Fast forward to 10:35 for the up close board shots.

Brad The guitologist just got his and takes one apart. Its hybrid smt thru hole, sounds sick as shit.
A500k gain
Bass(booty)c5k
Output 100k
Treble(sizzle)b10k
Opamp ca3240ez(dual bi-mos)
I did spot a sot23 n ch mosfet labeled mv near the clipping switch it also looks to have LEDs in the feedback loop

just was interested in the topology.....

inquiring minds and all that.........

No crackle? That is not ok. :|

And should have used the second opamp as output for proper melting.

So... No output from this power line? What's it's purpose then?

that's how to properly connect an unused opamp

What is the need to use two resistive dividers to have two independent V/2 supply points ? :scratch:

1) easier trace routing

2) less interaction between stages

3) something else(?)

well, yeah, but it could definitely be used for a better purpose.

A little late to the game, but question...

In the video, you can clearly see the values on the original.
There are at least THREE differences I see between the original video footage and Buggs' schematic and board!

1. R21 1k (buggs) => 10k (actual 103)
1. R26 1k (buggs) => 10k (actual 103)
1. A100K (Sizzle) => A10k (VR3)

WHY the differences?? Is there a betterment or else in error and so should use the actual values, which are 10k, 10k, and A10k as I indicated?!?

PLEASE CONFIRM

Might be a mistake but those two resistors being 1k or 10k wont materially affect anything

The sizzle control seems wrong though, maybe that capacitor should be 10n instead of 100n?

I communicated the same to Bugg directly. He's going to check it out and both ways (current and with those values) and see which is better. There may have been some differences in board between video and traced unit. We'll see.

Here's a craptacular tagboard layout I did a couple of months ago based on the pedalpcb schematic. I drew it up with a Ca3140 single instead of a CA3240EZ. No idea if it'll work, haven't built it yet.

{scratches head}

Axldeziak, not sure why you would post a 22x19 vero, unverified, using the 1k's for R21 an R26 and your booty showing the completely incorrect C500K that should be C5k, when there is already a much smaller 21x14 vero out there>?!??

No value add.

I did it for the lulz. I've been wanting to build one of these for awhile now.

Pay attention, I guess that layout wrong.
This should be the verified one:
