Is my Paralooper layout correct?

[bobbletrox]

I came across the Moosapotamus Bass Paralooper while trying to find some blend and crossover circuits to add to the passive 2 loop bypass dealie I was talkin' about in this thread.  I've only been makin' pedals for a grand total of 4 weeks, and I really need big colorful Fisher-Price diagrams to understand how everything's laid out...so I used this component layout from the moosapotamus site:

...to make this layout with the pots, switches and what have you on it:

Could someone run their more experienced gaze across it to see if it all checks out?  I forgot to add the diode in the upper left corner, and I couldn't tell which of two capacitors in the center area was supposed to be the 10uF or the 100uF (it's hard to tell which the original layout is referring to).

So yeah, is my layout correct, or have I gone completely bonkers?

looks okay. Nice idea with the two switching loops.
If you're using a metal box and metal jacks, only ground the input - the rest is then grounded via the box.
hih

Yeah, the layout looks good to me, too.

As for those two capacitors, the one on the left that connects to lug 1 of the balance pot (VR2-1) is the 10uF (C8 ). The one on the right is the 100uF (C2).

The alternate loop switch is a cool add-on, too. Nice work!

OT: Some of you may have run into this sort of thing before... But, I just discovered that if you try to type 'C8' in parenthesis it comes out looking like this... (C8). So, that's why I left a space when I typed it, above, to make it look regular, sort of... whatever, anyway.  :shock:

Excellent!  Thanks guys!  Thanks for clearing up those capcitor values and the grounding for me too.

Ack!  Two more questions  :oops:

A) What would you reccommend for the diode?  Would just a regular 1N4148 do?
B) The Ballance pot is a 100k linear, and the Level pot is a 100k Log, right?

Thanks.

The diode is there as a protection against reverse polarity (say if you accidentally touch the polarity switch on your adapter). You *could* leave it out and the unit will work fine, but it will be unprotected.
A 4148 is waay to light for this, try a 1N4001 at least or even a 4003 or 4.
A 4148 will fry at the least sign of reverse polarity, so that the pedal is possibly still dead when you've solved the polarity problem.
Balance is lin, level is log, yes.

Great!  Thanks Mike.  Now it's build time.
