Basically this is a extremely simple low pass filtering wah
It might not sound like a crybaby but it has it‘s own lovely charme
The resonance switch can bring this from a subtle wah to a screaming resonant monster
If you feel experimental you can even control the wah with a light dependent resistor
In the end it‘s cheap and fun and you should treat yourself to something weird
Bonus possibillity:
Use this as a pretty extra tone control after (or in front of) any drive pedal!!!
