Problem solved!!!!!  It was the switching board, a bad component.  Just finished up the Blues King as well.  All 3 will be on the pedal board and using with our praise and worship band.........

I have checked voltage on the switching board, there is 9v on everything I check.  Any help or suggestions would be greatly appreciated.  The foot switch is working properly too.

Well, got home from work an finally had time to work on this issue.  Ive got the correct voltage reading on the IC's.  It is an issue with the switching board.  I am trying to track down the component.  I will also finish the Blues King in the morning....hopefully without issues.  The problem with the switching board is it now doesn't toggle between on/off, no power to LED.  Anyone with suggestions?  I have not done anything to the switch board at all, just rewired the connection between the two boards with better quality wire.  I'm sure its a short in the wire?

What should the output voltage be on the switching board?  Mike

The cap is one I had on hand and I wanted to use up some components.  I'll use a low ESR on the next one.  Anyways, I did find a couple resistors I used that are 1/4 watt and the leads are touching the "body" of the itself. would this cause a short or any issues?  I am gonna redo them or at least make some space between.  I used 1/4 watts because I have a boat load of them and need to use some up, maybe should of bought some 1/8 watt resistors.  Thanks.

Ok, feel like I am talking to myself since I just posted the pics....haha.  When I looked at the switching board after making the pics, I looked at the regulator LP 2950.  I ordered my components from mouser.  On the regulator I installed reads KY 5050.  So I looked on the shipping package from mouser and it reads LP 2950 and the other 2 regulators inside the package read KY 5050.  Would this be the problem?   I had one spare regulator LM78L05 from a previous build and used it in the Pale Horse and it works just fine, may look to see if I've got another one.  Mike.

Ok, so here in KY we had a LOT of rain.  Lake Cumberland/Wolf Creek Dam is at 753 feet.  Think that's a record.  I also had a flooded basement as well.  Built my house 20 years ago and first time ever.  Pumped out about 200 gallons of water.  So, I took some pics with my crappy camera.  It's very difficult to see the soldering side since the pots etc are mounted.  I am thinking it is the switching board.  Shouldn't it have 9v at V+ going out?  Thanks for the help!  Mike.

Hey,  It'd been a while since I built a pedal.  So I decided I needed three (3) VFE overdrives.  Blues King, Pale Horse and the Merman.  I am having issues with the Merman.  The pedal works but with very low volume, drive etc.  And when I turn up the drive to full or off, it makes a motor boating type sound.  Any ideas?  Here's the voltages:
IC 1                       IC 2                        IC3
1  2.39   5  4.99      1  2.34    5  5.99      1  5.0     5  5.00
2  2.39   6  2.00      2  2.39    6  2.63      2  2.40   6  2.64
3  1.53   7  2.39      3  2.41    7  2.36      3  3.10   7  1.44
4  2.90   8  2.39      4  0         8  2.41      4  0.00   8  0.00
I was using an ONE Spot when checking voltages which it was putting out 9 volts.   I also checked the voltage of the switching board at V+  and it measured 5.00.  I am thinking this may be the problem???  Not sending 9v to the board?  Thanks for the help and advise!!! 

Thanks, Bluz.

Thanks,  I looked and studied this way to much!!!  Such a simple simple thing to let me get confused.....LOL!!!!!  Ignorance is bliss.......

Ok, so I ordered my parts for this build.  Bought the rotor switch from Mouser. I've read the directions through at least half dozen times. I probably over looked this but......how do I wire this to the board?  I didn't see a wiring diagram, help!......

Thanks for the info. If I can't use an inductor like these I found then anyone have an online vendor that carries an inductor I can use? If not I will try it with the resistor. Thanks! Bluz 

Hey everyone,  I was thinking about building the power pellet.  I have a couple pedals that are noisy and want to tame them,  but the problem is finding the inductor.  I really don't know anything about these inductors.....So, would one like these work?  Thanks, Bluz.

P.S.  anyone know where I can purchase one online like in the project photos?

I took some voltage reading:

IC 1  (1-8) 4.7 4.7 4.7 9.4 0 4.7 4.7 4.3

IC 2  (1-8) 6.9 6.9 6.9 6.9 6.9 6.9 6.9 6.9
        (9-16) 8.6 8.6 9.4 7.4 9.4 9.4 6.8 4.4

IC3  (1-8) 8.8 4.7 9.4 9.4 0 4.7 4.8 4.8

I have used my audio probe what little time I've had today and haven't any other problems other than R16 being broken.  I've not had time to take pics yet.  Thanks, Mike.

I found R16 (1M5) to be broken some how and I replaced it.....sound through the amp with switch on w/o any delay effect....., replaced all IC's, no change. Couldn't find any other problems so far. Any one with any ideas?  Thanks, Mike.

Ok, so I walked away and left it alone for a while to mow my lawn....I powered up the amp, plugged in the ZPM and now I don't even have any delay.....I've not changed anything.  When I engage the footswitch the led lights up and I have sound but no modulation/delay/etc.....stumped!!!!!  Puuuuzzzzllled!  I checked power to all IC's, etc.  Guess its time for the audio probe.....any ideas? tips or help?  Thanks, Mike.
