Default Opamp based graphic equalizer

Hi,
I would like to make a dual channel 7 band graphic equalizer (variable Q) for my bass guitar, using 2 opamps each channel.
One channel is a mix of magnetic pickups, the other is piezo pickups. Both channels go through the Graphtech Acoustiphonic buffer prior to equalization.
I wish to use a stacked pot for volumes, and a master volume pot.
Power is a single 9VDC battery.

My skill and understanding of electronics are minimal, as is the space inside the bass, therefor opamps makes sense. So, I wish for the best sounding one that will answer my needs best.

I found these:
BA3812L
M5226
LA3600

Please help me choose which one is best for my application.

Thank you
Adam
