Title: fat boostered problem
Post by: m-theory on September 09, 2008, 08:39:12 AM
I built a fat boostered from this layout:
http://www.indyguitarist.com/torchy/Boosters/GGG%20Fat%20Boostered/Fat%20Boostered.GIF

Everything works perfectly EXCEPT the treble pot, which seems to act as a backwards-wired volume control...fully left is full volume, fully right is no output.  In essence, I appear to have functioning gain, bass, and two volume controls. 

Any thoughts offhand as to what might be going on?

I don't think your treble pot is wired up correctly.

It's wired according to the layout.  I'll check the schematic this evening.  I notice by the schematic that the treble pot comes right before the volume pot, so I've got something goofy in there, for sure.

Hi! I think lug 1 of R8 goes to Ground and lug 2 and 3 are together. So R8-1&2 become R8-1 and R8-3 must be R8-2&3...something like that!

What is this pedal exactly?  Is it basically what Fulltone stole to make the Fat Boost?

I think it's a Jack Ormann mini-booster with gain, treble and bass control...Don't know about the ''Fullstole''

Wellllll, that's an old, old story so I didn't mean to open up that wound...
Edit:  Okay, I see the difference between the Fat Boostered and the Boutique Boost on GGG now.
