It's here on page 3?? Maybe?

Search for junk in the trunk. :mrgreen: Or something like that.

It is not verified though..so I could run into problems, but that's why we are here. 8)

it turns out that my posted layout on page 4 is correct. for some reason, my etch had and error where it joined a connection that it shouldn't have. i just cut it with and exacto and it's working fine now.
i just have to go over it to make sure that the pot lug numbering is correct and then i can verify it.

Do I need to scale the pcb image?

BTW, at 300 dpi it should measure 2.25" wide exactly.

I only have bigger boxes so it's going in a BB sized enclosure. The second one I am building will get a smaller enclosure.

:hmmm: :hmmm: But I need really cool 70's style graphics. :whappen:

Hey john!!!

Can you post your voltages? On the chips and at the Zener diode and pitch pot?

I am getting some freq filtering, but not auto filtering.

The right side of my chips are super low voltages.

Thanks!!!!!

Double checking my soldering this weekend. Had the wrong zener diode in them. :slap:

But also, I have 3mm red clear leds instead of the amber...I wonder if the forward bias is different enough to affect the pedal as well??

And does it matter what TL074 I use..I only have TI right now.

Whats yer voltages?

I'm hoping that maybe its just a bad IC or two, but I just can't get it to filter. :cry:

Nice job with that build johnk...looks great!

I bought an Agent 00Funk II this week, I love it!
I remember trying one in the shop when they came out and thought it was a bit peaky & sensitive, but
since I've been using compression in front of envelopes they're much more usable
I was a Mutron freak for years but sold them all off (for cash heh)

I'm sure the Agent Funk has a faster response than the Mutron, I was running a Minifooger Ring into
it earlier and it was totally mad responding to the beat freq...cool stuff!

I sold my last Mutron III a few years back, but that's paid for an Agent 00Funk II, Q-tron+ and a Proteus (with some $ leftover heh)
BTW, I'm a guitarist & Zappa nut, so I needs me envelopes!
