This is seriously cool! Well done, both of you. I feel like garbage, so I sat laid down in bed and started adapting the mayonnaise fuzz mods/controls to the deuce. Won't breadboard them until I can sit properly, but there's a good chance at least one of the switches is placed wrong, as well as values needing tweaked, but it's the first bit of creative juice I've gotten in a while.

Seriously.

Great bit of history there! But man, what can't we trace back to Jack? Thanks, Brian.

I've been looking around at the various MOSFET based circuits out there, mainly from "What can I build?", and came across some things, all probably old news and deep lore™

I ducked out of DIY in 2012/3 and came back about a decade later, for reference. I found a couple of posts here, but wondered if anyone can share light on who made the MOSFET boost first, because the circuits are looking rather similar. Obviously, only a few components can constitute a big difference, and maybe I'm nuts.



I was looking at the Firecracker, Landgraff Clean Boost, and z*ex SHO, and wondered if one came before the other. I tried backtracing the Firecracker from mirosol's tagboard, before finding what appears to be the original schematic, with a "this is for DIY only" disclaimer. I'm out of it enough not to know when John debuted his boost. And I only know that, like many others, if you use the brand or circuit name on a Reverb ad, you get a takedown from the ghost of Randy Savage.

Firecracker has a different biasing method, from what I see, but some of the bits look very similar.

Nicely done! Clean and spotless in and out.

I really like those GE germs, too; classy, mid century brand aesthetic for the curious ones opening up the box.

1590A

SHO

I couldn't bring myself to do SMD, but I was inspired to make a one knob, mosfet overdive!

Lol that file name. So 1590F is it? 

Jokes aside, nice work!

One of these days I'm gonna put a moseft boost in a 1590XX just to spite you! 

Stellar as always! Even if the box is too capacious  

what ever happened to the pcb, pdf etc? been looking for it and the drawing above also references the schematic i found that bean posted a couple years ago. trying to work out what was modded so maybe i can teach myself. finally.

I believe the corrected schematic linked in the post above is where it's at. might start by comparing it to Robert's 1:1 trace to see what the mods are.

Far as a board goes, the one layout posted earlier in this thread might be a jumping off point, but might not be based on the final schematic Bean posted above.

Reading this makes me want to go back to my Harbinger 1.5... I wonder if my cheap 5088s are the problems. That poor thing has been in an esd bag for years now 

That's dope. Do you have s favorite between the two slopes? I've never experimented on guitar before, only synths way back.
