Weslie - Sort of Leslie Simulator

[fx-fidden]

Hello, I found this project by General Guitar Gadget:
https://generalguitargadgets.com/effects-projects/modulationecho/weslie-modulator/

It's a kind of Leslie simulator, it's more a warble effect, but it's pretty unique and new to build.

Here's a demo:

It seems to have a volume drop, maybe a booster after the circuit could be useful.

I tried to draw a veroboard layout (no boost).

That's it, unverified.



Tell me if I made some mistake.

Edit:
Now is VERIFIED.

Nice one, thanks for sharing

Hi, thanks i used this layout and it works after these changes:

reverse D2
cut the track at C-10

if anyone doesn't know this already, the GGG circuit is a copy of this PAiA circuit that was published in popular electronics:

except the GGG circuit uses newer transistors and a 3PDT switch instead of using a light bulb and an LDR for the bypass switch

Great! I had totally forgotten this effect.

Thanks for verifying it.
