Fix for Fuzz Noise Hash Hiss

[seedlings]

For the Attention Defecit
Add resistance between the + DC jack and the rest of the pedal.

Story
The latest fuzz was sounding all nice and beefy and thick.  Then I put it on the pedal board.  And it sounds good and beefy and thick.  And then (after some fiddling around with pedal order) 'all of the sudden' the fuzz grew a serious hash problem.  So I try the usual trick of small cap across B C of Q1.  Not much help.  Move from .00022 to .001 and finally up to .22 before the hissh tamed.  And the tone of course was affected.  So, then I notice something.  I unplug the pedal from the 1-Spot and (with the 1000uF cap) the pedal plays, hissh is gone while the cap runs out of juice.

So I have a power supply problem of some sort.  Start unplugging pedals and the $8.99 best buy clearance Danelectro delay is the culprit. (This is when I realize the problem did NOT show up 'all of the sudden'.)  What to do...?  Scrap the cheapo yet handy pedal?  Nope.  Then I remember a thread recently about Isolated Power Supplies (http://www.diystompboxes.com/smfforum/index.php?topic=96274.0) and decide to try that fix.  I put a 10K trimmer between the + DC jack and the rest of the pedal, then dial it until the hashhhishh is tamed. I removed the Q1 B-C cap.  9.37V before, 7.9V after.  Sounds great.  I was going to add a cap across the DC jack, but decided it wouldn't be necessary.
