Hi All,

I was wondering if any of you know how the original DPDT was wired?  I am installing a 3PDT switch to add an LED.

Thanks

Thank you mister!  What I was fuzzy about was the stomp switch wiring!

Hi Brian,
Do you have a wiring diagram for two stuffing two effects in one enclosure using the same 9V source?
How is the output of effect #1 connected to input of effect #2?

Instead of output of effect 1 going to the tip of the out jack it goes right into effect 2 in.

Cool indeed!

Brian,

Have you got a diagram for chaining multiple effects into one enclosure?  What is your opinion on doing this, shielding and decoupling?

Thanks a bunch!

IC1 pin 7 - 4.6v.

Which points should I probe around the tone control?

Thanks!

Any suggestion guys?

IC1 pin 3 is still at 1.3v(supposed to be around 3.4v).  IC3 is good now.

Still have huge volume drop.  Sounds thin.  Bypassed, sounds normal.

Thanks!

The two voltages you highlighted are off a bit. Pin3 of IC1 should be closer to 3-4v. I don't remember what pin7 of IC3 should be off the top of my head but I don't think it's 0. I think you have a solder bridge to the ground plane there.

How about when it' bypassed (in buffer mode). Do you get a volume drop that way, too?

Here are the proper voltages:



No volume drop at all when it is bypassed.  Would it be grounding with pin 3 of IC 3?

I will check that tonight.

Thanks

Hi All:

Wired up using ver 2.  Used a .47uf instead of a .390uf.  All caps are +25v rated.

Here's my issue:
Everything works, but it sounds really thin and there is a huge volume drop.

With that said, I have included some images and here are the voltages of the IC.
IC1 pin 3(+ input) is off, and IC3 pin 7(to + supply) is off.

Doesn't hum.  The pictures showf the .47uf cap almost touching the ic pins, but it doesn't when in place.

IC1
1 - 4.45v
2 - 4.46v
3 - 1.2v ****
4 - 0v
5 - 4.4v
6 - 4.4v
7 - 4.6v
8 - 9v

IC2
1 - 4.6v
2 - 4.6v
3 - 4.6v
4 - -8.7v
5 - 4.5v
6 - 4.6v
7 - 4.6v
8 - 16.9v

IC3
1 - 9.3v
2 - 4.5v
3 - 0
4 - -4.7v
5 - -9.1v
6 - 4.5v
7 - 0v  *****
8 - 9v









Please advise.

Thanks!
