalk it up :D <br /><br />The active EQ make this one a little different from most other overdrives so definitely worth looking at and tweeking.

I was tempted to take it to ground anyway because it was 2 rows away and so better suited for 5mm pitch caps but decided I should follow the scheme.
