Hello all,

I've built both Supasustain and Soul Preacher (old version) and i like both of them a lot!!!
But, I will love more if I will found some mods to control the attack...:)

Best regards...

I can't see any way to modify the attack, but you could probably vary the gain recovery time on the Soul Preacher by reducing the value of the 4M7 resistor. On the Colorsound unit, it would appear that the time constants are pretty much a result of the LDR properties, and not set by any variable components.

Thank you very much, Mark!
In Soul Preacher I see a 10mF cap on the pin 5 of the opamp...I will try to adjust it, too, as in Orange Squeezer.

Best regards!
