Increase lows on a Big Daddy?

[jayp5150]

I was going to build ROG's Big Daddy for my cousin, but I think he may want some more lows.  Would I increase the .0068uf cap, or am way off.

If that is the correct component, what value?  .01uf?

He plays heavy stuff, drop D/Db mostly.

Thanks, guys.

You can increase that .0068 to .01 or .022 for more bass.  This will also increase distortion, since more signal will be hittiing the input of the 386.  Also, you can increase the 2.2uF FET source bypass cap to 22uF or so.

I suggest that you breadboard the circuit and try some different values and/or use a socket for the input cap when you build the circuit.
