Not that I want to clone it, but some kind of simple mosfet clean boost.

...design your own Booster type articles depict examples of what  can be done with mosfets and Jfets.
   There's been talk that the SHO is not a shared schematic, There's a price hitch some Ppl have about owning ZVex sound shaping devices.
  I would suggest trying one out and seeing if you can match or beat it...
  I just built a RangePig or Piggybacked Treble Booster, great build.
  Trying one booster into the other and tweaking gains and linear swing is always fun stuff...plus you start really finding interesting tones along the way.  
   Weren;t you working on a FF a while ago? Did you get that FF going?

I should go over that article again, in greater detail. I do have a working circuit similar to a FF, only with silicon transistors, and a clean blended output, as well as a slightly different voltage controller.
I still have my good old Zvex fuzz factory though!

Draw up some draft schematics from what's there at GEO.
 I like the sockets in perf for R values that I want to mess with...that or trims ... just to see what 'that' actually does. You can always jumper !

Theret are a lot of booster designs that use a BS170, and are real similar to the SHO. For instance the mini booster that Jack Orman does.

The plus about his design is you don't get the static across the pot.

theres also the one that z debunked for us  someone claiming it to be a sho.   it isn't a sho, but it is a nice sounding little unit.

The Jack Orman *AMZ* Mosfet boost is a wonderful circuit. Jack recently took pains to point out that it is NOT an SHO, and that Zach Vex builds wonderful stuff that is wonderful to own (I agree) , but if you are looking to roll your own mosfet boost, it's the way to go. As a DIY project, it gets my vote as "Most Essential DIY Build" , because of it's ratio of build simplicity to versatilty/usability/musicality.

I wish there was a way to post images from your HD on this forum, because I want to know if the schem I have thats labeled SHO is the one Zvex debunked. The one I have looks like it would blow mosfets, so I never used it.

The one Vex debunked will have the same issue that his does, and that is static across the pot.  The debunked SHO has some differing parts. I wont mention what they are here, but they do make a difference in the tone of the circuit.

I just wanted to make this clear. I never said nor will I say that the AMZ Mosfet Boost is the same as the SHO. Zach makes great stuff as well as Jack Orman. They are similar. The meaning of similar is close, but not the same. Like you can say that all beer is similar, but not the same.
