Boosting 25-30 hz

qguy · 11th January 2007, 10:28 PM

Hi how can I boost these frequencies ? (25-30hz)

I was thinking of modifying a graphic equalizer (which I have lying around somewhere) with bands from 50 to 15,000 hz. I reckon i can changed some capacitors / resistors ?

If you are using a plate amp you normally can change the boost frequency and level by 2 resistor changes. Finding those instructions in another matter

If you did all the math correctly then what you were thinking of would work in theory..
Just seems like a lot of work when you can go out and buy a BFD...
