Simple stupid mistake

For a while now, I have been trying to use an old Shaka Pedal and for some strange reason, when in bypass, the tone was screwed up. No highs etc.... affected the clean tone a LOT. I immediately assumed it was the switch (Old Carling). Anyway, this poor pedal has had so many mods, it was a jumble of shielded cables, packed tight into a 1590BB box. I noticed I tried the .01uF cap across the output mod etc...

After changing the switch, the same thing happened! Hmmm.... battery touching output jack? Shielded wire affecting bypass? Bad jack....????

Then I recalled the .01uF cap. ARGGGGHHHH in my modding frenzy I had put it across the output JACK! It was affecting everything!

OK, it's all fixed now!  ;D

I know how it feels.  Just recently built the easyvibe and I thought it sounded OK.  But when I was messing with it noticed that one of the sweeps during phasing sounded thin.  Then when the other end of the sweep would kick in it got loud again.  Sounded kind of tremoloy (is that a word?) :icon_rolleyes:  Thinking about the caps I used in the stages for phasing I decided to double check their values.  Sure enough having my head up my #$ss as usual while building it I wrote down the cap value wrong on the schem.  I used a 4.7uF cap instead of a 4.7nF which made sense since I had to figure out which way the polarized 4.7uF electro cap needed to face since the circuit showed a non-polarized symbol.  You'd think that would've clued me in but I wasn't thinking since I had installed a .22uF polarized electro cap just before that.  Well I put the right cap in and it sounds like it should.  Both sweeps are equal and it's much more like it.  What a stupid  :icon_redface: mistake.  I can't believe I did that.
