The crucial mod is to remove the 100uF at the top right. That is the one that couples power supply noise into the 4.5V bias circuit. Several people have complained of a whining noise, which is almost certainly coming from a less than perfect power supply. Removing the 100uF and replacing the 10uF with 100uF fixed the problem for me.

They actually create ppwer filtering issues (which is true in the original morning glory too). Putting it to just the 2 47Ks and the one 100uf mirrors the bluesbreaker power stage instead... And it's cleaner for it too. You still got pots sounding mental noise at full but that's just the circuit. <br /><br />Mod 2: Gain toggle ala V4. Pull the 12K between JFets Source and positive of the 2.2uf. Solder two wires in its place going into a toggle switch. <br /><br />ON-ON: Put 12K one side, 4.5K the other<br />ON-OFF-ON: Same as above but nothing in the middle.<br /><br />You now have high-low gain (and even lower in the middle with the on-off-on).

Im convinced they technically are 2N5457's just not ideal for this application. I havent done this yet but im pretty sure you could add a variable resistor (probably 50k would be ideal) in place of the 22k resistor connected to Drain and use that to bias your JFET. And since reliable/ideal 2N5457's or J201's are harder and harder to come by that could be really helpful if your only able to get current production JFET's. Over all i really do like this pedal but be warned its probably not going to be ideal right away. Mine technically worked first go but it was noisey and needed some modding to get it to where i feel it should have been stock. As for my method of get a second gain stage type option like on the V4 morning glory im not sure how JHS accomplishes it but i really wanted that as an option so i did it the way i knew to do it. If someone knows exactly how JHS did it id like to know. I reached out to them and Zach responded but said all he could tell me was it isnt just a switch that removes the JFET stage in the blue setting (which would be a typical Blues Breaker if you removed that stage). He told me that cause i hypothesized to him that maybe thats how they did it. I also asked if it was another JFET boost (which i thought unlikely but still thought id ask) which he also told me that wansnt how it was done. Thats why i decided to just replace that 12k with a variable resistor. I use a 10k for that Variable resistor/trimmer and its set to about 5k. Like i said before it will work also if you just have the wires connected together without the resistor for the boost position but it will be a really large boost and depending on the components your using and how loud or quiet your pedal is that may or may not be a good thing. If you have any info about how JHS does the boost post it so the rest of us can start adding that to our builds lol! And if you have any questions, comments, or corrections about anything i said here just let me know. Again its a really great pedal once its set up right. Ive been using it for a low gain slight break up boost for "clean" tones and it sounds excellent. But it can also put out a lot more break up. Its certainly a diode clipping type of breakup which i think is why its sounds best as a very light break up as opposed to a heavier drive. To me i kinda see it like if a Tube screamer and a klon/clean boost had a baby lol.minglisnew1967@gmail.comhttps://www.blogger.com/profile/15531063399395675502noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-5090041043120815962020-09-07T17:11:27.082+01:002020-09-07T17:11:27.082+01:00Just built this a couple days ago but i added a 3 ...Just built this a couple days ago but i added a 3 way switch for 3 levels of gain. In the middle position its less gain then stock basically just a regular blues breaker. Then to the right is stock, and to the far left its boosted. I did this by removing the 12k resistor thats connected to source on one side and THE POSITIVE side of the 100uf cap on the other and then I ran a wire to where each lead of that transistor would have been. Then i ran those two wires to the middle lugs of an On, OFF, On switch one wire on each center lug not connected to one another. Then i put the 12k resistor across the lugs on one side of the switch so that in that position it will be stock and on the remaining two lugs/postion you can do one of three things. You can either jumper them together (which results in a HUGE boost depending on the values of your JFET) or you can put a 10k trim pot across the remaining two lugs which will allow you do dial in the amount of boost you want in that position(which is what i did) or you can just used a fixed resistor. If you want to try a fixed resistor id recommend starting with something around 4k - 6k. I really like that i can go from normal BB to Stock Morning glory to Boosted morning glory at the flick of a switch. I will note that there is something very finicky about the way the tone control is connected here. I temporarily wired the tone control without lug 1 connected and just added a small cap to that lug and then soldered the other end of the cap to the back of the tone pot and that fixed it but after awhile my OCD made me want to put it back "stock" and get it working as it was intended. After some trouble shooting I was able to get the pedal sounding right without excess noise but i cant pinpoint one specific thing that fixed it. Ive read many reports of this same type of noise issue. My pedal isnt noisey at all anymore but it took a lot of tweaking to get it that way. Im certain though that a lot of the people complaining about noise with the pedal is turned all the way up are having that issue cause the JFET they are using is being pushed to hard and needs to be biased(more on how to do that below). minglisnew1967@gmail.comhttps://www.blogger.com/profile/15531063399395675502noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-31241544936057652932020-08-30T22:13:41.179+01:002020-08-30T22:13:41.179+01:00This comment has been removed by the author.minglisnew1967@gmail.comhttps://www.blogger.com/profile/15531063399395675502noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-50772075760104367182020-02-04T18:21:53.126+00:002020-02-04T18:21:53.126+00:00If I remove the pump, the pumping noise turns to h...If I remove the pump, the pumping noise turns to high pitched squeel.Anonymoushttps://www.blogger.com/profile/05648278234062248349noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-1854131418464882382020-02-04T17:19:36.002+00:002020-02-04T17:19:36.002+00:00Hi.
