For any other newbies like myself taking this project on, I have a few crucial pieces of advice:<br /><br />1) Read the comments carefully. All of them. Most of your questions will be answered somewhere in the comments. <br />2) If using SPDT switches, do not ground them. I did this because I had the extra lugs and I assumed I should ground the switches like everything else. Wrong, wrong, wrong. If you do this, your circuit will not work. This was the main problem I ran into and believe me when I say it took hours upon hours to figure it out. <br />3)Use a much smaller value cap at Q1 source; if you use 10u as instructed in the layout, your 'fat' switch will do nothing (you will find many comments complaining about this). One commenter recommended 100n. I used 220n (what I had on hand) and think the fat is plenty fat.<br />4)The 'bright' switch is subtle but definitely noticeable. If yours isn't doing anything at all then something is wrong, but really give it a good listen and cycle through your guitar's pickup configurations before you decide it's not working. I personally found mine immediately noticeable.<br />5)Some commenters say this will fit into a 1590A enclosure, and they're not wrong. It might be easy for the more experienced among us, but if you're new to this like I am, use a 1590B. I spent practically an entire day trying to get everything to fit into a 1590A and it was maddening and unsuccessful. I tried again with a 1590B and it fit easily but without any wasted space.<br /><br />I hope others will avoid some of my rookie mistakes! I appreciate this website a lot, I'm having a blast making these pedals.

Either way, when I fixed the cap, the output was way too low to drive a high gain amp properly (sounded like it was on the verge of breakup). I think that there was ~4v difference on the drain. <br />I have also swapped out the 8.2k resistor with the 5.6k one and removed the fat mod as I didn't like it that much. The resistor mod is to avoid +3dB boost on the output because I'm planning to use it as an always on pedal.<br />In case you want a dip switch to choose between 3dB boost on/off, you can do it fairly easy by running something like a 15k resistor in parallel with the 8.2k one. The idea is to jumper the 15k resistor to 8.2k while the switch is on.pavlebnhttps://www.blogger.com/profile/02438411776365232704noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-80991864387892671132018-11-21T20:24:46.971+00:002018-11-21T20:24:46.971+00:00I know it's been a while but I'm intereste...I know it's been a while but I'm interested in how and if you got it to work.

I am using it on breadboard and can't hear a damn thing unless I turn the amp volume and gain all the way.<br />Instead of 2n5457 I'm using bf245c. It may be the culprit since the pot doesn't seem to do anything. (Can't be biased correctly or whatever, this is my first pedal and I'm fairly new to this stuff so I might be talking nonsense) I'm gonna wait for 2n5457 to ship and try replacing it then.<br /><br />On the other hand there might be something I'm missing, so I will send you the picture of breadboard soon.pavlebnhttps://www.blogger.com/profile/02438411776365232704noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-53502988072176392762018-10-30T15:55:46.819+00:002018-10-30T15:55:46.819+00:00it sounds like overdrive. i use the same component...it sounds like overdrive. i use the same components. problems with q1? do i need to change 33K resistor? please help - what can i do now?oshunhttps://www.blogger.com/profile/08055672951877672879noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-78945791544751433752018-10-22T18:20:57.046+01:002018-10-22T18:20:57.046+01:00on the 4th line, why you did that cut?

Instead it has Unity gain switch. Once it is on it will give +3dB when Boost pot is at Min position. Resistor 8,2 k is exactly chosen to give +3dB. To have unity gain this resistor should be switch to around 5,2 k. I used Fat switch (SPDT) to choose between those resistors thus it gives newer ver of EP booster.Iczikohttps://www.blogger.com/profile/01820509657980412941noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-16598438194493876002018-04-27T12:33:54.739+01:002018-04-27T12:33:54.739+01:00This comment has been removed by the author.SV112https://www.blogger.com/profile/13198808244584075224noreply@blogger.com
