Illuminati (33rd Degree)

That's right, Bill. You can add a 0.1uF cap to the 0.33uF cap by connecting them in parallel to form 0.43uF. If you add a couple of 0.1uF per side, you'll have 0.53uF. Raising capacitance across R1 will bring up the treble and bring it in a little sooner.

The stock value is 0.47uF for all networks from 6dB to 12dB. The resistors R1 and R2 set the padding level:

Network R1 R2 C1
================================
6dB 12 30 0.47
8dB 12 20 0.47
10dB 16 16 0.47
12dB 25 16 0.47
================================
