SOLVED Lemonade Overdrive discrepancies

[bluedmc777]

I did a search for this but only came up with 2 results. The current pcb listed on the current bom in the projects section is completely different from pcb I received. The build document is different too. Also, mine had a 100n cap that isn’t listed on the original…it isn’t even on the schematic. Lastly, @music6000 said that his original Lemonade had 2 4.7uf instead of the 2.2ufs. Can someone confirm that the 100n is correct? Also, what perceivable difference did you hear with the 2.2uf @music6000? I’m wondering if the added 100n was maybe added as an alternative to changing the two caps.

Here is a picture of my current board on top along with my crappy build this far vs the old board on bottom along with schematic for old board. Yea I like to socket transistors lol even though the adapter for the bc108 is a tad big. @Robert

Any and all help would be much appreciated. Also curious what the 4 knob version adds and if it could be implemented.

It's just a layout revision (component placement, SMD pads for the 2N5457).

The only difference to the circuit is the addition of the 100nF filter capacitor (C11), and it's completely optional.

I can't comment on 2u2 vs 4u7, but it's mentioned here: https://forum.pedalpcb.com/threads/lemonade-od-more-bass.18026/post-216276

Thanks for the confirmation @Robert. Should’ve socketed the 2 caps but I still have time.

Just tack another 2.2uF across each of them in parallel, you'll have 4.4uF.

That's close enough for testing.

It sounds like there might have been a silent revision to the PCB and BOM. The extra 100n cap could be a decoupling cap added for stability—it's a common practice even if not on the original schematic. As for the capacitor values, swapping 4.7μF for 2.2μF might slightly affect the bass response or filtering thresholds, but it’d be subtle.

@music6000 Did you try with both the 2.2uf and 4.7uf? If so what were your thoughts. Maybe I should just go with a 3.3uf and have the best of both worlds. Or even socket them.
