Cream Pie (Frantone Cream puff) build sounds very dark
- Thread starter johnk_10
- Start date
i built one years ago with my own etched pcb and, IMO, it sounds a lot better. i'd like to make this new pedalpcb version sound more like it. i'll have to see if i used the same component values in it, so i think that i'll have to mod it.

Check out r11. It looks like one end isn't soldered properly.
just continuity checked it and it's soldered fine.
it turns out that it's actually bright enough sounding, but it has a TON of low end no matter where the tone control is set as compared to my etched PCB version:
all of the values of caps are the same, but i'm thinking that it may be due to using tanalum and MLCC ceramics in places instead of film and aluminum electrolytics.

you might have luck lowering the value of an input or output capacitor
Yeah. Maybe the mlcc are derating due to DC?
X7R don't derate much but Y5V, for instance, can derate to designed 20% capacitance at ~9 volts.
IIRC, tants don't derate much.
DC bias on mlcc can increase microphonic behavior as well.

yeah, i thought about that.
probably the input one. like changing the 1uf to a 470nf or a 220nf.
