I bought a 535 a long time ago, and never bothered to investigate why the boost didn't work.   Now that I know a _bit_ and decided to have a look, it looks like pot to control the boost isn't connected to anything!  There are also some places where caps have been left off.  If anyone could take a pic of even the bottom of this PCB, I would appreciate it.  (Or if there are any on the 'net already, please let me know.)  

Thanks!

Ok.  Some pics...

On the front , you can see some places for caps-->


On the back, it doesn't look like the boost pot is connected to anything!-->


It doesn't look like this would be hard to fix, I just need either a schematic or some decent pics...

TIA!

I thought most the new ones are built with SMT's...

BTW- SIC- i might be bale to send a few pics if u still need them but after reading your post..i think mine is different than yours..

Thanks alot

I think my wah is from ~'95.  I'm unclear about when the 535Q came out,
but mine's just a 535 with the boost trim on the bottom.

jimbob - if you take any pics, I would love to see 'em!

the boost pot *is* connected.  This is a double sided board. All holes are coated through, and tracks run on both sides. The center connection of the pot has a track running from it that then goes to the other side (the "unfilled" hole) the other two will have tracks on the component side.
